Taxonomy (biology)
–
Taxonomy is the science of defining groups of biological organisms on the basis of shared characteristics and giving names to those groups. The exact definition of taxonomy varies from source to source, but the core of the remains, the conception, naming. There is some disagreement as to whether biological nomenclature is considered a part of taxonomy, the broadest meaning of taxonomy is used here. The word taxonomy was introduced in 1813 by Candolle, in his Théorie élémentaire de la botanique, the term alpha taxonomy is primarily used today to refer to the discipline of finding, describing, and naming taxa, particularly species. In earlier literature, the term had a different meaning, referring to morphological taxonomy, ideals can, it may be said, never be completely realized. They have, however, a value of acting as permanent stimulants. Some of us please ourselves by thinking we are now groping in a beta taxonomy, turrill thus explicitly excludes from alpha taxonomy various areas of study that he includes within taxonomy as a whole, such as ecology, physiology, genetics, and cytology. He further excludes phylogenetic reconstruction from alpha taxonomy, thus, Ernst Mayr in 1968 defined beta taxonomy as the classification of ranks higher than species. This activity is what the term denotes, it is also referred to as beta taxonomy. How species should be defined in a group of organisms gives rise to practical and theoretical problems that are referred to as the species problem. The scientific work of deciding how to define species has been called microtaxonomy, by extension, macrotaxonomy is the study of groups at higher taxonomic ranks, from subgenus and above only, than species. While some descriptions of taxonomic history attempt to date taxonomy to ancient civilizations, earlier works were primarily descriptive, and focused on plants that were useful in agriculture or medicine. There are a number of stages in scientific thinking. Early taxonomy was based on criteria, the so-called artificial systems. Later came systems based on a complete consideration of the characteristics of taxa, referred to as natural systems, such as those of de Jussieu, de Candolle and Bentham. The publication of Charles Darwins Origin of Species led to new ways of thinking about classification based on evolutionary relationships and this was the concept of phyletic systems, from 1883 onwards. This approach was typified by those of Eichler and Engler, the advent of molecular genetics and statistical methodology allowed the creation of the modern era of phylogenetic systems based on cladistics, rather than morphology alone. Taxonomy has been called the worlds oldest profession, and naming and classifying our surroundings has likely been taking place as long as mankind has been able to communicate

Plant
–
Plants are mainly multicellular, predominantly photosynthetic eukaryotes of the kingdom Plantae. The term is generally limited to the green plants, which form an unranked clade Viridiplantae. This includes the plants, conifers and other gymnosperms, ferns, clubmosses, hornworts, liverworts, mosses and the green algae. Green plants have cell walls containing cellulose and obtain most of their energy from sunlight via photosynthesis by primary chloroplasts and their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic and have lost the ability to produce amounts of chlorophyll or to photosynthesize. Plants are characterized by sexual reproduction and alternation of generations, although reproduction is also common. There are about 300–315 thousand species of plants, of which the great majority, green plants provide most of the worlds molecular oxygen and are the basis of most of Earths ecologies, especially on land. Plants that produce grains, fruits and vegetables form humankinds basic foodstuffs, Plants play many roles in culture. They are used as ornaments and, until recently and in variety, they have served as the source of most medicines. The scientific study of plants is known as botany, a branch of biology, Plants are one of the two groups into which all living things were traditionally divided, the other is animals. The division goes back at least as far as Aristotle, who distinguished between plants, which generally do not move, and animals, which often are mobile to catch their food. Much later, when Linnaeus created the basis of the system of scientific classification. Since then, it has become clear that the plant kingdom as originally defined included several unrelated groups, however, these organisms are still often considered plants, particularly in popular contexts. When the name Plantae or plant is applied to a group of organisms or taxon. The evolutionary history of plants is not yet settled. Those which have been called plants are in bold, the way in which the groups of green algae are combined and named varies considerably between authors. Algae comprise several different groups of organisms which produce energy through photosynthesis, most conspicuous among the algae are the seaweeds, multicellular algae that may roughly resemble land plants, but are classified among the brown, red and green algae. Each of these groups also includes various microscopic and single-celled organisms

