Llano Estacado
–
Llano Estacado commonly known as the Staked Plain, is a region in the Southwestern United States that encompasses parts of eastern New Mexico and northwestern Texas. The Llano Estacado lies at the end of the Western High Plains ecoregion of the Great Plains of North America. The Canadian River forms the Llanos northern boundary, separating it from the rest of the High Plains, the Llano has no natural southern boundary, instead blending into the Edwards Plateau near Big Spring, Texas. This geographic area stretches about 250 miles north to south, and 150 miles east to west and it covers all or part of 33 Texas counties and four New Mexico counties. The landscape is dotted by numerous small lakes, depressions that seasonally fill with water. The Llano Estacado has a semiarid climate, characterized by long, hot summers. Rainfall is very low, the region receives fewer than 23 in of rainfall annually. High summer temperatures mean most of the amount of precipitation is lost to evaporation. The Texas State Historical Society states it covers all or part of 33 Texas counties, six fewer than as depicted by a US Geological Survey map, interstate 40 crosses the northern portion from east of Amarillo to Tucumcari, New Mexico. There was not a stone, nor bit of rising ground, nor a tree, nor a shrub, in the early 18th century, the Comanches expanded their territory into the Llano Estacado, displacing the Apaches who had previously lived there. The region became part of the Comancheria, a Comanche stronghold until the defeat of the tribe in the late 19th century. Rachel Plummer, while a captive of the Comanche in 1836, after his 1852 expedition to explore the headwaters of the Red and Colorado Rivers, General Randolph Marcy wrote, a tree, shrub, or any other herbage to intercept the vision. The almost total absence of water causes all animals to shun it, in his report for the United States Army, When we were upon the high table-land, a view presented itself as boundless as the ocean. Not a tree, shrub, or any object, either animate or inanimate, relieved the dreary monotony of the prospect. The great Sahara of North America and it is a region almost as vast and trackless as the ocean—a land where no man, either savage or civilized permanently abides. A treeless, desolate waste of uninhabitable solitude, which always has been, during the 1854 Marcy-Neighbors expedition, Dr. George Getz Shumard noted, Beyond the mountain appeared a line of high bluffs which in the distance looked like clouds floating upon the horizon. Herman Lehmann was captured by the Apache in 1870 and described the Llano Estacado as the country was open, but not exactly a desert. Robert G. Carter described it in 1871 while pursuing Quanah Parker with Ranald S. Mackenzie. all were over and out of the canyon upon what appeared to be a vast, almost illimitable expanse of prairie

Midwestern United States
–
It was officially named the North Central region by the Census Bureau until 1984. Illinois is the most populous of the states and North Dakota the least, a 2012 report from the United States Census put the population of the Midwest at 65,377,684. The Midwest is divided by the Census Bureau into two divisions, the East North Central Division includes Illinois, Indiana, Michigan, Ohio and Wisconsin, all of which are also part of the Great Lakes region. Major rivers in the include, from east to west, the Ohio River, the Upper Mississippi River. Chicago is the most populated city in the American Midwest and the third most populous in the entire country, other large Midwest cities include, Indianapolis, Columbus, Detroit, Milwaukee, Kansas City, Omaha, Minneapolis, Cleveland, Wichita and St. Louis. Chicago and its suburbs form the largest metropolitan area with 9.8 million people, followed by Metro Detroit. Paul, Greater St. Louis, Greater Cleveland, Greater Cincinnati, Kansas City metro area, the term Midwestern has been in use since the 1880s to refer to portions of the central United States. A variant term, Middle West, has used since the 19th century. Another term sometimes applied to the general region is the heartland. Other designations for the region have fallen out of use, such as the Northwest or Old Northwest, the Northwest Territory was one of the earliest territories of the United States, stretching northwest from the Ohio River to northern Minnesota and upper-Mississippi. The upper-Mississippi watershed including the Missouri and Illinois Rivers was the setting for the earlier French settlements of the Illinois Country, economically the region is balanced between heavy industry and agriculture, with finance and services such as medicine and education becoming increasingly important. Its central location makes it a crossroads for river boats, railroads, autos, trucks. Politically the region swings back and forth between the parties, and thus is heavily contested and often decisive in elections, after the sociological study Middletown, which was based on Muncie, Indiana, commentators used Midwestern cities as typical of the nation. The region has a higher ratio than the Northeast, the West. Traditional definitions of the Midwest include the Northwest Ordinance Old Northwest states, the states of the Old Northwest are also known as Great Lakes states and are east-north central in the United States. The Ohio River runs along the section while the Mississippi River runs north to south near the center. Many of the Louisiana Purchase states in the west-north central United States, are known as Great Plains states. The Midwest lies north of the 36°30′ parallel that the 1820 Missouri Compromise established as the line between future slave and non-slave states

United States
–
Forty-eight of the fifty states and the federal district are contiguous and located in North America between Canada and Mexico. The state of Alaska is in the northwest corner of North America, bordered by Canada to the east, the state of Hawaii is an archipelago in the mid-Pacific Ocean. The U. S. territories are scattered about the Pacific Ocean, the geography, climate and wildlife of the country are extremely diverse. At 3.8 million square miles and with over 324 million people, the United States is the worlds third- or fourth-largest country by area, third-largest by land area. It is one of the worlds most ethnically diverse and multicultural nations, paleo-Indians migrated from Asia to the North American mainland at least 15,000 years ago. European colonization began in the 16th century, the United States emerged from 13 British colonies along the East Coast. Numerous disputes between Great Britain and the following the Seven Years War led to the American Revolution. On July 4,1776, during the course of the American Revolutionary War, the war ended in 1783 with recognition of the independence of the United States by Great Britain, representing the first successful war of independence against a European power. The current constitution was adopted in 1788, after the Articles of Confederation, the first ten amendments, collectively named the Bill of Rights, were ratified in 1791 and designed to guarantee many fundamental civil liberties. During the second half of the 19th century, the American Civil War led to the end of slavery in the country. By the end of century, the United States extended into the Pacific Ocean. The Spanish–American War and World War I confirmed the status as a global military power. The end of the Cold War and the dissolution of the Soviet Union in 1991 left the United States as the sole superpower. The U. S. is a member of the United Nations, World Bank, International Monetary Fund, Organization of American States. The United States is a developed country, with the worlds largest economy by nominal GDP. It ranks highly in several measures of performance, including average wage, human development, per capita GDP. While the U. S. economy is considered post-industrial, characterized by the dominance of services and knowledge economy, the United States is a prominent political and cultural force internationally, and a leader in scientific research and technological innovations. In 1507, the German cartographer Martin Waldseemüller produced a map on which he named the lands of the Western Hemisphere America after the Italian explorer and cartographer Amerigo Vespucci

Canada
–
Canada is a country in the northern half of North America. Canadas border with the United States is the worlds longest binational land border, the majority of the country has a cold or severely cold winter climate, but southerly areas are warm in summer. Canada is sparsely populated, the majority of its territory being dominated by forest and tundra. It is highly urbanized with 82 per cent of the 35.15 million people concentrated in large and medium-sized cities, One third of the population lives in the three largest cities, Toronto, Montreal and Vancouver. Its capital is Ottawa, and other urban areas include Calgary, Edmonton, Quebec City, Winnipeg. Various aboriginal peoples had inhabited what is now Canada for thousands of years prior to European colonization. Pursuant to the British North America Act, on July 1,1867, the colonies of Canada, New Brunswick and this began an accretion of provinces and territories to the mostly self-governing Dominion to the present ten provinces and three territories forming modern Canada. With the Constitution Act 1982, Canada took over authority, removing the last remaining ties of legal dependence on the Parliament of the United Kingdom. Canada is a parliamentary democracy and a constitutional monarchy, with Queen Elizabeth II being the head of state. The country is officially bilingual at the federal level and it is one of the worlds most ethnically diverse and multicultural nations, the product of large-scale immigration from many other countries. Its advanced economy is the eleventh largest in the world, relying chiefly upon its abundant natural resources, Canadas long and complex relationship with the United States has had a significant impact on its economy and culture. Canada is a country and has the tenth highest nominal per capita income globally as well as the ninth highest ranking in the Human Development Index. It ranks among the highest in international measurements of government transparency, civil liberties, quality of life, economic freedom, Canada is an influential nation in the world, primarily due to its inclusive values, years of prosperity and stability, stable economy, and efficient military. While a variety of theories have been postulated for the origins of Canada. In 1535, indigenous inhabitants of the present-day Quebec City region used the word to direct French explorer Jacques Cartier to the village of Stadacona, from the 16th to the early 18th century Canada referred to the part of New France that lay along the St. Lawrence River. In 1791, the area became two British colonies called Upper Canada and Lower Canada collectively named The Canadas, until their union as the British Province of Canada in 1841. Upon Confederation in 1867, Canada was adopted as the name for the new country at the London Conference. The transition away from the use of Dominion was formally reflected in 1982 with the passage of the Canada Act, later that year, the name of national holiday was changed from Dominion Day to Canada Day

Geographic coordinate system
–
A geographic coordinate system is a coordinate system used in geography that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are chosen such that one of the numbers represents a vertical position. A common choice of coordinates is latitude, longitude and elevation, to specify a location on a two-dimensional map requires a map projection. The invention of a coordinate system is generally credited to Eratosthenes of Cyrene. Ptolemy credited him with the adoption of longitude and latitude. Ptolemys 2nd-century Geography used the prime meridian but measured latitude from the equator instead. Mathematical cartography resumed in Europe following Maximus Planudes recovery of Ptolemys text a little before 1300, in 1884, the United States hosted the International Meridian Conference, attended by representatives from twenty-five nations. Twenty-two of them agreed to adopt the longitude of the Royal Observatory in Greenwich, the Dominican Republic voted against the motion, while France and Brazil abstained. France adopted Greenwich Mean Time in place of local determinations by the Paris Observatory in 1911, the latitude of a point on Earths surface is the angle between the equatorial plane and the straight line that passes through that point and through the center of the Earth. Lines joining points of the same latitude trace circles on the surface of Earth called parallels, as they are parallel to the equator, the north pole is 90° N, the south pole is 90° S. The 0° parallel of latitude is designated the equator, the plane of all geographic coordinate systems. The equator divides the globe into Northern and Southern Hemispheres, the longitude of a point on Earths surface is the angle east or west of a reference meridian to another meridian that passes through that point. All meridians are halves of great ellipses, which converge at the north and south poles, the prime meridian determines the proper Eastern and Western Hemispheres, although maps often divide these hemispheres further west in order to keep the Old World on a single side. The antipodal meridian of Greenwich is both 180°W and 180°E, the combination of these two components specifies the position of any location on the surface of Earth, without consideration of altitude or depth. The grid formed by lines of latitude and longitude is known as a graticule, the origin/zero point of this system is located in the Gulf of Guinea about 625 km south of Tema, Ghana. To completely specify a location of a feature on, in, or above Earth. Earth is not a sphere, but a shape approximating a biaxial ellipsoid. It is nearly spherical, but has an equatorial bulge making the radius at the equator about 0. 3% larger than the radius measured through the poles, the shorter axis approximately coincides with the axis of rotation

