Ansel Adams
–
Ansel Easton Adams was an American photographer and environmentalist. His black and white photographs of the American West, especially Yosemite National Park, have been widely reproduced on calendars, posters, books. Adams and Fred Archer developed the Zone System as a way to determine proper exposure, the resulting clarity and depth characterized his photographs. He primarily used large-format cameras because their high resolution helped ensure sharpness in his images, Adams founded the photography group known as Group f/64, along with fellow photographers Willard Van Dyke and Edward Weston. Adams was born in the Western Addition of San Francisco, California and he was named after his uncle, Ansel Easton. His mothers family came from Baltimore, where his grandfather had a successful freight-hauling business but lost his wealth investing in failed mining. The Adams family came from New England, having migrated from Northern Ireland in the early 18th century and his paternal grandfather founded and built a prosperous lumber business which his father later ran, though his fathers natural talents lay more with sciences than with business. Later in life, Adams condemned that very same industry for cutting many of the great redwood forests. In 1907, his family moved 2 miles west to a new home near the Seacliff neighbourhood, the home had a splendid view of the Golden Gate and the Marin Headlands. San Francisco was devastated by the April 18,1906 San Francisco earthquake, the four year-old Ansel Adams was uninjured in the initial shaking but was tossed face-first into a garden wall during an aftershock three hours later, breaking and scarring his nose. Among his earliest memories was watching the smoke from the fire that destroyed much of the city a few miles to the east. A doctor recommended that his nose be reset once he reached maturity, Adams was a hyperactive child and prone to frequent sickness and hypochondria. He had few friends, but his home and surroundings on the heights facing the Golden Gate provided ample childhood activities. His father bought a telescope, and they enthusiastically shared the hobby of amateur astronomy. His father went on to serve as the paid secretary-treasurer of the Astronomical Society of the Pacific from 1925 to 1950, Ansels fathers business suffered great financial losses after the death of Ansels grandfather and the aftermath of the Panic of 1907. By 1912, the standard of living had dropped sharply. Ansel was dismissed from several schools for being restless and inattentive. Adams was then educated by tutors, his aunt Mary

Summit
–
A summit is a point on a surface that is higher in elevation than all points immediately adjacent to it. Mathematically, a summit is a maximum in elevation. The topographic terms acme, apex, peak, and zenith are synonymous, the UIAA definition is that a summit is independent if it has a prominence of 30 metres or more, it is a mountain if it has a prominence of at least 300 metres. This can be summarised as follows, A pyramidal peak is an exaggerated form produced by ice erosion of a mountain top, Summit may also refer to the highest point along a line, trail, or route. In many parts of the western United States, the term refers to the highest point along a road, highway. For example, the highest point along Interstate 80 in California is referred to as Donner Summit while the highest point on Interstate 5 is Siskiyou Mountain Summit, geoid Hill List of highest mountains Maxima and minima Nadir Summit accordance Peak finder

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

Wyoming
–
Wyoming /waɪˈoʊmɪŋ/ is a state in the mountain region of the western United States. The state is the tenth largest by area, the least populous, 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. Cheyenne is the capital and the most populous city in Wyoming, the state population was estimated at 586,107 in 2015, which is less than the population of 31 of the largest U. S. cities. The Crow, Arapaho, Lakota, and Shoshone were some of the inhabitants of the region. 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. The Great Plains meet the Rocky Mountains in Wyoming, the state is a great plateau broken by many mountain ranges. Surface elevations range from the summit of Gannett Peak in the Wind River Mountain Range, at 13,804 feet, to the Belle Fourche River valley in the states northeast corner, at 3,125 feet. In the northwest are the Absaroka, Owl Creek, Gros Ventre, Wind River, in the north central are the Big Horn Mountains, in the northeast, the Black Hills, and in the southern region the Laramie, Snowy and Sierra Madre ranges. The Snowy Range in the central part of the state is an extension of the Colorado Rockies in both geology and appearance. The Wind River Range in the west central part of the state is remote and includes more than 40 mountain peaks in excess of 13,000 ft tall in addition to Gannett Peak, the highest peak in the state. The Big Horn Mountains in the central portion are somewhat isolated from the bulk of the Rocky Mountains