Pinophyta
–
The Pinophyta, also known as Coniferophyta or Coniferae, or commonly as conifers, are a division of vascular land plants containing a single class, Pinopsida. They are gymnosperms, cone-bearing seed plants, all extant conifers are perennial woody plants with secondary growth. The great majority are trees, though a few are shrubs, examples include cedars, Douglas firs, cypresses, firs, junipers, kauri, larches, pines, hemlocks, redwoods, spruces, and yews. As of 1998, the division Pinophyta was estimated to contain eight families,68 genera, although the total number of species is relatively small, conifers are ecologically important. They are the dominant plants over large areas of land, most notably the taiga of the Northern Hemisphere, boreal conifers have many wintertime adaptations. The narrow conical shape of northern conifers, and their downward-drooping limbs, many of them seasonally alter their biochemistry to make them more resistant to freezing. While tropical rainforests have more biodiversity and turnover, the conifer forests of the world represent the largest terrestrial carbon sink. Conifers are of economic value for softwood lumber and paper production. The earliest conifers in the record date to the late Carboniferous period, possibly arising from Cordaites. Pinophytes, Cycadophytes, and Ginkgophytes all developed at this time, an important adaptation of these gymnosperms was allowing plants to live without being so dependent on water. Other adaptations are pollen and the seed, which allows the embryo to be transported and developed elsewhere, Conifers appear to be one of the taxa that benefited from the Permian–Triassic extinction event, and were the dominant land plants of the Mesozoic. They were overtaken by the plants, which first appeared in the Cretaceous. They were the food of herbivorous dinosaurs, and their resins and poisons would have given protection against herbivores. Reproductive features of modern conifers had evolved by the end of the Mesozoic era, Conifer is a Latin word, a compound of conus and ferre, meaning the one that bears cone. A descriptive name in use for the conifers is Coniferae. Alternatively, descriptive botanical names may also be used at any rank above family and this means that if conifers are considered a division, they may be called Pinophyta or Coniferae. As a class they may be called Pinopsida or Coniferae, as an order they may be called Pinales or Coniferae or Coniferales. Conifers are the largest and economically most important component group of the gymnosperms, the division Pinophyta consists of just one class, Pinopsida, which includes both living and fossil taxa
4.
Larch
–
Larches are conifers in the genus Larix, in the family Pinaceae. Growing from 20 to 45 m tall, they are native to much of the temperate northern hemisphere, on lowlands in the north. Larches are among the dominant plants in the forests of Siberia. Although they are conifers, larches are deciduous trees lose their needles in the autumn. The leaves are needle-like, 2–5 centimetres long, slender, larches are among the few deciduous conifers, which are mostly evergreen. There are eleven accepted species of larch, Larix czekanowskii Szafer Larix decidua Mill, plains of central and eastern Siberia. Mountains of eastern Himalaya Larix kaempferi Carr, Larix laricina K. Koch Tamarack larch or American larch. Parts of Alaska and throughout Canada and the northern United States from the eastern Rocky Mountains to the Atlantic shore, Mountains of northwest United States and southwest Canada, at very high altitude. Larix mastersiana Rehder & E. H. Wilson Masters larch, Mountains of northwest United States and southwest Canada, at lower altitudes. Most if not all of the species can be hybridised in cultivation, currently-accepted hybrids are, Larix × lubarskii Sukaczev Larix × maritima Sukaczev Larix × polonica Racib. Larch is used as a plant by the larvae of a number of Lepidoptera species—see list of Lepidoptera that feed on larches. In Canada, this disease was first detected in 1980 and is harmful to an indigenous species larch. Larches are also vulnerable to Phytophthora ramorum, in late 2009 the disease was first found in Japanese larch trees in the English counties of Devon, Cornwall and Somerset, and has since spread to