Plain
–
In geography, a plain is a flat, sweeping landmass that generally does not change much in elevation. Plains occur as lowlands along the bottoms of valleys or on the doorsteps of mountains, as coastal plains, and as plateaus or uplands. In a valley, a plain is enclosed on two sides but in other cases a plain may be delineated by a complete or partial ring of hills, where a geological region contains more than one plain, they may be connected by a pass. Coastal plains would mostly rise from sea level until they run into elevated features such as mountains or plateaus, plains are one of the major landforms on earth, where they are present on all continents, and would cover more than one-third of the world’s land area. Plains may have formed from flowing lava, deposited by water, ice, wind, or formed by erosion by these agents from hills. Plains would generally be under the grassland, steppe, savannah or tundra biomes, in a few instances, deserts and rainforests can also be plains. Structural plains are relatively undisturbed horizontal surfaces of the Earth and they are structurally depressed areas of the world that make up some of the most extensive natural lowlands on the Earths surface. Erosional plains have been leveled by various agents of such as running water, rivers, wind and glacier which wear out the rugged surface. Plain resulting from the action of these agents of denudation are called peneplains while plains formed from wind action are called pediplains, depositional plains formed by the deposition of materials brought by various agents of transportation such as rivers, wind, waves, and glaciers. Their fertility and economic relevance depend greatly on the types of sediments that are laid down, flood plain, adjacent to a stream, river, lake or wetland that experiences occasional or periodic flooding. Scroll plain, a plain through which a river meanders with a low gradient. Lacustrine plain, a plain that originally formed in a lacustrine environment, lava plain, formed by sheets of flowing lava. Glacial plains, formed by the movement of glaciers under the force of gravity, Sandur, sandar consist mainly of stratified gravel and sand. Till plain, a plain of glacial till that forms when a sheet of ice becomes detached from the body of a glacier. Till plains are composed of unsorted material of all sizes, abyssal plain, a flat or very gently sloping area of the deep ocean basin. Planitia, the Latin word for plain, is used in the naming of plains on extraterrestrial objects, such as Hellas Planitia on Mars or Sedna Planitia on Venus

Prairie
–
Temperate grassland regions include the Pampas of Argentina, southern Brazil and Uruguay as well as the steppes of Eurasia. Lands typically referred to as prairie tend to be in North America, the Central Valley of California is also a prairie. The Canadian Prairies occupy vast areas of Manitoba, Saskatchewan, Prairie is the French word for meadow, but the ultimate root is the Latin pratum. The formation of the North American Prairies started with the upwelling of the Rocky Mountains near Alberta, the mountains created a rain shadow that resulted in lower precipitation rates downwind, creating an environment in which most tree species will not tolerate. The parent material of most prairie soil was distributed during the last glacial advance that began about 110,000 years ago, the glaciers expanding southward scraped the landscape, picking up geologic material and leveling the terrain. As the glaciers retreated about 10,000 years ago, it deposited this material in the form of till, wind based loess deposits also form an important parent material for prairie soils. Tallgrass Prairie evolved over tens of thousands of years with the disturbances of grazing, native ungulates such as bison, elk, and white-tailed deer, roamed the expansive, diverse, plentiful grassland before European colonization of the Americas. For 10, 000-20,000 years native people used fire annually as a tool to assist in hunting, transportation, evidence of ignition sources of fire in the tallgrass prairie are overwhelmingly human as opposed to lightning. Humans, and grazing animals, were participants in the process of prairie formation. Fire has the effect on prairies of removing trees, clearing dead plant matter, fire kills the vascular tissue of trees, but not prairie, as up to 75% of the total plant biomass is below the soil surface and will re-grow from its deep roots. Without disturbance, trees will encroach on a grassland, cast shade, Prairie and widely spaced oak trees evolved to coexist in the oak savanna ecosystem. In spite of long recurrent droughts and occasional torrential rains, the grasslands of the Great Plains were not subject to soil erosion. The root systems of native prairie grasses firmly held the soil in place to prevent run-off of soil, when the plant died, the fungi, bacteria returned its nutrients to the soil. These deep roots also helped native prairie plants reach water in even the driest conditions, the native grasses suffered much less damage from dry conditions than the farm crops currently grown. Prairie in North America is usually split into three groups, wet, mesic, and dry and they are generally characterized by tallgrass prairie, mixed, or shortgrass prairie, depending on the quality of soil and rainfall. In wet prairies the soil is very moist, including during most of the growing season. The resulting stagnant water is conducive to the formation of bogs, wet prairies have excellent farming soil. The average precipitation amount is 10-30 inches a year, mesic prairie /ˈmiːzɪk/ has good drainage, but good soil during the growing season

Steppe
–
In South Africa they are referred to as Veld. The prairie is an example of a steppe, though it is not usually called such and it may be semi-desert, or covered with grass or shrubs or both, depending on the season and latitude. The term is used to denote the climate encountered in regions too dry to support a forest. The soil is typically of chernozem type, steppes are usually characterized by a semi-arid and continental climate. Extremes can be recorded in the summer of up to 45 °C and in winter, besides this huge difference between summer and winter, the differences between day and night are also very great. In the highlands of Mongolia,30 °C can be reached during the day with sub-zero °C readings at night, the mid-latitude steppes can be summarized by hot summers and cold winters, averaging 250–510 mm of precipitation per year. Precipitation level alone is not what defines a steppe climate, potential evapotranspiration must also be taken into account, the Eurasian Grass-Steppe of the temperate grasslands, savannas, and shrublands had a role in the spread of the horse, the wheel, and the Indo-European languages. The Indo-European expansion and diverse invasions of horse archer civilizations of the steppe eventually led to, the Pannonian Plain is another steppe region in eastern Europe, primarily Hungary. Another large steppe area is located in the central United States, western Canada, the shortgrass prairie steppe is the westernmost part of the Great Plains region. The Channeled Scablands in Southern British Columbia and Washington State is an example of a region in North America outside of the Great Plains. In South America, cold steppe can be found in Patagonia, relatively small steppe areas can be found in the interior of the South Island of New Zealand. In Asia, a subtropical steppe can be found in semi-arid lands that fringe the Thar Desert of the Indian subcontinent, in Australia, subtropical steppe can be found in a belt surrounding the most severe deserts of the continent and around the Musgrave Ranges.

Grassland
–
Grasslands are areas where the vegetation is dominated by grasses, however sedge and rush families can also be found. Grasslands occur naturally on all continents except Antarctica, grasslands are found in most ecoregions of the Earth. For example, there are five terrestrial ecoregion classifications of the grasslands, savannas, and shrublands biome. Grassland vegetation can vary in height from short, as in chalk grassland, to quite tall, as in the case of North American tallgrass prairie, South American grasslands. Woody plants, shrubs or trees, may occur on some grasslands – forming savannas, scrubby grassland or semi-wooded grassland, as flowering plants and trees, grasses grow in great concentrations in climates where annual rainfall ranges between 500 and 900 mm. The root systems of perennial grasses and forbs form complex mats that hold the soil in place, graminoids are among the most versatile life forms. Existing forest biomes declined, and grasslands became much more widespread, following the Pleistocene ice ages, grasslands expanded in range in the hotter, drier climates, and began to become the dominant land feature worldwide. Grasslands often occur in areas with annual precipitation between 600 mm and 1,500 mm and average annual temperatures ranges from −5 and 20 °C. However, some occur in colder and hotter climatic conditions. Grassland can exist in habitats that are disturbed by grazing or fire. Grasslands dominated by unsown wild-plant communities can be called natural or semi-natural habitats. The majority of grasslands in temperate climates are semi-natural and these grasslands contain many species of wild plants – grasses, sedges, rushes and herbs –25 or more species per square metre is not unusual. Chalk downlands in England can support over 40 species per square metre, in many parts of the world, few examples have escaped agricultural improvement. For example, original North American prairie grasslands or lowland wildflower meadows in the UK are now rare and their associated wild flora equally threatened. Some of the worlds largest expanses of grassland are found in African savanna, grasslands may occur naturally or as the result of human activity. Grasslands created and maintained by human activity are called anthropogenic grasslands, hunting peoples around the world often set regular fires to maintain and extend grasslands, and prevent fire-intolerant trees and shrubs from taking hold. The tallgrass prairies in the U. S. Midwest may have been extended eastward into Illinois, Indiana, much grassland in northwest Europe developed after the Neolithic Period, when people gradually cleared the forest to create areas for raising their livestock.

Mississippi River
–
The Mississippi River is the chief river of the largest drainage system on the North American continent. Flowing entirely in the United States, it rises in northern Minnesota, with its many tributaries, the Mississippis watershed drains all or parts of 31 U. S. states and 2 Canadian provinces between the Rocky and Appalachian Mountains. The Mississippi ranks as the fourth longest and fifteenth largest river in the world by discharge, the river either borders or passes through the states of Minnesota, Wisconsin, Iowa, Illinois, Missouri, Kentucky, Tennessee, Arkansas, Mississippi, and Louisiana. Native Americans long lived along the Mississippi River and its tributaries, most were hunter-gatherers, but some, such as the Mound Builders, formed prolific agricultural societies. The arrival of Europeans in the 16th century changed the way of life as first explorers, then settlers. The river served first as a barrier, forming borders for New Spain, New France, and the early United States, and then as a vital transportation artery and communications link. Formed from thick layers of the silt deposits, the Mississippi embayment is one of the most fertile agricultural regions of the country. In recent years, the river has shown a shift towards the Atchafalaya River channel in the Delta. The word itself comes from Messipi, the French rendering of the Anishinaabe name for the river, see below in the History section for additional information. In addition to historical traditions shown by names, there are at least two measures of a rivers identity, one being the largest branch, and the other being the longest branch. Using the largest-branch criterion, the Ohio would be the branch of the Lower Mississippi. Using the longest-branch criterion, the Middle Mississippi-Missouri-Jefferson-Beaverhead-Red Rock-Hellroaring Creek River would be the main branch and its length of at least 3,745 mi is exceeded only by the Nile, the Amazon, and perhaps the Yangtze River among the longest rivers in the world. The source of this waterway is at Browers Spring,8,800 feet above sea level in southwestern Montana and this is exemplified by the Gateway Arch in St. Louis and the phrase Trans-Mississippi as used in the name of the Trans-Mississippi Exposition. It is common to qualify a regionally superlative landmark in relation to it, the New Madrid Seismic Zone along the river is also noteworthy. These various basic geographical aspects of the river in turn underlie its human history and present uses of the waterway, the Upper Mississippi runs from its headwaters to its confluence with the Missouri River at St. Louis, Missouri. The source of the Upper Mississippi branch is traditionally accepted as Lake Itasca,1,475 feet above sea level in Itasca State Park in Clearwater County, however, the lake is in turn fed by a number of smaller streams. From its origin at Lake Itasca to St. Louis, Missouri, fourteen of these dams are located above Minneapolis in the headwaters region and serve multiple purposes, including power generation and recreation. The remaining 29 dams, beginning in downtown Minneapolis, all locks and were constructed to improve commercial navigation of the upper river