Mountain range
–
A mountain range is a geographic area containing numerous geologically related mountains. A mountain system or system of ranges, sometimes is used to combine several geological features that are geographically related. Mountain ranges are usually segmented by highlands or mountain passes and valleys, individual mountains within the same mountain range do not necessarily have the same geologic structure or petrology. They may be a mix of different orogenic expressions and terranes, for example thrust sheets, uplifted blocks, fold mountains, most geologically young mountain ranges on the Earths land surface are associated with either the Pacific Ring of Fire or the Alpide Belt. The Andes is 7,000 kilometres long and is considered the worlds longest mountain system. The Alpide belt includes Indonesia and southeast Asia, through the Himalaya, the belt also includes other European and Asian mountain ranges. The Himalayas contain the highest mountains in the world, including Mount Everest, mountain ranges outside of these two systems include the Arctic Cordillera, the Urals, the Appalachians, the Scandinavian Mountains, the Altai Mountains and the Hijaz Mountains. If the definition of a range is stretched to include underwater mountains. The mountain systems of the earth are characterized by a tree structure, the sub-range relationship is often expressed as a parent-child relationship. For example, the White Mountains of New Hampshire and the Blue Ridge Mountains are sub-ranges of the Appalachian Mountains, equivalently, the Appalachians are the parent of the White Mountains and Blue Ridge Mountains, and the White Mountains and the Blue Ridge Mountains are children of the Appalachians. The position of mountains influences climate, such as rain or snow, when air masses move up and over mountains, the air cools producing orographic precipitation. As the air descends on the side, it warms again and is drier. Often, a shadow will affect the leeward side of a range. Mountain ranges are constantly subjected to forces which work to tear them down. Erosion is at work while the mountains are being uplifted and long after until the mountains are reduced to low hills, rivers are traditionally believed to be the principle erosive factor on mountain ranges, with their ability of bedrock incision and sediment transport. The rugged topography of a range is the product of erosion. The basins adjacent to a mountain range are filled with sediments which are buried and turned into sedimentary rock. The early Cenozoic uplift of the Rocky Mountains of Colorado provides an example and this mass of rock was removed as the range was actively undergoing uplift

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

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

Idaho
–
Idaho is a state in the northwestern region of the United States. It borders the state of Montana to the east and northeast, Wyoming to the east, Nevada and Utah to the south, to the north, it shares a small portion of the Canadian border with the province of British Columbia. With a population of around 1.7 million people and an area of 83,569 square miles, Idaho is the 14th largest, the states capital and largest city is Boise. Idaho prior to European settlement was inhabited solely by Native American peoples, in the early 19th century, Idaho was considered part of the Oregon Country, an area disputed between the U. S. and the United Kingdom. Idaho was eventually admitted to the Union on July 3,1890, forming part of the Pacific Northwest, Idaho is divided into several distinct geographic and climatic regions. In the states north, the relatively isolated Idaho Panhandle is closely linked with Eastern Washington, the states south includes the Snake River Plain, while the south-east incorporates part of the Great Basin. Idaho is quite mountainous, and contains several stretches of the Rocky Mountains, additionally, around 38 percent of Idahos land is held by the United States Forest Service, the most of any state. Industries significant for the economy include manufacturing, agriculture, mining, forestry. Idahos agricultural sector supplies a number of different products, but the state is best known for its potato crop, the official state nickname is the Gem State, which references Idahos reputation for gemstones and, more broadly, its many wilderness areas. The exact origin of the remains a mystery. Willing later claimed that he had invented the name. Congress ultimately decided to name the area Colorado Territory when it was created in February 1861, thinking they would get a jump on the name, locals named a community in Colorado Idaho Springs. However, the name Idaho did not fall into obscurity, the same year Congress created Colorado Territory, a county called Idaho County was created in eastern Washington Territory. The county was named after a steamship named Idaho, which was launched on the Columbia River in 1860 and it is unclear whether the steamship was named before or after Willings claim was revealed. Regardless, a portion of Washington Territory, including Idaho County, was used to create Idaho Territory in 1863. Despite this lack of evidence for the origin of the name, the name Idaho may be derived from the Plains Apache word ídaahę́, which means enemy. The Comanches used this word to refer to the Idaho Territory, a 1956 Idaho history textbook says, Idaho is a Shoshoni Indian exclamation. The word consists of three parts, the first is Ee, which in English conveys the idea of coming down