the south-west of Scotland. In August 2010 the disease was found in Japanese larch trees in counties Waterford and Tipperary in Ireland, larch wood is valued for its tough, waterproof and durable qualities. Top quality knot-free timber is in demand for building yachts and other small boats, for exterior cladding of buildings. The timber is resistant to rot when in contact with the ground, the hybrid Dunkeld larch is widely grown as a timber crop in Northern Europe, valued for its fast growth and disease resistance. Larch has also used in herbal medicine, see Bach flower remedies. In Central Europe larch is viewed as one of the best wood materials for the building of residences, planted on borders with birch, both tree species were used in pagan cremations

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

Yukon
–
Yukon is the smallest and westernmost of Canadas three federal territories. The territory has the smallest population of any province or territory in Canada, Whitehorse is the territorial capital and Yukons only city. The territory was split from the Northwest Territories in 1898 and was named the Yukon Territory, though officially bilingual, the Yukon Government also recognizes First Nations languages. At 5,959 m, Yukons Mount Logan, in Kluane National Park and Reserve, is the highest mountain in Canada, most of Yukon has a subarctic climate, characterized by long cold winters and brief warm summers. The Arctic Ocean coast has a tundra climate, notable rivers include the Yukon River, after which the territory was named, as well as the Pelly, Stewart, Peel, White and Tatshenshini rivers. Long before the arrival of Europeans, central and southern Yukon was populated by First Nations people, sites of archeological significance in Yukon hold some of the earliest evidence of the presence of human occupation in North America. The sites safeguard the history of the first people and the earliest First Nations of the Yukon, the volcanic eruption of Mount Churchill in approximately 800 AD in what is now the U. S. Coastal and inland First Nations had extensive trading networks, European incursions into the area only began early in the 19th century with the fur trade, followed by missionaries. By the 1870s and 1880s gold miners began to arrive and this drove a population increase that justified the establishment of a police force, just in time for the start of the Klondike Gold Rush in 1897. The increased population coming with the gold led to the separation of the Yukon district from the Northwest Territories. Its northern coast is on the Beaufort Sea and its ragged eastern boundary mostly follows the divide between the Yukon Basin and the Mackenzie River drainage basin to the east in the Mackenzie mountains. Most of the territory is in the watershed of its namesake, the southern Yukon is dotted with a large number of large, long and narrow glacier-fed alpine lakes, most of which flow into the Yukon River system. The larger lakes include Teslin Lake, Atlin Lake, Tagish Lake, Marsh Lake, Lake Laberge, Kusawa Lake, bennett Lake on the Klondike Gold Rush trail is a lake flowing into Nares Lake, with the greater part of its area within Yukon. Canadas highest point, Mount Logan, is in the territorys southwest, Mount Logan and a large part of the Yukons southwest are in Kluane National Park and Reserve, a UNESCO World Heritage Site. Other national parks include Ivvavik National Park and Vuntut National Park in the north, other watersheds include the Mackenzie River, the Peel Watershed and the Alsek–Tatshenshini, and a number of rivers flowing directly into the Beaufort Sea. The two main Yukon rivers flowing into the Mackenzie in the Northwest Territories are the Liard River in the southeast, notable widespread tree species within Yukon are the black spruce and white spruce. Many trees are stunted because of the growing season and severe climate. The capital, Whitehorse, is also the largest city, with about three-quarters of the population, the second largest is Dawson City, which was the capital until 1952

Inuvik
–
Inuvik /ᵻˈnuːvɪk/ is a town in the Northwest Territories of Canada and is the administrative centre for the Inuvik Region. The population as of the 2011 Census was 3,484, the two previous census counts show wide fluctuations due to economic conditions,2,894 in 2001 and 3,296 in 1996. In 2012 the Government of the Northwest Territories reported that the population was 3,321 with a yearly growth rate of 0. 