Tallgrass prairie
–
The tallgrass prairie is an ecosystem native to central North America. They were characteristically found in the central forest-grasslands transition, the tall grasslands, the upper Midwest forest-savanna transition. They flourished in areas with loess soils and moderate rainfall around 30 to 35 inches per year. To the east were the eastern savannas. In the northeast, where fire was infrequent and periodic windthrow represented the source of disturbance. In contrast, shortgrass prairie was typical in the western Great Plains, due to expansive agricultural land use, very little tallgrass prairie remains. Retreating glaciers deposited the parent material for soil in the form of till, i. e. unsorted sediment, wind-dropped loess and organic matter accumulated, resulting in deep levels of topsoil. Animals such as bison, elk, deer, and rabbits added nitrogen to the soil through urine, Prairie dogs, a ground squirrel-like rodent considered to be a keystone species, dug tunnels that aerated the soil and channeled water several feet below the surface. For 5,000 to 8,000 years, more than 240 million acres of prairie grasslands were a feature of the landscape. Between 1800 and 1930, the vast majority was destroyed, settlers transformed what they named the Great American Desert or The Inland Sea into farmland. Further, extensive tile drainage has changed the water content and hydrodynamics. Tallgrass prairie is capable of supporting significant biodiversity, parts of the ecoregion among the top ten ecoregions for reptiles, birds, butterflies, and tree species. Tallgrass species are found in the understory layer, oak and hickory tree species occur in some areas, but generally in moderate densities. The tallgrass prairie biome depends on fires, a form of wildfire. Tree seedlings and intrusive alien species without fire tolerance are eliminated by periodic fires, such fires may either be set by humans or started naturally by lightning. Technically, prairies have less than 5–11% tree cover, a grass-dominated plant community with 10–49% tree cover is a savanna. After the steel plow was invented by John Deere, this fertile soil became one of Americas most important resources, over 95% of the original tallgrass prairie is now farmland. In Oklahoma, the tallgrass prairie has been maintained by ranchers and they have reintroduced plains bison to the vast expanses of grass

Rocky Mountains
–
The Rocky Mountains, commonly known as the Rockies, are a major mountain range in western North America. The Rocky Mountains stretch more than 3,000 miles from the northernmost part of British Columbia, in western Canada, to New Mexico, in the Southwestern United States. Within the North American Cordillera, the Rockies are somewhat distinct from the Pacific Coast Ranges, the Rocky Mountains were initially formed from 80 million to 55 million years ago during the Laramide orogeny, in which a number of plates began to slide underneath the North American plate. The angle of subduction was shallow, resulting in a belt of mountains running down western North America. Since then, further tectonic activity and erosion by glaciers have sculpted the Rockies into dramatic peaks, at the end of the last ice age, humans started to inhabit the mountain range. The first mention of their present name by a European was in the journal of Jacques Legardeur de Saint-Pierre in 1752, the Rocky Mountains are commonly defined as stretching from the Liard River in British Columbia south to the Rio Grande in New Mexico. The United States definition of the Rockies includes the Cabinet and Salish Mountains of Idaho and their counterparts north of the Kootenai River, the Columbia Mountains, are considered a separate system in Canada, lying to the west of the huge Rocky Mountain Trench. This runs the length of British Columbia from its beginnings in the middle Flathead River valley in western Montana to the bank of the Liard River. The Rockies vary in width from 70 to 300 miles, also west of the Rocky Mountain Trench, farther north and facing the Muskwa Range across the trench, are the Stikine Ranges and Omineca Mountains of the Interior Mountains system of British Columbia. A small area east of Prince George, British Columbia on the side of the Trench. In Canada geographers define three main groups of ranges, the Continental Ranges, Hart Ranges and Muskwa Ranges, the Muskwa and Hart Ranges together comprise what is known as the Northern Rockies. The western edge of the Rockies includes ranges such as the Wasatch near Salt Lake City, the Great Basin and Columbia River Plateau separate these sub-ranges from distinct ranges further to the west, most prominent among which are the Sierra Nevada, Cascade Range and Coast Mountains. The Rocky Mountain System within the United States is a United States physiographic region, the Rocky Mountains are notable for containing the highest peaks in central North America. The ranges highest peak is Mount Elbert located in Colorado at 14,440 feet above sea level, Mount Robson in British Columbia, at 12,972 feet, is the highest peak in the Canadian Rockies. The Continental Divide of the Americas is located in the Rocky Mountains, triple Divide Peak in Glacier National Park is so named because water that falls on the mountain reaches not only the Atlantic and Pacific, but Hudson Bay as well. Farther north in Alberta, the Athabasca and other rivers feed the basin of the Mackenzie River, see Rivers of the Rocky Mountains for a list of rivers. Human population is not very dense in the Rocky Mountains, with an average of four people per square kilometer, however, the human population grew rapidly in the Rocky Mountain states between 1950 and 1990. The 40-year statewide increases in range from 35% in Montana to about 150% in Utah

U.S. state
–
A U. S. state is a constituent political entity of the United States of America. There are 50 states, which are together in a union with each other. Each state holds administrative jurisdiction over a geographic territory. Due to the shared sovereignty between each state and the government, Americans are citizens of both the federal republic and of the state in which they reside. State citizenship and residency are flexible, and no government approval is required to move between states, except for persons covered by certain types of court orders. States range in population from just under 600,000 to over 39 million, four states use the term commonwealth rather than state in their full official names. States are divided into counties or county-equivalents, which may be assigned some local authority but are not sovereign. County or county-equivalent structure varies widely by state, State governments are allocated power by the people through their individual constitutions. All are grounded in principles, and each provides for a government. States possess a number of powers and rights under the United States Constitution, Constitution has been amended, and the interpretation and application of its provisions have changed. The general tendency has been toward centralization and incorporation, with the government playing a much larger role than it once did. There is a debate over states rights, which concerns the extent and nature of the states powers and sovereignty in relation to the federal government. States and their residents are represented in the federal Congress, a legislature consisting of the Senate. Each state is represented in the Senate by two senators, and is guaranteed at least one Representative in the House, members of the House are elected from single-member districts. Representatives are distributed among the states in proportion to the most recent constitutionally mandated decennial census, the Constitution grants to Congress the authority to admit new states into the Union. Since the establishment of the United States in 1776, the number of states has expanded from the original 13 to 50, alaska and Hawaii are the most recent states admitted, both in 1959. The Constitution is silent on the question of states have the power to secede from the Union. Shortly after the Civil War, the U. S. Supreme Court, in Texas v. White, as a result, while the governments of the various states share many similar features, they often vary greatly with regard to form and substance

Kansas
–
Kansas /ˈkænzəs/ is a U. S. state located in the Midwestern United States. Its capital is Topeka and its largest city is Wichita, Kansas is named after the Kansa Native American tribe, which inhabited the area. The tribes name is said to mean people of the wind or people of the south wind. For thousands of years, what is now Kansas was home to numerous, tribes in the eastern part of the state generally lived in villages along the river valleys. Tribes in the part of the state were semi-nomadic and hunted large herds of bison. When it was opened to settlement by the U. S. Thus, the area was a hotbed of violence and chaos in its early days as these forces collided. The abolitionists eventually prevailed, and on January 29,1861, after the Civil War, the population of Kansas grew rapidly when waves of immigrants turned the prairie into farmland. By 2015, Kansas was one of the most productive agricultural states, producing high yields of wheat, corn, sorghum, and soybeans. Kansas, which has an area of 82,278 square miles is the 15th largest state by area and is the 34th most populous of the 50 United States with a population of 2,911,641, residents of Kansas are called Kansans, officially. Mount Sunflower is Kansass highest point at 4,041 feet, for a millennia, the land that is currently Kansas was inhabited by Native Americans. The first European to set foot in present-day Kansas was Francisco Vázquez de Coronado, in 1803, most of modern Kansas was secured by the United States as part of the Louisiana Purchase. Southwest Kansas, however, was still a part of Spain, Mexico, from 1812 to 1821, Kansas was part of the Missouri Territory. The Santa Fe Trail traversed Kansas from 1821 to 1880, transporting manufactured goods from Missouri and silver and furs from Santa Fe, wagon ruts from the trail are still visible in the prairie today. In 1827, Fort Leavenworth became the first permanent settlement of white Americans in the future state, the Kansas–Nebraska Act became law on May 30,1854, establishing the U. S. territories of Nebraska and Kansas, and opening the area to broader settlement by whites. Kansas Territory stretched all the way to the Continental Divide and included the sites of present-day Denver, Colorado Springs, Missouri and Arkansas sent settlers into Kansas all along its eastern border. These settlers attempted to sway votes in favor of slavery, the secondary settlement of Americans in Kansas Territory were abolitionists from Massachusetts and other Free-Staters, who attempted to stop the spread of slavery from neighboring Missouri. Directly presaging the American Civil War, these forces collided, entering into skirmishes that earned the territory the name of Bleeding Kansas, Kansas was admitted to the United States as a free state on January 29,1861, making it the 34th state to enter the Union. He was roundly condemned by both the conventional Confederate military and the partisan rangers commissioned by the Missouri legislature and his application to that body for a commission was flatly rejected due to his pre-war criminal record

Nebraska
–
Nebraska /nᵻˈbræskə/ is a state that lies in both the Great Plains and the Midwestern United States. Its area is just over 77,220 sq mi with almost 1.9 million people and its largest city is Omaha, which is on the Missouri River. The state is crossed by many trails and was explored by the Lewis. Nebraska was admitted as the 37th state of the United States in 1867 and it is the only state in the United States whose legislature is unicameral and officially nonpartisan. Nebraska is composed of two major regions, the Dissected Till Plains and the Great Plains. The Dissected Till Plains is a region of rolling hills. The Great Plains occupy most of western Nebraska, characterized by treeless prairie, the state has a large agriculture sector and is a major producer of beef, pork, corn, and soybeans. Two major climatic zones are represented in Nebraska, the half of the state has a humid continental climate, and the western half. Indigenous peoples lived in the region of present-day Nebraska for thousands of years before European exploration. The historic tribes in the state included the Omaha, Missouria, Ponca, Pawnee, Otoe, when European exploration, trade, and settlement began, both Spain and France sought to control the region. In the 1690s, Spain established trade connections with the Apaches, by 1703, France had developed a regular trade with the native peoples along the Missouri River in Nebraska, and by 1719 had signed treaties with several of these peoples. After war broke out between the two countries, Spain dispatched an expedition to Nebraska under Lieutenant General Pedro de Villasur in 1720. The party was attacked and destroyed near present-day Columbus by a force of Pawnees and Otoes. The massacre of the Villasur expedition effectively put an end to Spanish exploration of Nebraska for the remainder of the 18th century, in 1762, during the Seven Years War, France ceded the Louisiana territory to Spain. Frances withdrawal from the area left Britain and Spain competing for dominance along the Mississippi, by 1773, later that year, Mackays party built a trading post, dubbed Fort Carlos IV, near present-day Homer. In 1819, the United States established Fort Atkinson as the first U. S. Army post west of the Missouri River, the army abandoned the fort in 1827 as migration moved further west. European-American settlement did not begin in any numbers until after 1848, on May 30,1854, the US Congress created the Kansas and the Nebraska territories, divided by the Parallel 40° North, under the Kansas–Nebraska Act. The Nebraska Territory included parts of the current states of Colorado, North Dakota, South Dakota, Wyoming, the territorial capital of Nebraska was Omaha