Yellowstone National Park
–
Yellowstone National Park is a national park located in the U. S. states of Wyoming, Montana and Idaho. It was established by the U. S. Congress and signed into law by President Ulysses S. Grant on March 1,1872. Yellowstone was the first National Park in the U. S. and is widely held to be the first national park in the world. The park is known for its wildlife and its many features, especially Old Faithful Geyser. It has many types of ecosystems, but the subalpine forest is the most abundant and it is part of the South Central Rockies forests ecoregion. Native Americans have lived in the Yellowstone region for at least 11,000 years, aside from visits by mountain men during the early-to-mid-19th century, organized exploration did not begin until the late 1860s. Management and control of the park fell under the jurisdiction of the Secretary of the Interior. However, the U. S. Army was subsequently commissioned to oversee management of Yellowstone for a 30-year period between 1886 and 1916, in 1917, administration of the park was transferred to the National Park Service, which had been created the previous year. Hundreds of structures have been built and are protected for their architectural and historical significance, Yellowstone National Park spans an area of 3,468.4 square miles, comprising lakes, canyons, rivers and mountain ranges. Yellowstone Lake is one of the largest high-elevation lakes in North America and is centered over the Yellowstone Caldera, the caldera is considered an active volcano. It has erupted with tremendous force several times in the last two million years, half of the worlds geothermal features are in Yellowstone, fueled by this ongoing volcanism. Lava flows and rocks from volcanic eruptions cover most of the area of Yellowstone. The park is the centerpiece of the Greater Yellowstone Ecosystem, the largest remaining nearly-intact ecosystem in the Earths northern temperate zone, hundreds of species of mammals, birds, fish, and reptiles have been documented, including several that are either endangered or threatened. The vast forests and grasslands also include species of plants. Yellowstone Park is the largest and most famous location in the Continental United States. Grizzly bears, wolves, and free-ranging herds of bison and elk live in the park, the Yellowstone Park bison herd is the oldest and largest public bison herd in the United States. Forest fires occur in the each year, in the large forest fires of 1988. Yellowstone has numerous opportunities, including hiking, camping, boating, fishing and sightseeing

Voyageurs
–
The voyageurs were French Canadians who engaged in the transporting of furs by canoe during the fur trade years. Voyageur is a French word, meaning traveler, the emblematic meaning of the term applies to places and times where transportation of materials was mainly over long distances. This major and challenging task of the fur trading business was done by canoe, the term in its fur trade context also applied, at a lesser extent, to other fur trading activities. Being a voyageur also included being a part of a licensed, organized effort, additionally, they were set apart from engagés, who were much smaller merchants and general laborers. Mostly immigrants, engagés were men who were obliged to go anywhere, until their contract expired, engagés were at the full servitude of their master, which was most often a voyageur. Less than fifty percent of engagés whose contracts ended chose to remain in New France, the voyageurs were regarded as legendary, especially in French Canada. They were heroes celebrated in folklore and music, for reasons of promised celebrity status and wealth, this position was very coveted. James H. Baker was once told by an unnamed retired voyageur, I could carry, paddle, walk, I have been twenty-four years a canoe man, and forty-one years in service, no portage was ever too long for me, fifty songs could I sing. I have saved the lives of ten voyageurs, have had twelve wives, I spent all of my money in pleasure. Were I young again, I would spend my life the way over. There is no life so happy as a voyageurs life, despite the fame surrounding the voyageur, their life was one of toil and not nearly as glorious as folk tales make it out to be. For example, they had to be able to carry two 90-pound bundles of fur over portage, some carried up to four or five, and there is a report of a voyageur carrying seven for half of a mile. Hernias were common and frequently caused death, most voyageurs would start working when they were twenty two and they would continue working until they were in their sixties. They never made enough money to consider an early retirement from what was a physically grueling lifestyle, Europeans mainly traded alongside the coast of North America with Native Americans. The early fur trade with Native Americans, which developed alongside the coasts of North America, was not limited to the beaver, beavers were not particularly valued and people preferred fancy fur or fur that is used with or on the pelt. The fur trade was viewed as secondary to fishing during this era, soon, coureurs des bois achieved business advantages by travelling deeper into the wilderness and trading there. By 1681, the King of France decided to control the traders by publishing an edict that banned fur, also, as the trading process moved deeper into the wilderness, transportation of the furs became a larger part of the fur trading business process. The authorities began a process of issuing permits and those travellers associated with the canoe transportation part of the licensed endeavour became known as voyageurs, a term which literally means traveler in French