2% from 2001. Inuvik was conceived in 1953 as a replacement administrative centre for the hamlet of Aklavik on the west of the Mackenzie Delta, initially called New Aklavik, it was renamed Inuvik in 1958. The school was built in 1959 and the hospital, government offices and staff residences in 1960, naval Radio Station Inuvik, callsign CFV, was commissioned on 10 September 1963 after operations had been successfully transferred from NRS Aklavik. Station CFV was part of the SUPRAD network of intercept and direction finding stations, CFS Inuvik closed on 1 April 1986 and the site was transferred to the Dept. of Transport for use as a telecommunications station. Nothing remains of CFS Inuvik today, even now, many people of all backgrounds still lament its closing. The Navy Operations base at the end of Navy Road was completely dismantled and removed, Inuvik achieved village status in 1967 and became a full town in 1979 with an elected mayor and council. This all collapsed in 1990 for a variety of reasons, including disappearing government subsidies, local resistance to petroleum exploration, on 10 February 2010, the Google Street View imaging service uploaded images of most Inuvik streets. Local CBC Radio broadcasts an hour of programming a day in each of these languages, there are also about 100 Muslims, most of whom came there for economic opportunities. A small mosque was established in 2010, Inuvik is located on the East Channel of the Mackenzie Delta, approximately 100 km from the Arctic Ocean and approximately 200 km north of the Arctic Circle. Due to its location, Inuvik experiences an average of 56 days of continuous sunlight every summer and 30 days of polar night every winter. Access is via the Dempster Highway for the majority of the year, the highway relies on ferries and ice bridges to get across the rivers. It is thus closed during the time of freeze-up, for ice to form and allow ice bridges, at these times, there is air access only. The main airport is Inuvik Airport and there is a general aviation airport, when the Mackenzie River is ice-free, Northern Transportation Company Limited provides a commercial barge service from Hay River, on Great Slave Lake to the regional terminal in Inuvik. The annual sealift moves supplies as far east as Taloyoak, Nunavut and west to Barrow, a distinct feature of Inuvik is the use of utilidors – above-ground utility conduits carrying water and sewage – which are covered by corrugated steel. They run throughout town connecting most buildings, and as a result there are small bridges and underpasses. The utilidors are necessary because of the permafrost underlying the town, another feature is an inukhuk placed outside the Mackenzie Hotel, which was rebuilt in 2006

Northwest Territories
–
The Northwest Territories is a territory of Canada. At a land area of approximately 1,144,000 km2 and its estimated population as of 2016 is 44,291. Yellowknife became the capital in 1967, following recommendations by the Carrothers Commission. The Northwest Territories are bordered by Canadas two other territories, Nunavut to the east and Yukon to the west, and by the provinces of British Columbia, Alberta, and Saskatchewan to the south. The name is descriptive, adopted by the British government during the era to indicate where it lay in relation to Ruperts Land. It is shortened from North-Western Territory, in Inuktitut, the Northwest Territories are referred to as ᓄᓇᑦᓯᐊᖅ, beautiful land. There was some discussion of changing the name of the Northwest Territories after the splitting off of Nunavut, one proposal was Denendeh, as advocated by the former premier Stephen Kakfwi, among others. One of the most popular proposals for a new name – one to name the territory Bob – began as a prank, in the end a poll conducted prior to division showed that strong support remained to keep the name Northwest Territories. This name arguably became more appropriate following division than it had been when the territories extended far into Canadas north-central and it possibly meets Manitoba at a quadripoint to the extreme southeast, though surveys have not been completed. It has an area of 1,183,085 km2. Territorial islands in the Canadian Arctic Archipelago include Banks Island, Borden Island, Prince Patrick Island and its highest point is Mount Nirvana near the border with Yukon at an elevation of 2,773 m. The Northwest Territories extends for more than 1,300,000 km2 and has a large climate variant from south to north, the southern part of the territory has a subarctic climate, while the islands and northern coast have a polar climate. Summers in the north are short and cool, with highs in the mid teens Celsius. Winters are long and harsh, daytime highs in the mid −20 °C, extremes are common with summer highs in the south reaching 36 °C and lows reaching into the negatives. In winter in the south, it is not uncommon for the temperatures to reach −40 °C, in the north, temperatures can reach highs of 30 °C, and lows can reach into the low negatives. In winter in the north it is not uncommon for the temperatures to reach −50 °C, thunderstorms are not rare in the south. In the north they are rare, but do occur. Tornadoes are extremely rare but have happened with the most notable one happening just outside Yellowknife that destroyed a communications tower, the Territory has a fairly dry climate due to the mountains in the west