North Dakota
–
North Dakota is the 39th state of the United States, having been admitted to the union on November 2,1889. The state capital is Bismarck, and the largest city is Fargo, North Dakota is the 19th most extensive but the 4th least populous and the 4th least densely populated of the 50 United States. The development has driven strong job and population growth, and low unemployment, North Dakota is located in the U. S. region known as the Great Plains. The state shares the Red River of the North with Minnesota on the east, South Dakota is to the south, Montana is to the west, and the Canadian provinces of Saskatchewan and Manitoba are to the north. North Dakota is situated near the middle of North America with a marker in Rugby. With an area of 70,762 square miles, North Dakota is the 19th largest state, the western half of the state consists of the hilly Great Plains as well as the northern part of the Badlands, which are to the west of the Missouri River. The states high point, White Butte at 3,506 feet, the region is abundant in fossil fuels including natural gas, crude oil and lignite coal. The Missouri River forms Lake Sakakawea, the third largest man-made lake in the United States, the central region of the state is divided into the Drift Prairie and the Missouri Plateau. The eastern part of the consists of the flat Red River Valley. Its fertile soil, drained by the meandering Red River flowing northward into Lake Winnipeg, Devils Lake, the largest natural lake in the state, is also found in the east. Eastern North Dakota is overall flat, however, there are significant hills, most of the state is covered in grassland, crops cover most of eastern North Dakota but become increasingly sparse in the center and farther west. This diverse terrain supports nearly 2,000 species of plants, the state of North Dakota is home to the geographical center of North America located near Rugby, North Dakota North Dakota has a continental climate with hot summers and cold winters. The temperature differences are rather extreme because of its far inland position and being in the center of the Northern Hemisphere, with equal distances to the North Pole. As such, summers are almost subtropical in nature, but winters are cold enough to plant hardiness is very low. Native American peoples lived in what is now North Dakota for thousands of years before the coming of Europeans and their tribes included the Mandan people, the Dakota people and the Yanktonai, the latter two from the Lakota peoples. The first European to reach the area was the French-Canadian trader Pierre Gaultier, sieur de La Vérendrye, in 1762 the region became part of Spanish Louisiana until 1802. Dakota Territory was settled sparsely by European Americans until the late 19th century, with the advantage of grants of land, they vigorously marketed their properties, extolling the region as ideal for agriculture. An omnibus bill for statehood for North Dakota, South Dakota, Montana and his successor, Benjamin Harrison, signed the proclamations formally admitting North Dakota and South Dakota to the Union on November 2,1889

South Dakota is a state located in the Midwestern region of the United States. It is named after the Lakota and Dakota Sioux Native American tribes, South Dakota is the 17th most expansive, but the 5th least populous and the 5th least densely populated of the 50 United States. Once the southern portion of the Dakota Territory, South Dakota became a state on November 2,1889, Pierre is the state capital and Sioux Falls, with a population of about 171,000, is South Dakotas largest city. South Dakota is bordered by the states of North Dakota, Minnesota, Iowa, Nebraska, Wyoming, the state is bisected by the Missouri River, dividing South Dakota into two geographically and socially distinct halves, known to residents as East River and West River. Eastern South Dakota is home to most of the states population, West of the Missouri, ranching is the predominant agricultural activity, and the economy is more dependent on tourism and defense spending. Most of the Native American reservations are located in West River, the Black Hills, a group of low pine-covered mountains sacred to the Sioux, are located in the southwest part of the state. Mount Rushmore, a major tourist destination, is located there, South Dakota experiences a temperate continental climate, with four distinct seasons and precipitation ranging from moderate in the east to semi-arid in the west. The ecology of the state features species typical of a North American grassland biome, humans have inhabited the area for several millennia, with the Sioux becoming dominant by the early 19th century. In the late 19th century, European-American settlement intensified after a rush in the Black Hills. Encroaching miners and settlers triggered a number of Indian wars, ending with the Wounded Knee Massacre in 1890, historically dominated by an agricultural economy and a rural lifestyle, South Dakota has recently sought to diversify its economy in areas to attract and retain residents. South Dakotas history and rural character still strongly influence the culture of the state, South Dakota is situated in the north-central United States, and is considered a part of the Midwest by the U. S. Census Bureau, it is also part of the Great Plains region. The culture, economy, and geography of western South Dakota have more in common with the West than the Midwest, South Dakota has a total area of 77,116 square miles, making the state the 17th largest in the Union. Black Elk Peak, formerly named Harney Peak, with an elevation of 7,242 ft, is the states highest point, while the shoreline of Big Stone Lake is the lowest, with an elevation of 966 ft. South Dakota is bordered to the north by North Dakota, to the south by Nebraska, to the east by Iowa and Minnesota, the geographical center of the U. S. is 17 miles west of Castle Rock in Butte County. The North American continental pole of inaccessibility is located between Allen and Kyle,1,024 mi from the nearest coastline, the Missouri River is the largest and longest river in the state. Other major South Dakota rivers include the Cheyenne, James, Big Sioux, Eastern South Dakota has many natural lakes, mostly created by periods of glaciation. Additionally, dams on the Missouri River create four large reservoirs, Lake Oahe, Lake Sharpe, Lake Francis Case, South Dakota can generally be divided into three regions, eastern South Dakota, western South Dakota, and the Black Hills. The Missouri River serves as a boundary in terms of geographic, social, at times the Black Hills are combined with the rest of western South Dakota, and people often refer to the resulting two regions divided by the Missouri River as West River and East River

Colorado is a state in the United States encompassing most of the Southern Rocky Mountains as well as the northeastern portion of the Colorado Plateau and the western edge of the Great Plains. Colorado is part of the Western United States, the Southwestern United States, Colorado is the 8th most extensive and the 21st most populous of the 50 United States. The United States Census Bureau estimates that the population of Colorado was 5,540,545 on July 1,2016, the state was named for the Colorado River, which Spanish travelers named the Río Colorado for the ruddy silt the river carried from the mountains. The Territory of Colorado was organized on February 28,1861, Colorado is nicknamed the Centennial State because it became a state in the same year as the centennial of the United States Declaration of Independence. Colorado is noted for its landscape of mountains, forests, high plains, mesas, canyons, plateaus, rivers. Denver is the capital and the most populous city of Colorado, residents of the state are properly known as Coloradans, although the term Coloradoan has been used archaically and lives on in the title of Fort Collins newspaper, the Coloradoan. Colorado, Wyoming and Utah are the states which have boundaries defined solely by lines of latitude and longitude. The summit of Mount Elbert at 14,440 feet elevation in Lake County is the highest point in Colorado, Colorado is the only U. S. state that lies entirely above 1,000 meters elevation. The point where the Arikaree River flows out of Yuma County, Colorado and this point, which holds the distinction of being the highest low elevation point of any state, is higher than the high elevation points of 18 states and the District of Columbia. A little less than one half of the area of Colorado is flat, East of the Rocky Mountains are the Colorado Eastern Plains of the High Plains, the section of the Great Plains within Nebraska at elevations ranging from roughly 3,350 to 7,500 feet. The Colorado plains were mostly prairies, but they have many patches of forests, buttes. Eastern Colorado is presently covered in farmland and rangeland, along with small farming villages. Precipitation is fair, averaging from 15 to 25 inches annually, corn, wheat, hay, soybeans, and oats are all typical crops, and most of the villages and towns in this region boast both a water tower and a grain elevator. Irrigation water is available from the South Platte, the Arkansas River, and a few other streams, however, heavy use of ground water from wells for irrigation has caused underground water reserves to decline. As well as agriculture, eastern Colorado hosts considerable livestock, such as cattle ranches. Roughly 70% of Colorados population resides along the edge of the Rocky Mountains in the Front Range Urban Corridor between Cheyenne, Wyoming, and Pueblo, Colorado. This region is protected from prevailing storms that blow in from the Pacific Ocean region by the high Rockies in the middle of Colorado. The Front Range includes Denver, Boulder, Fort Collins, Loveland, Colorado Springs, Pueblo, Greeley and other townships, on the other side of the Rockies, the significant population centers in Western Colorado are the cities of Grand Junction, Durango, and Montrose

Montana /mɒnˈtænə/ is a state in the Western region of the United States. The states name is derived from the Spanish word montaña, Montana has several nicknames, although none official, including Big Sky Country and The Treasure State, and slogans that include Land of the Shining Mountains and more recently The Last Best Place. Montana has a 545-mile border with three Canadian provinces, British Columbia, Alberta, and Saskatchewan, the state to do so. It also borders North Dakota and South Dakota to the east, Wyoming to the south, Montana is ranked 4th in size, but 44th in population and 48th in population density of the 50 United States. The western third of Montana contains numerous mountain ranges, smaller island ranges are found throughout the state. In total,77 named ranges are part of the Rocky Mountains, the eastern half of Montana is characterized by western prairie terrain and badlands. The economy is based on agriculture, including ranching and cereal grain farming. Other significant economic activities include oil, gas, coal and hard rock mining, lumber, the health care, service, and government sectors also are significant to the states economy. Millions of tourists annually visit Glacier National Park, the Little Bighorn Battlefield National Monument, the name Montana comes from the Spanish word Montaña and the Latin word Montana, meaning mountain, or more broadly, mountainous country. Montaña del Norte was the name given by early Spanish explorers to the mountainous region of the west. The name was changed by Representatives Henry Wilson and Benjamin F. Harding, when Ashley presented a bill to establish a temporary government in 1864 for a new territory to be carved out of Idaho, he again chose Montana Territory. This time Rep. Samuel Cox, also of Ohio, objected to the name, Cox complained that the name was a misnomer given most of the territory was not mountainous and that a Native American name would be more appropriate than a Spanish one. Other names such as Shoshone were suggested, but it was decided that the Committee on Territories could name it whatever they wanted, with an area of 147,040 square miles, Montana is slightly larger than Japan. It is the fourth largest state in the United States after Alaska, Texas, and California, the largest landlocked U. S. state, and the worlds 56th largest national state/province subdivision. To the north, Montana shares a 545-mile border with three Canadian provinces, British Columbia, Alberta, and Saskatchewan, the state to do so. It borders North Dakota and South Dakota to the east, Wyoming to the south, the states topography is roughly defined by the Continental Divide, which splits much of the state into distinct eastern and western regions. Most of Montanas 100 or more named mountain ranges are in the western half. The Absaroka and Beartooth ranges in the states south-central part are part of the Central Rocky Mountains

New Mexico
–
New Mexico is a state located in the southwestern region of the United States of America. It was admitted to the Union as the 47th state on January 6,1912 and it is usually considered one of the Mountain States. New Mexico is fifth by area, the 36th-most populous, inhabited by Native Americans for thousands of years before European exploration, New Mexico was colonized by the Spanish in 1598 Imperial Spanish viceroyalty of New Spain. Later, it was part of independent Mexico before becoming a U. S. territory and eventually a U. S. state as a result of the Mexican–American War. Among U. S. states, New Mexico has the highest percentage of Hispanics, the major Native American nations in the state are Navajo, Pueblo, and Apache peoples. The demography and culture of the state are shaped by these strong Hispanic and Native American influences and its scarlet and gold colors are taken from the royal standards of Spain, along with the ancient sun symbol of the Zia, a Pueblo-related tribe. New Mexico, or Nuevo México in Spanish, is incorrectly believed to have taken its name from the nation of Mexico. The name simply stuck, even though the area had no connection to Mexico or the Mexica Indian tribes, Mexico, formerly a part of New Spain, adopted its name centuries later in 1821, after winning independence from Spanish rule. New Mexico was a part of the independent Mexican Empire and Federal Republic of Mexico for 27 years,1821 through 1848, New Mexico and Mexico developed as neighboring Spanish-speaking communities under Spanish rule, with relatively independent histories. The states total area is 121,412 square miles, the eastern border of New Mexico lies along 103° W longitude with the state of Oklahoma, and 2.2 miles west of 103° W longitude with Texas. On the southern border, Texas makes up the eastern two-thirds, while the Mexican states of Chihuahua and Sonora make up the western third, the western border with Arizona runs along the 109°03 W longitude. The southwestern corner of the state is known as the Bootheel, the 37° N latitude parallel forms the northern boundary with Colorado. The states New Mexico, Colorado, Arizona, and Utah come together at the Four Corners in the corner of New Mexico. New Mexico, although a state, has very little water. Its surface water area is about 250 square miles, the New Mexican landscape ranges from wide, rose-colored deserts to broken mesas to high, snow-capped peaks. Despite New Mexicos arid image, heavily forested mountain wildernesses cover a significant portion of the state, the Sangre de Cristo Mountains, the southernmost part of the Rocky Mountains, run roughly north-south along the east side of the Rio Grande in the rugged, pastoral north. The most important of New Mexicos rivers are the Rio Grande, Pecos, Canadian, San Juan, the Rio Grande is tied for the fourth-longest river in the United States. Tourists visiting these sites bring significant money to the state, other areas of geographical and scenic interest include Kasha-Katuwe Tent Rocks National Monument and the Gila Wilderness in the southwest of the state

Oklahoma
–
Oklahoma is a state located in the South Central United States. Oklahoma is the 20th-most extensive and the 28th-most populous of the 50 United States, the states name is derived from the Choctaw words okla and humma, meaning red people. The name was settled upon statehood, Oklahoma Territory and Indian Territory were merged, on November 16,1907, Oklahoma became the 46th state to enter the union. Its residents are known as Oklahomans, or informally Okies, and its capital, a major producer of natural gas, oil, and agricultural products, Oklahoma relies on an economic base of aviation, energy, telecommunications, and biotechnology. In 2007, it had one of the economies in the United States, ranking among the top states in per capita income growth. Oklahoma City and Tulsa serve as Oklahomas primary economic anchors, with nearly two-thirds of Oklahomans living within their metropolitan statistical areas. With small mountain ranges, prairie, mesas, and eastern forests, most of Oklahoma lies in the Great Plains, Cross Timbers, interior Highlands—a region especially prone to severe weather. The name Oklahoma comes from the Choctaw phrase okla humma, literally meaning red people, equivalent to the English word Indian, okla humma was a phrase in the Choctaw language used to describe Native American people as a whole. Oklahoma later became the de facto name for Oklahoma Territory, and it was approved in 1890. Oklahoma is the 20th-largest state in the United States, covering an area of 69,898 square miles and it is one of six states on the Frontier Strip and lies partly in the Great Plains near the geographical center of the 48 contiguous states. It is bounded on the east by Arkansas and Missouri, on the north by Kansas, on the northwest by Colorado, on the far west by New Mexico, much of its border with Texas lies along the Southern Oklahoma Aulacogen, a failed continental rift. The geologic figure defines the placement of the Red River, the Oklahoma panhandles Western edge is out of alignment with its Texas border. The Oklahoma/New Mexico border is actually 2.1 to 2.2 miles east of the Texas line, the border between Texas and New Mexico was set first as a result of a survey by Spain in 1819. It was then set along the 103rd Meridian, in the 1890s, when Oklahoma was formally surveyed using more accurate surveying equipment and techniques, it was discovered the Texas line was not set along the 103rd Meridian. Surveying techniques were not as accurate in 1819, and the actual 103rd Meridian was approximately 2.2 miles to the east and it was much easier to leave the mistake than for Texas to cede land to New Mexico to correct the surveying error. The placement of the Oklahoma/New Mexico border represents the true 103rd Meridian, cimarron County in Oklahomas panhandle is the only county in the United States that touches four other states, New Mexico, Texas, Colorado and Kansas. Its highest and lowest points follow this trend, with its highest peak, Black Mesa, at 4,973 feet above sea level, situated near its far northwest corner in the Oklahoma Panhandle. The states lowest point is on the Little River near its far southeastern boundary near the town of Idabel, Oklahoma, which dips to 289 feet above sea level

Texas is the second largest state in the United States by both area and population. Other major cities include Austin, the second most populous state capital in the U. S. Texas is nicknamed the Lone Star State to signify its former status as an independent republic, and as a reminder of the states struggle for independence from Mexico. The Lone Star can be found on the Texan state flag, the origin of Texass name is from the word Tejas, which means friends in the Caddo language. Due to its size and geologic features such as the Balcones Fault, although Texas is popularly associated with the U. S. southwestern deserts, less than 10 percent of Texas land area is desert. Most of the centers are located in areas of former prairies, grasslands, forests. Traveling from east to west, one can observe terrain that ranges from coastal swamps and piney woods, to rolling plains and rugged hills, the term six flags over Texas refers to several nations that have ruled over the territory. Spain was the first European country to claim the area of Texas, Mexico controlled the territory until 1836 when Texas won its independence, becoming an independent Republic. In 1845, Texas joined the United States as the 28th state, the states annexation set off a chain of events that caused the Mexican–American War in 1846. A slave state before the American Civil War, Texas declared its secession from the U. S. in early 1861, after the Civil War and the restoration of its representation in the federal government, Texas entered a long period of economic stagnation. One Texan industry that thrived after the Civil War was cattle, due to its long history as a center of the industry, Texas is associated with the image of the cowboy. The states economic fortunes changed in the early 20th century, when oil discoveries initiated a boom in the state. With strong investments in universities, Texas developed a diversified economy, as of 2010 it shares the top of the list of the most Fortune 500 companies with California at 57. With a growing base of industry, the leads in many industries, including agriculture, petrochemicals, energy, computers and electronics, aerospace. Texas has led the nation in export revenue since 2002 and has the second-highest gross state product. The name Texas, based on the Caddo word tejas meaning friends or allies, was applied by the Spanish to the Caddo themselves, during Spanish colonial rule, the area was officially known as the Nuevo Reino de Filipinas, La Provincia de Texas. Texas is the second largest U. S. state, behind Alaska, though 10 percent larger than France and almost twice as large as Germany or Japan, it ranks only 27th worldwide amongst country subdivisions by size. If it were an independent country, Texas would be the 40th largest behind Chile, Texas is in the south central part of the United States of America.

Southwestern Wyoming was included in the Spanish Empire and then Mexican territory until it was ceded to the United States in 1848 at the end of the Mexican–American War. The region acquired the name Wyoming when a bill was introduced to Congress in 1865 to provide a government for the territory of Wyoming. The territory was named after the Wyoming Valley in Pennsylvania, with the name ultimately being derived from the Munsee word xwé, wamənk, the mineral extraction industry—especially coal, oil, natural gas, and trona—along with the travel and tourism sector are the main drivers behind Wyomings economy. Agriculture has historically been an important component of the economy with the main commodities being livestock, hay, sugar beets, grain. The climate is generally semi-arid and continental, being drier and windier in comparison to the rest of the United States, except for the 1964 election, Wyoming has been a politically conservative state since the 1950s, with the Republican party winning every presidential election. Wyoming is one of three states to have borders along only straight latitudinal and longitudinal lines, rather than being defined by natural landmarks. Wyoming is bordered on the north by Montana, on the east by South Dakota and Nebraska, on the south by Colorado, on the southwest by Utah, and on the west by Idaho. It is the tenth largest state in the United States in total area, from the north border to the south border it is 276 miles, and from the east to the west border is 365 miles at its south end and 342 miles at the north end.

Provinces and territories of Canada
–
Canadas geography is divided into administrative divisions known as provinces and territories that are responsible for delivery of sub-national governance. Over its history, Canadas international borders have changed several times, the ten provinces are Alberta, British Columbia, Manitoba, New Brunswick, Newfoundland and Labrador, Nova Scotia, Ontario, Prince Edward Island, Quebec, and Saskatchewan. Several of the provinces were former British colonies, Quebec was originally a French colony, the three territories are Northwest Territories, Nunavut, and Yukon, which govern the rest of the area of the former British North America. Together, the provinces and territories make up the worlds second-largest country by area, the powers flowing from the Constitution Act are divided between the federal government and the provincial governments to exercise exclusively. In modern Canadian constitutional theory, the provinces are considered to be co-sovereign divisions, the territories are not sovereign, but simply part of the federal realm, and have a commissioner who represents the federal government. Notes, There are three territories in Canada, unlike the provinces, the territories of Canada have no inherent sovereignty and have only those powers delegated to them by the federal government. They include all of mainland Canada north of latitude 60° north and west of Hudson Bay, the following table lists the territories in order of precedence. Prior to Confederation, Ontario and Quebec were united as the Province of Canada, over the following years, Manitoba, British Columbia, and Prince Edward Island were added as provinces. The Hudsons Bay Company controlled large swathes of western Canada referred to as Ruperts Land and the North-Western Territory until 1870, subsequently, the area was re-organized into the province of Manitoba and the Northwest Territories. The remaining Arctic islands were transferred by Britain to Canada in 1880,1898 saw the Yukon Territory, later renamed simply as Yukon, carved from the parts of the Northwest Territories surrounding the Klondike gold fields. On September 1,1905, a portion of the Northwest Territories south of the 60th parallel north became the provinces of Alberta and Saskatchewan. In 1912, the boundaries of Quebec, Ontario and Manitoba were expanded northward, Manitobas to the 60° parallel, Ontarios to Hudson Bay, in 1907, Newfoundland acquired dominion status. In the middle of the Great Depression in Canada with Newfoundland facing a period of economic crisis. In 2001, it was officially renamed Newfoundland and Labrador, in 1903, the Alaska Panhandle Dispute fixed British Columbias northwestern boundary. This was one of two provinces in Canadian history to have its size reduced. In 1999, Nunavut was created from the portion of the Northwest Territories. Yukon lies in the portion of The North, while Nunavut is in the east. All three territories combined are the most sparsely populated region in Canada, covering 3,921,739 km2 in land area and they are often referred to as a single region, The North, for organisational and economic purposes

The province extends 1,223 km north to south and 660 km east to west at its maximum width, with the exception of the semi-arid steppe of the south-eastern section, the province has adequate water resources. There are numerous rivers and lakes used for swimming, fishing, there are three large lakes, Lake Claire in Wood Buffalo National Park, Lesser Slave Lake, and Lake Athabasca which lies in both Alberta and Saskatchewan. The longest river in the province is the Athabasca River which travels 1,538 km from the Columbia Icefield in the Rocky Mountains to Lake Athabasca, the largest river is the Peace River with an average flow of 2161 m3/s. The Peace River originates in the Rocky Mountains of northern British Columbia and flows through northern Alberta and into the Slave River, Albertas capital city, Edmonton, is located approximately in the geographic centre of the province. It is the most northerly city in Canada, and serves as a gateway. The region, with its proximity to Canadas largest oil fields, has most of western Canadas oil refinery capacity, Calgary is located approximately 280 km south of Edmonton and 240 km north of Montana, surrounded by extensive ranching country. Almost 75% of the population lives in the Calgary–Edmonton Corridor. The land grant policy to the served as a means to populate the province in its early years