Newfoundland (island)
–
Newfoundland is a large Canadian island off the east coast of the North American mainland, and the most populous part of the Canadian province of Newfoundland and Labrador. It has 29 percent of the land area. The island is separated from the Labrador Peninsula by the Strait of Belle Isle and it blocks the mouth of the Saint Lawrence River, creating the Gulf of Saint Lawrence, the worlds largest estuary. Newfoundlands nearest neighbour is the French overseas community of Saint-Pierre and Miquelon, with an area of 108,860 square kilometres, Newfoundland is the worlds 16th-largest island, Canadas fourth-largest island, and the largest Canadian island outside the North. The provincial capital, St. Johns, is located on the southeastern coast of the island, Cape Spear, just south of the capital, is the easternmost point of North America, excluding Greenland. It is common to consider all directly neighbouring islands such as New World, Twillingate, Fogo, by that classification, Newfoundland and its associated small islands have a total area of 111,390 square kilometres. Additionally 6. 1% claimed at least one parent of French ancestry, the islands total population as of the 2006 census was 479,105. Long settled by peoples of the Dorset culture, the island was visited by the Icelandic Viking Leif Eriksson in the 11th century. The next European visitors to Newfoundland were Portuguese, Basque, Spanish, French, the island was visited by the Genoese navigator John Cabot, working under contract to King Henry VII of England on his expedition from Bristol in 1497. In 1501, Portuguese explorers Gaspar Corte-Real and his brother Miguel Corte-Real charted part of the coast of Newfoundland in a attempt to find the Northwest Passage. Newfoundland is considered Britains oldest colony, at the time of English settlement, the Beothuk inhabited the island. While there is evidence of ancient indigenous peoples on the island. LAnse aux Meadows was a Norse settlement near the northernmost tip of Newfoundland, the site is considered the only undisputed evidence of Pre-Columbian contact between the Old and New Worlds, if the Norse-Inuit contact on Greenland is not counted. There is a second suspected Norse site in Point Rosee, the island is a likely location of Vinland, mentioned in the Viking Chronicles, although this has been disputed. The indigenous people on the island at the time of European settlement were the Beothuk, later immigrants developed a variety of dialects associated with settlement on the island, Newfoundland English, Newfoundland French. In the 19th century, it also had a dialect of Irish known as Newfoundland Irish, Scottish Gaelic was spoken on the island during the 19th and early 20th centuries, particularly in the Codroy Valley area, chiefly by settlers from Cape Breton Island, Nova Scotia. The Gaelic names reflected the association with fishing, in Scottish Gaelic, it was called Eilean a Trosg, or literally, similarly, the Irish Gaelic name Talamh an Éisc means Land of the Fish. The first inhabitants of Newfoundland were the Paleo-Eskimo, who have no link to other groups in Newfoundland history

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

Minnesota
–
Minnesota is a state in the midwestern and northern regions of the United States. Minnesota was admitted as the 32nd U. S. state on May 11,1858, the state has a large number of lakes, and is known by the slogan Land of 10,000 Lakes. Its official motto is LÉtoile du Nord, Minnesota is the 12th largest in area and the 21st most populous of the U. S. Minnesota is known for its progressive political orientation and its high rate of civic participation and voter turnout. Until European settlement, Minnesota was inhabited by the Dakota and Ojibwe/Anishinaabe, in recent decades, immigration from Asia, the Horn of Africa, and Latin America has broadened its historic demographic and cultural composition. Minnesotas standard of living index is among the highest in the United States, Native Americans demonstrated the name to early settlers by dropping milk into water and calling it mnisota. Many places in the state have similar names, such as Minnehaha Falls, Minneiska, Minneota, Minnetonka, Minnetrista, and Minneapolis, a combination of mni and polis, Minnesota is the second northernmost U. S. state. Its isolated Northwest Angle in Lake of the Woods county is the part of the 48 contiguous states lying north of the 49th parallel. The state is part of the U. S. region