Manitoba
–
Manitoba is a province at the longitudinal centre of Canada. It is one of the three provinces and Canadas fifth-most populous province with its estimated 1.3 million people. Manitoba covers 649,950 square kilometres with a varied landscape. Aboriginal peoples have inhabited what is now Manitoba for thousands of years, in the late 17th century, fur traders arrived in the area when it was part of Ruperts Land and owned by the Hudsons Bay Company. In 1869, negotiations for the creation of the province of Manitoba led to an uprising of the Métis people against the Government of Canada. The rebellions resolution led to the Parliament of Canada passing the Manitoba Act in 1870 that created the province, Manitobas capital and largest city, Winnipeg, is Canadas eighth-largest census metropolitan area. Winnipeg is the seat of government, home to the Legislative Assembly of Manitoba, four of the provinces five universities and all four of its professional sports teams are in Winnipeg. The name Manitoba is believed to be derived from the Cree, the name derives from Cree manitou-wapow or Ojibwa manidoobaa, both meaning straits of Manitou, the Great Spirit, a place referring to what are now called The Narrows in the centre of Lake Manitoba. It may also be from the Assiniboine for Lake of the Prairie, the lake was known to French explorers as Lac des Prairies. Thomas Spence chose the name to refer to a new republic he proposed for the south of the lake. Métis leader Louis Riel also chose the name, and it was accepted in Ottawa under the Manitoba Act of 1870 and it adjoins Hudson Bay to the northeast, and is the only prairie province to have a saltwater coastline. The Port of Churchill is Canadas only Arctic deep-water port and the shortest shipping route between North America and Asia, Lake Winnipeg is the tenth-largest freshwater lake in the world. Hudson Bay is the worlds second-largest bay, Manitoba is at the heart of the giant Hudson Bay watershed, once known as Ruperts Land. It was a area of the Hudsons Bay Company, with many rivers. The province has a saltwater coastline bordering Hudson Bay and more than 110,000 lakes, Manitobas major lakes are Lake Manitoba, Lake Winnipegosis, and Lake Winnipeg, the tenth-largest freshwater lake in the world. Some traditional Native lands and boreal forest on Lake Winnipegs east side are a proposed UNESCO World Heritage Site. Manitoba is at the centre of the Hudson Bay drainage basin, with a volume of the water draining into Lake Winnipeg. This basins rivers reach far west to the mountains, far south into the United States, major watercourses include the Red, Assiniboine, Nelson, Winnipeg, Hayes, Whiteshell and Churchill rivers

Saskatchewan
–
Saskatchewan is a prairie and boreal province in west-central Canada, the only province without natural borders. It has an area of 651,900 square kilometres, nearly 10 percent of which is water, composed mostly of rivers, reservoirs. As of December 2013, Saskatchewans population was estimated at 1,114,170, residents primarily live in the southern prairie half of the province, while the northern boreal half is mostly forested and sparsely populated. Of the total population, roughly half live in the provinces largest city, Saskatoon, or the provincial capital, other notable cities include Prince Albert, Moose Jaw, Yorkton, Swift Current, North Battleford, and the border city Lloydminster. Saskatchewan is a province with large distances to moderating bodies of waters. As a result, its climate is continental, rendering severe winters throughout the province. Southern areas have very warm or hot summers, Midale and Yellow Grass near the U. S. border are tied for the highest ever recorded temperatures in Canada with 45 °C observed at both locations on July 5,1937. In winter, temperatures below −45 °C are possible even in the south during extreme cold snaps, Saskatchewan has been inhabited for thousands of years by various indigenous groups, and first explored by Europeans in 1690 and settled in 1774. It became a province in 1905, carved out from the vast North-West Territories, in the early 20th century the province became known as a stronghold for Canadian social democracy, North Americas first social-democratic government was elected in 1944. The provinces economy is based on agriculture, mining, and energy, Saskatchewans current premier is Brad Wall and its lieutenant-governor is Vaughn Solomon Schofield. In 1992, the federal and provincial governments signed a land claim agreement with First Nations in Saskatchewan. The First Nations received compensation and were permitted to buy land on the market for the tribes, they have acquired about 3,079 square kilometres. Some First Nations have used their settlement to invest in urban areas and its name derived from the Saskatchewan River. The river was known as kisiskāciwani-sīpiy in the Cree language, as Saskatchewans borders largely follow the geographic coordinates of longitude and latitude, the province is roughly a quadrilateral, or a shape with four sides. However the 49th parallel boundary and the 60th northern border appear curved on globes, additionally, the eastern boundary of the province is partially crooked rather than following a line of longitude, as correction lines were devised by surveyors prior to the homestead program. S. States of Montana and North Dakota, Saskatchewan has the distinction of being the only Canadian province for which no borders correspond to physical geographic features. Along with Alberta, Saskatchewan is one of only two land-locked provinces, the overwhelming majority of Saskatchewans population is located in the southern third of the province, south of the 53rd parallel. Saskatchewan contains two natural regions, the Canadian Shield in the north and the Interior Plains in the south

Ranch
–
A ranch is an area of land, including various structures, given primarily to the practice of ranching, the practice of raising grazing livestock such as cattle or sheep for meat or wool. The word most often applies to livestock-raising operations in Mexico, the Western United States and Canada, people who own or operate a ranch are called ranchers, cattlemen, or stockgrowers. Ranching is also a used to raise less common livestock such as elk, American bison or even ostrich, emu. Ranches generally consist of areas, but may be of nearly any size. In the western United States, many ranches are a combination of owned land supplemented by grazing leases on land under the control of the federal Bureau of Land Management. If the ranch includes arable or irrigated land, the ranch may also engage in an amount of farming, raising crops for feeding the animals, such as hay. Ranches that cater exclusively to tourists are called guest ranches or, colloquially, most working ranches do not cater to guests, though they may allow private hunters or outfitters onto their property to hunt native wildlife. Ranching is part of the iconography of the Wild West as seen in Western movies, the person who owns and manages the operation of a ranch is usually called a rancher, but the terms cattleman, stockgrower, or stockman are also sometimes used. If this individual in charge of management is an employee of the actual owner. A rancher who primarily raises young stock sometimes is called an operator or a cow-calf man. This person is usually the owner, though in cases, particularly where there is absentee ownership. The people who are employees of the rancher and involved in handling livestock are called a number of terms, including cowhand, ranch hand, people exclusively involved with handling horses are sometimes called wranglers. Ranching and the tradition originated in Spain, out of the necessity to handle large herds of grazing animals on dry land from horseback. During the Reconquista, members of the Spanish nobility and various military orders received large land grants that the Kingdom of Castile had conquered from the Moors and these landowners were to defend the lands put into their control and could use them for earning revenue. When the Conquistadors came to the Americas in the 16th century, followed by settlers, they brought their cattle, huge land grants by the Spanish government, part of the hacienda system, allowed large numbers of animals to roam freely over vast areas. A number of different traditions developed, often related to the location in Spain from which a settlement originated. For example, many of the traditions of the Jalisco charros in central Mexico come from the Salamanca charros of Castile, however, there were cattle on the eastern seaboard. Deep Hollow Ranch,110 miles east of New York City in Montauk, New York, claims to be the first ranch in the United States, the prairie and desert lands of what today is Mexico and the western United States were well-suited to open range grazing

Dryland farming
–
Dryland farming and dry farming are agricultural techniques for non-irrigated cultivation of crops. Dryland farming is associated with drylands - dry areas characterized by a wet season followed by a warm dry season. Dryland farming was introduced to southern Russia and Ukraine by Ukrainian Mennonites under the influence of Johann Cornies, in Australia, it is widely practiced in all states but the Northern Territory. Dry farming may be practiced in areas that have significant annual rainfall during a wet season, Crops are cultivated during the subsequent dry season, using practices that make use of the stored moisture in the soil. California, Colorado and Oregon, in the United States, are three states where dry farming is practiced for a variety of crops, Dryland farmed crops may include winter wheat, corn, beans, Sunflowers or even watermelon. Successful dryland farming is possible with as little as 9 inches of precipitation a year, native American tribes in the arid Southwest survived for hundreds of years on dryland farming in areas with less than 10 inches of rain. The choice of crop is influenced by the timing of the predominant rainfall in relation to the seasons. For example, winter wheat is more suited to regions with higher winter rainfall areas with summer wet seasons may be more suited to summer growing crops such as sorghum. Dry farmed crops may include grapes, tomatoes, pumpkins, beans and these crops grow using the winter water stored in the soil, rather than depending on rainfall during the growing season. Dryland farming has evolved as a set of techniques and management practices used by farmers to adapt to the presence or lack of moisture in a given crop cycle. In marginal regions, a farmer should be able to survive occasional crop failures. Survival as a dryland farmer requires careful husbandry of the moisture available for the crop, Dryland farming involves the constant assessing of the amount of moisture present or lacking for any given crop cycle and planning accordingly. Dryland farmers know that to be successful they have to be aggressive during the good years in order to offset the dry years. The fact that a period must be included in the crop rotation means that fields cannot always be protected by a cover crop. Some of the theories of dryland farming developed in the late 19th and early 20th centuries claimed to be scientific but were in reality pseudoscientific, Dry farming depends on making the best use of the bank of soil moisture that was created by winter rainfall. Some dry farming practices include, Wider than normal spacing, to provide a bank of moisture for each plant. Strict weed control, to ensure that weeds do not consume soil moisture needed by the cultivated plants, cultivation of soil to produce a dust mulch, thought to prevent the loss of water through capillary action. This practice is controversial, and is not universally advocated, selection of crops and cultivars suited for dry farming practices

Canadian Prairies
–
The Canadian Prairies is a region in western Canada, which may correspond to several different definitions, natural or political. Notably, the Prairie provinces or simply the Prairies comprise the provinces of Alberta, Saskatchewan, in a more restricted sense, the term may also refer only to the areas of those provinces covered by prairie, their portions of the physiographic region known as the Interior Plains. Prairie also covers portions of northeastern British Columbia, though that province is not included in the region in a political sense. Northern short grasslands in southeastern Alberta and southwestern Saskatchewan, northern tall grasslands in southern Manitoba, and Aspen parkland, which covers central Alberta, central Saskatchewan, and southern Manitoba. The Prairie starts from north of Edmonton, it covers the three provinces east to the Manitoba-Minnesota border, the Canadian prairies typically experience about 12 to 15 in of annual precipitation in the semi-arid areas while they experience 16 to 20 in in the continental regions. Manitoba is generally the coldest and most humid of the three prairie provinces, the area is also prone to thunderstorms in the spring and summer. Some of these storms, especially further south, are enough for tornadoes. The plains comprise both prairies and forests while, with the exception of Arctic tundra along the Hudson Bay, three main grassland types occur in the Canadian prairies, tallgrass prairie, mixed grass prairie, and fescue prairie. Each has a geographic distribution and characteristic mix of plant species. All but a fraction of one percent of the tallgrass prairie has been converted to cropland, what remains occurs on the 6,000 km2 plain centred in the Red River Valley in Manitoba. Mixed prairie is more common and is part of the dry plains that extend from Canada south to the U. S. state of Texas. More than half of the native grassland in the Canadian prairies is mixed. Though widespread in southern Saskatchewan and southeastern Alberta, because of extensive cattle grazing, fescue prairie occurs in the moister regions, occupying the northern extent of the prairies in central and southwestern Alberta and west-central Saskatchewan. The southwestern Canadian prairies, supporting brown and black soil types, are semi-arid and highly prone to frequent, the zones around the cities of Regina and immediately east of Calgary are also very dry. Most heavy precipitation quickly dissipates by the time it passes Cheadle on its way heading east, in an average year, southern Saskatchewan receives between 30–51 cm of precipitation, with the majority falling between April and June. Frost from October to April limits the growing season for certain crops, the eastern section of the Canadian prairies in Manitoba is well watered with several large lakes such as Lake Winnipeg and several large rivers. The area also gets reasonable amounts of precipitation, the middle sections of Alberta and Saskatchewan are also wetter than the south and have better farmland, despite having a shorter frost-free season. The areas around Edmonton and Saskatoon are especially notable as good farmland, both lie in the northern area of the Pallisers Triangle, and are within aspen parkland a transitional prairie ecozone

Interior Plains
–
The Interior Plains is a vast physiographic region that spreads across the Laurentian craton of central North America. The region extends from the Gulf Coast region to the Arctic Ocean along the east flank of the Rocky Mountains, in Canada the region separates the Rocky Mountains from the Canadian Shield. In the United States the plains include the Great Plains of the west and this area was originally formed when cratons collided and welded together 1. 8–1.9 billion years ago in the Trans-Hudson orogeny during the Paleoproterozoic Era. Precambrian metamorphic and igneous rocks now form the basement of the Interior Plains, with the exception of the Black Hills of South Dakota, the entire region has low relief, reflecting more than 500 million years of relative tectonic stability. The Interior plains region of the United States and Canada falls within this area, the Interior Plains were often covered by shallow inland seas. Sediments from the shield and the Rocky Mountains were deposited in these seas over millions of years, eventually the sediments were compressed by the weight of the layers above into sedimentary rock. Part of the sedimentary rock deposited in these areas consists of reefs that formed close to the surface of seas during the Paleozoic Era. During much of the Mesozoic Era, the North American continental interior were mostly well above sea level, the Interior Plains continued to receive deposits from the eroding Rocky Mountains to the west and Appalachian and Ozark/Ouachita Mountains to the east and south throughout the era. The flatness of the Interior Plains is a reflection of the platform of mostly flat-lying marine, USGS map showing the subdivisions of the Interior Plains Province within the US

Plains Indians
–
Plains Indians are usually divided into two broad classifications which overlap to some degree. The first group became a nomadic horse culture during the 18th and 19th centuries, following the vast herds of buffalo. These include the Blackfoot, Arapaho, Assiniboine, Cheyenne, Comanche, Crow, Gros Ventre, Kiowa, Lakota, Lipan, Plains Apache, Plains Cree, Plains Ojibwe, Sarsi, Nakoda, and Tonkawa. The second group of Plains Indians were semi-sedentary, and, in addition to hunting buffalo, they lived in villages, raised crops, and actively traded with other tribes. These include the Arikara, Hidatsa, Iowa, Kaw, Kitsai, Mandan, Missouria, Omaha, Osage, Otoe, Pawnee, Ponca, Quapaw, Wichita, and the Santee Dakota, Yanktonai and Yankton Dakota. Both groups included people indigenous to the region as well as those who were pushed west by population pressure linked to the expansion of white culture. Indigenous peoples of the Great Plains are often separated into Northern and Southern Plains tribes, the tribes followed the seasonal grazing and migration of buffalo. The Plains Indians lived in teepees because they were disassembled and allowed the nomadic life of following game. When horses were obtained, the Plains tribes rapidly integrated them into their daily lives, people in the southwest began to acquire horses in the 16th century by trading or stealing them from Spanish colonists in New Mexico. As horse culture moved northward, the Comanche were among the first to commit to a fully mounted nomadic lifestyle and this occurred by the 1730s, when they had acquired enough horses to put all their people on horseback. The Spanish explorer Francisco Vásquez de Coronado was the first European to describe the Plains Indian culture, while searching for a reputedly wealthy land called Quivira in 1541, Coronado came across the Querechos in the Texas panhandle. The Querechos were the later called Apache. According to the Spaniards, the Querechos lived in tents made of the skins of the cows. They empty a large gut and fill it with blood, Coronado described many common features of Plains Indians culture, skin tepees, travois pulled by dogs, Plains Indian Sign Language, and staple foods such as jerky and pemmican. The Plains Indians found by Coronado had not yet obtained horses, by the 19th century, the typical year of the Lakota and other northern nomads was a communal buffalo hunt as early in spring as their horses had recovered from the rigors of the winter. In June and July the scattered bands of the gathered together into large encampments. These gatherings afforded leaders to meet to make decisions, plan movements, arbitrate disputes. In the fall, people would split up into smaller bands to facilitate hunting to procure meat for the long winter, between the fall hunt and the onset of winter was a time when Lakota warriors could undertake raiding and warfare

Natural Resources Canada
–
It was created in 1995 by amalgamating the now-defunct Departments of Energy, Mines and Resources and Forestry. Natural Resources Canada works to ensure the development of Canadas natural resources, including energy, forests. NRCan also uses its expertise in earth sciences to build and maintain a knowledge base of our landmass. To promote internal collaboration, NRCan has implemented a departmental wide wiki based on MediaWiki, under the Canadian constitution, responsibility for natural resources belongs to the provinces, not the federal government. However, the government has jurisdiction over off-shore resources, trade and commerce in natural resources, statistics, international relations. The current Minister of Natural Resources is Jim Carr as of November 4,2015, the department is governed by the Resources and Technical Surveys Act, R. S. C. C. R-7 and the Department of Natural Resources Act, S. C, structured along business lines according to types of natural resources and areas of interest

Ecoregion
–
An ecoregion is an ecologically and geographically defined area that is smaller than a bioregion, which in turn is smaller than an ecozone. All three of these are less or greater than an ecosystem. Ecoregions cover relatively large areas of land or water, and contain characteristic, the biodiversity of flora, fauna and ecosystems that characterise an ecoregion tends to be distinct from that of other ecoregions. Three caveats are appropriate for all bio-geographic mapping approaches, firstly, no single bio-geographic framework is optimal for all taxa. Ecoregions reflect the best compromise for as many taxa as possible, secondly, ecoregion boundaries rarely form abrupt edges, rather, ecotones and mosaic habitats bound them. Thirdly, most ecoregions contain habitats that differ from their assigned biome, biogeographic provinces may originate due to various barriers. Some physical, some climatic and some ocean chemical related, the history of the term is somewhat vague as it was used in many contexts, forest classifications, biome classifications, biogeographic classifications, etc. The concept of ecoregion of Bailey gives more importance to ecological criteria, while the WWF concept gives more importance to biogeography, there is significant, but not absolute, spatial correlation among these characteristics, making the delineation of ecoregions an imperfect science. Such transition zones are called ecotones, Ecoregions can be categorized using an algorithmic approach or a holistic, “weight-of-evidence” approach where the importance of various factors may vary. An example of the approach is Robert Bailey’s work for the U. S. The intended purpose of ecoregion delineation may affect the method used, according to WWF, the boundaries of an ecoregion approximate the original extent of the natural communities prior to any major recent disruptions or changes. WWF has identified 867 terrestrial ecoregions, and approximately 450 freshwater ecoregions across the Earth, the use of the term ecoregion is an outgrowth of a surge of interest in ecosystems and their functioning. In particular, there is awareness of issues relating to spatial scale in the study and it is widely recognized that interlinked ecosystems combine to form a whole that is greater than the sum of its parts. The Global 200 is the list of ecoregions identified by WWF as priorities for conservation, Terrestrial ecoregions are land ecoregions, as distinct from freshwater and marine ecoregions. In this context, terrestrial is used to mean of land, WWF ecologists currently divide the land surface of the Earth into 8 major ecozones containing 867 smaller terrestrial ecoregions. The WWF effort is a synthesis of previous efforts to define. Many consider this classification to be decisive, and some propose these as stable borders for bioregional democracy initiatives. The eight terrestrial ecozones follow the major floral and faunal boundaries, identified by botanists and zoologists, ecozone boundaries generally follow continental boundaries, or major barriers to plant and animal distribution, like the Himalayas and the Sahara

Haskell County, Kansas
–
Haskell County is a county located in the U. S. state of Kansas. As of the 2010 census, the county population was 4,256 and its county seat and most populous city is Sublette. Haskell County was founded in 1887 and it was named for Dudley C. Haskell, a member of Congress. John M. Dr. Loring Miner, a Haskell County doctor, Public Health Service about the new and more deadly variant of the virus. It produced the common influenza symptoms with a new intensity, violent headache and body aches, high fever and this was violent, rapid in its progress through the body, and sometimes lethal. Soon dozens of patients—the strongest, the healthiest, the most robust people in the county—were being struck down as suddenly as if they had been shot. Barry writes that In the first six months of 1918, Miners warning of influenza of a type was the only reference in that journal to influenza anywhere in the world. Haskell County was one of the hardest hit counties in the Midwest during the drought of 1930-1937, the first rodeo and fair was held in Sublette in 1916 and the fair continues at the same location. The first school district was founded in Santa Fe in 1887, watkins, who owned a considerable amount of land in the county, was named World Wheat Queen in 1926. According to the U. S. Census Bureau, the county has an area of 578 square miles. Haskell County is the flattest county in Kansas, the population density was 8 people per square mile. There were 1,639 housing units at a density of 3 per square mile.

Buffalo wallow
–
A buffalo wallow or bison wallow is a natural topographical depression in the flat prairie land that holds rain water and runoff. Originally this would have served as a watering hole for wildlife. Wallowing buffalo that drank from and bathed in these naturally occurring shallow water holes gradually changed the pristine watering hole into a buffalo wallow, each time they went away, they carried mud with them from the hole, thus enlarging the wallow. Furthermore, wallowing action caused abrasion of hair, natural oils and cellular debris from their hides and left the debris in the water. Ultimately the water remained for long periods which attracted more wildlife, even when stagnant, the water would be eagerly drunk by thirsty animals. Though thriving buffalo herds roamed and grazed the great prairies of North America for thousands of years, exceptions are the somewhat rare yet still visible ancient buffalo wallows found occasionally on the North American prairie flatlands. Buffalo wallows are also made by the Asian water buffalo and the African buffalo

American bison
–
The American bison, also commonly known as the American buffalo or simply buffalo, is a North American species of bison that once roamed the grasslands of North America in massive herds. Bison were seen in North Carolina near Buffalo Ford on the Catawba River as late as 1750. Two subspecies or ecotypes have been described, the bison, smaller in size and with a more rounded hump. Furthermore, the bison has been suggested to consist of a northern. However, this is not supported. The wood bison is one of the largest wild species of bovid in the world, surpassed by only the Asian gaur and it is the largest extant land animal in the Americas. The American bison is the mammal of the United States. The term buffalo is considered to be a misnomer for this animal, and could be confused with true buffalos, the Asian water buffalo. The name buffalo is listed in dictionaries as an acceptable name for American buffalo or bison. In reference to animal, the term buffalo dates to 1625 in North American usage when the term was first recorded for the American mammal. It thus has a longer history than the term bison. The American bison is very related to the wisent or European bison. In Plains Indian languages in general, male and female buffaloes are distinguished, a bison has a shaggy, long, dark-brown winter coat, and a lighter-weight, lighter-brown summer coat. As is typical in ungulates, the bison is slightly larger than the female and, in some cases. Plains bison are often in the range of sizes. Head-and-body lengths range from 2 to 3.5 m long, shoulder heights in the species can range from 152 to 186 cm. Weights can range from 318 to 1,000 kg Mature bulls tend to be larger than cows. Cow weights have had reported medians of 450 to 495 kg, with one small sample averaging 479 kg, the heaviest wild bull ever recorded weighed 1,270 kg

High Plains (United States)
–
The southern region of the Western High Plains ecology region contains the geological formation known as Llano Estacado which can be seen from a short distance or from miles away on satellite maps. From east to west, the High Plains rise in elevation from around 1,160 feet to over 7,800 feet. The term Great Plains, for the region west of about the 96th or 98th meridian, nevin Fennemans 1916 study, Physiographic Subdivision of the United States, brought the term Great Plains into more widespread usage. Prior to 1916, the region was almost invariably called the High Plains, today the term High Plains is usually used for a subregion instead of the whole of the Great Plains. The High Plains has a cold semi-arid climate—Köppen BSk—receiving between 10–20 inches of precipitation annually, due to low moisture and high elevation, the High Plains commonly experiences wide ranges and extremes in temperature. This is the record for the greatest temperature change in 24 hours. The region is known for the steady, and sometimes intense, the winds add a considerable wind chill factor in the winter. The development of farms in the High Plains is one of the newest areas of economic development. The High Plains are anomalously high in elevation, an explanation has recently been proposed to explain this high elevation. As the Farallon plate was subducted into the mantle beneath the region, within the crust this water caused the hydration of dense garnet and other phases into lower density amphibole and mica minerals. The resulting increase in crustal volume raised the elevation about one mile, plants endemic to the region are shortgrass prairie, prickly pear cacti and scrub. Agriculture in the forms of ranching and the growing of wheat, corn. Some areas of the High Plains have significant petroleum and natural gas deposits, the combination of oil, natural gas, and wind energy along with plentiful underground water, has allowed some areas to sustain a range of economic activity, including occasional industry. For example, the ASARCO refinery in Amarillo, Texas has been in operation since 1924 due to the plentiful and inexpensive natural gas and water that are needed in metal ore refining. The High Plains has one of the lowest population densities of any region in the continental United States, Wyoming, smaller towns, on the other hand, often struggle to sustain their population.