known as the Upper Midwest and it shares a Lake Superior water border with Michigan and a land and water border with Wisconsin to the east. Iowa is to the south, North Dakota and South Dakota are to the west, with 86,943 square miles, or approximately 2.25 percent of the United States, Minnesota is the 12th-largest state. Minnesota has some of the Earths oldest rocks, gneisses that are about 3.6 billion years old. About 2.7 billion years ago, basaltic lava poured out of cracks in the floor of the primordial ocean, the roots of these volcanic mountains and the action of Precambrian seas formed the Iron Range of northern Minnesota. Following a period of volcanism 1, in more recent times, massive ice sheets at least one kilometer thick ravaged the landscape of the state and sculpted its terrain. The Wisconsin glaciation left 12,000 years ago and these glaciers covered all of Minnesota except the far southeast, an area characterized by steep hills and streams that cut into the bedrock. This area is known as the Driftless Zone for its absence of glacial drift, much of the remainder of the state outside the northeast has 50 feet or more of glacial till left behind as the last glaciers retreated. Gigantic Lake Agassiz formed in the northwest 13,000 years ago and its bed created the fertile Red River valley, and its outflow, glacial River Warren, carved the valley of the Minnesota River and the Upper Mississippi downstream from Fort Snelling. Minnesota is geologically quiet today, it experiences earthquakes infrequently, the states high point is Eagle Mountain at 2,301 feet, which is only 13 miles away from the low of 601 feet at the shore of Lake Superior. Notwithstanding dramatic local differences in elevation, much of the state is a rolling peneplain. Two major drainage divides meet in Minnesotas northeast in rural Hibbing, forming a triple watershed, precipitation can follow the Mississippi River south to the Gulf of Mexico, the Saint Lawrence Seaway east to the Atlantic Ocean, or the Hudson Bay watershed to the Arctic Ocean

Maryland
–
The states largest city is Baltimore, and its capital is Annapolis. Among its occasional nicknames are Old Line State, the Free State, the state is named after Henrietta Maria of France, the wife of Charles I of England. George Calvert was the first Lord of Baltimore and the first English proprietor of the colonial grant. Maryland was the state to ratify the United States Constitution. Maryland is one of the smallest U. S. states in terms of area, as well as one of the most densely populated, Maryland has an area of 12,406.68 square miles and is comparable in overall area with Belgium. It is the 42nd largest and 9th smallest state and is closest in size to the state of Hawaii, the next largest state, its neighbor West Virginia, is almost twice the size of Maryland. Maryland possesses a variety of topography within its borders, contributing to its nickname America in Miniature. The mid-portion of this border is interrupted by Washington, D. C. which sits on land that was part of Montgomery and Prince Georges counties and including the town of Georgetown. This land was ceded to the United States Federal Government in 1790 to form the District of Columbia, the Chesapeake Bay nearly bisects the state and the counties east of the bay are known collectively as the Eastern Shore. Close to the town of Hancock, in western Maryland, about two-thirds of the way across the state. This geographical curiosity makes Maryland the narrowest state, bordered by the Mason–Dixon line to the north, portions of Maryland are included in various official and unofficial geographic regions. Much of the Baltimore–Washington corridor lies just south of the Piedmont in the Coastal Plain, earthquakes in Maryland are infrequent and small due to the states distance from seismic/earthquake zones. The M5.8 Virginia earthquake in 2011 was felt moderately throughout Maryland, buildings in the state are not well-designed for earthquakes and can suffer damage easily. The lack of any glacial history accounts for the scarcity of Marylands natural lakes, laurel Oxbow Lake is an over one-hundred-year-old 55-acre natural lake two miles north of Maryland City and adjacent to Russett. Chews Lake is a natural lake two miles south-southeast of Upper Marlboro. There are numerous lakes, the largest of them being the Deep Creek Lake. Maryland has shale formations containing natural gas, where fracking is theoretically possible, as is typical of states on the East Coast, Marylands plant life is abundant and healthy. Middle Atlantic coastal forests, typical of the southeastern Atlantic coastal plain, grow around Chesapeake Bay, moving west, a mixture of Northeastern coastal forests and Southeastern mixed forests cover the central part of the state