North America
–
North America is a continent entirely within the Northern Hemisphere and almost all within the Western Hemisphere. It can also be considered a subcontinent of the Americas. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the west and south by the Pacific Ocean, and to the southeast by South America and the Caribbean Sea. North America covers an area of about 24,709,000 square kilometers, about 16. 5% of the land area. North America is the third largest continent by area, following Asia and Africa, and the fourth by population after Asia, Africa, and Europe. In 2013, its population was estimated at nearly 565 million people in 23 independent states, or about 7. 5% of the worlds population, North America was reached by its first human populations during the last glacial period, via crossing the Bering land bridge. The so-called Paleo-Indian period is taken to have lasted until about 10,000 years ago, the Classic stage spans roughly the 6th to 13th centuries. The Pre-Columbian era ended with the migrations and the arrival of European settlers during the Age of Discovery. Present-day cultural and ethnic patterns reflect different kind of interactions between European colonists, indigenous peoples, African slaves and their descendants, European influences are strongest in the northern parts of the continent while indigenous and African influences are relatively stronger in the south. Because of the history of colonialism, most North Americans speak English, Spanish or French, the Americas are usually accepted as having been named after the Italian explorer Amerigo Vespucci by the German cartographers Martin Waldseemüller and Matthias Ringmann. Vespucci, who explored South America between 1497 and 1502, was the first European to suggest that the Americas were not the East Indies, but a different landmass previously unknown by Europeans. In 1507, Waldseemüller produced a map, in which he placed the word America on the continent of South America. He explained the rationale for the name in the accompanying book Cosmographiae Introductio, for Waldseemüller, no one should object to the naming of the land after its discoverer. He used the Latinized version of Vespuccis name, but in its feminine form America, following the examples of Europa, Asia and Africa. Later, other mapmakers extended the name America to the continent, In 1538. Some argue that the convention is to use the surname for naming discoveries except in the case of royalty, a minutely explored belief that has been advanced is that America was named for a Spanish sailor bearing the ancient Visigothic name of Amairick. Another is that the name is rooted in a Native American language, the term North America maintains various definitions in accordance with location and context. In Canadian English, North America may be used to refer to the United States, alternatively, usage sometimes includes Greenland and Mexico, as well as offshore islands

Appalachian Plateau
–
The Appalachian Plateau is a series of rugged, high plains located on the western side of the Appalachian Highlands. The Appalachian Highlands are a range that run down the entire east coast of the United States. The Appalachian Plateau is the part of the Appalachian Mountains. The formation of the plateau began during the Paleozoic Era, regional uplift during this time caused the area to rise altogether without changing the topography of the land. The eastern side of the plateau appears as a mountain range and this false appearance is due to a very steep slope on the eastern side known as the Allegheny Front. The eastern edge is the highest part of the Appalachian Plateau, in Pennsylvania, the altitude ranges from 1,750 to 3,000 feet and continues to rise towards West Virginia, where the elevation is around 4,800 feet. From West Virginia to Tennessee the elevation lowers to 3,000 feet, on the western side of the plateau, the elevation is 900 feet in Ohio, increasing to about 2,000 feet in Kentucky. From Kentucky the elevation drops down to 500 feet in northwestern Alabama, the plateau has a slight slant towards the northwest making it higher on the eastern side. A large portion of the plateau is a coalfield that was formed approximately 320 million years ago during the Pennsylvanian Age, the plateau was subjected to glaciation during the Pleistocene ice age. As a result, the topography of this section of the plateau is flat in comparison to the rest of the province. This portion of the plateau is marked evidence of a glaciated past including bogs, lakes. The topography of the rest of the plateau was created mainly from stream erosion, the result is a rugged landscape, unlike many other plateaus, that includes many narrow stream valleys surrounded by steep ridges. A physiographic region is a portion of land that is grouped together by several factors. Each region has similar geology, topography, and groups of plants, there are eight physiographic regions in the United States. Each region is divided into provinces, there are 25 provinces in the United States, each region is then divided into sections, creating 85 different physio-graphic sections in the United States. The Appalachian Plateau is a province of the physio-graphic region Appalachian Highlands, each section is classified under the Appalachian Plateau province because of its similarities in geologic makeup, topography, and wildlife. Likewise, the Appalachian Plateau falls under the classification of Appalachian Highlands because of similar characteristics. The rock underlying the Appalachian Plateau consists of a base of Precambrian rock, on top of the basement is a thick layer, approximately 20,000 feet, of a mixture of Cambrian, Ordovician, and Middle Silurian rock

United States Geological Survey
–
The United States Geological Survey is a scientific agency of the United States government. The scientists of the USGS study the landscape of the United States, its resources. The organization has four science disciplines, concerning biology, geography, geology. The USGS is a research organization with no regulatory responsibility. The USGS is a bureau of the United States Department of the Interior, the USGS employs approximately 8,670 people and is headquartered in Reston, Virginia. The USGS also has major offices near Lakewood, Colorado, at the Denver Federal Center, the current motto of the USGS, in use since August 1997, is science for a changing world. The agencys previous slogan, adopted on the occasion of its anniversary, was Earth Science in the Public Service. Prompted by a report from the National Academy of Sciences, the USGS was created, by a last-minute amendment and it was charged with the classification of the public lands, and examination of the geological structure, mineral resources, and products of the national domain. This task was driven by the need to inventory the vast lands added to the United States by the Louisiana Purchase in 1803, the legislation also provided that the Hayden, Powell, and Wheeler surveys be discontinued as of June 30,1879. Clarence King, the first director of USGS, assembled the new organization from disparate regional survey agencies, after a short tenure, King was succeeded in the directors chair by John Wesley Powell. Administratively, it is divided into a Headquarters unit and six Regional Units, Other specific programs include, Earthquake Hazards Program monitors earthquake activity worldwide. The National Earthquake Information Center in Golden, Colorado on the campus of the Colorado School of Mines detects the location, the USGS also runs or supports several regional monitoring networks in the United States under the umbrella of the Advanced National Seismic System. The USGS informs authorities, emergency responders, the media, and it also maintains long-term archives of earthquake data for scientific and engineering research. It also conducts and supports research on long-term seismic hazards, USGS has released the UCERF California earthquake forecast. The USGS National Geomagnetism Program monitors the magnetic field at magnetic observatories and distributes magnetometer data in real time, the USGS operates the streamgaging network for the United States, with over 7400 streamgages. Real-time streamflow data are available online, since 1962, the Astrogeology Research Program has been involved in global, lunar, and planetary exploration and mapping. USGS operates a number of related programs, notably the National Streamflow Information Program. USGS Water data is available from their National Water Information System database

Coteau du Missouri
–
The terrain of the Missouri Coteau features low hummocky, undulating, rolling hills, potholes, and grasslands. Geologically the plateau is part of the plateau of the Great Plains in the Dakotas. The plateau is underlain by Pierre shale covered with hardened deposits from repeated glaciations, the plateau also contains deposits of lignite, mirabilite, and bentonite. While subjected to glaciation, it was north and west of the Driftless Area. The plateau is drained and is interspersed with glacial kettle lakes. It is transversed by several broad sags marking the ancient stream valleys of the continuations of the Grand, Moreau, Cheyenne, Bad. To the east of the plateau, the valley of the James River was formed by the lobe of the most recent ice age. Agriculturally the plateau is a grain and livestock region, Coteau des Prairies Geography of Saskatchewan Cypress Hills Interprovincial Park Cypress Hills List of highest points of Canadian provinces and territories South Dakotas Physiographic Regions

Black Hills
–
The Black Hills are a small, isolated mountain range rising from the Great Plains of North America in western South Dakota and extending into Wyoming, United States. Black Elk Peak, which rises to 7,244 feet, is the ranges highest summit, the Black Hills encompass the Black Hills National Forest. The name Black Hills is a translation of the Lakota Pahá Sápa, the hills were so-called because of their dark appearance from a distance, as they were covered in trees. Native Americans have a history in the Black Hills. After conquering the Cheyenne in 1776, the Lakota took over the territory of the Black Hills, however, when settlers discovered gold there in 1874, as a result of George Armstrong Custers Black Hills Expedition, miners swept into the area in a gold rush. As the economy of the Black Hills has shifted from natural resources since the late 20th century, locals tend to divide the Black Hills into two areas, The Southern Hills and The Northern Hills. Attractions in the Northern Hills include Spearfish Canyon, historic Deadwood, the first Rally was held on August 14,1938 and the 75th Rally in 2015 saw more than 1 million bikers visit the Black Hills. Devils Tower National Monument, located in the Wyoming Black Hills, is an important nearby attraction and was the United States first national monument. Scientists have been able to utilize carbon-dating to evaluate the age of tools found in the area, stratigraphic records indicate environmental changes in the land, such as flood and drought patterns. For example, large-scale flooding of the Black Hill basins occurs at a probability rate of 0.01, however, during The Medieval Climate Anomaly, or the Medieval Warm Period, flooding increased in the basins. The Arikara arrived by AD1500, followed by the Cheyenne, Crow, Kiowa, the Lakota arrived from Minnesota in the 18th century and drove out the other tribes, who moved west. They claimed the land, which they called Ȟe Sápa, the mountains commonly became known as the Black Hills. François and Louis de La Vérendrye probably travelled near the Black Hills in 1743, fur trappers and traders had some dealings with the Native Americans. European Americans increasingly encroached on Lakota territory, in this treaty, they protected the Black Hills forever from European-American settlement. Both the Sioux and Cheyenne also claimed rights to the land, saying that in their cultures, it was considered the axis mundi, an official announcement of gold was made by the newspaper reporters accompanying the expedition. The following year, the Newton-Jenney Party conducted the first detailed survey of the Black Hills, the surveyor for the party, Dr. Valentine McGillycuddy, was the first European American to ascend to the top of Black Elk Peak. This highest point in the Black Hills is 7,242 feet above sea level, during the 1875–1878 gold rush, thousands of miners went to the Black Hills, in 1880, the area was the most densely populated part of the Dakota Territory. Three large towns developed in the Northern Hills, Deadwood, Central City, around these were groups of smaller gold camps, towns, and villages
