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

Grand Teton
–
Grand Teton is the highest mountain in Grand Teton National Park, in Northwest Wyoming, and a classic destination in American mountaineering. Grand Teton, at 13,775 feet, is the highest point of the Teton Range, the mountain is entirely within the Snake River drainage basin, which it feeds by several local creeks and glaciers. The Teton Range is a subrange of the Rocky Mountains, which extend from southern Alaska to northern New Mexico, Grand Tetons name was first recorded as Mount Hayden by the Washburn-Langford-Doane Expedition of 1870. However, the name the Grand Teton had early currency, the Edition of April,1901 of the USGS1,125,000 quadrangle map of the area shows Grand Teton as the name of the peak. A United States National Park named Grand Teton National Park was established by law in 1929, by 1931, the name Grand Teton Peak was in such common usage that it was recognized by the USGS Board on Geographic Names. Another shift in usage led the Board to shorten the name on maps to Grand Teton in 1970, the origin of the name is disputed. The most common explanation is that Grand Teton means large teat in French, however, other historians disagree, and claim that the mountain was named after the Teton Sioux tribe of Native Americans. There is a disagreement over who first climbed Grand Teton, nathaniel P. Langford and James Stevenson claimed to have reached the summit on July 29,1872. However, some believe their description and sketches match the summit of The Enclosure, the Enclosure is named after a man-made palisade of rocks on its summit, probably constructed by Native Americans. Owen reached the summit in 1898, in all likelihood, The Enclosure was first climbed by Native Americans as suggested by Langford in 1873. Supporters of Owen included The Wyoming Legislature and Paul Petzoldt, former pioneer American climber, ironically among Langfords supporters was Franklin Spalding, who led the ascent to the summit and tossed the rope that allowed Owen and the others to follow. Mountaineer and author Leigh Ortenburger researched the controversy in depth, using source material. First Male Alpine Descent-Bill Briggs,1971 First Female Alpine Descent- Kristen Ulmer,1997 First Male Telemark Descent- Rick Wyatt,1982 First Female Telemark Descent- A. J. Cargill,2004, First Male Snowboard Descent- Stephen Koch,1989 First Female Snowboard Descent- Dani deRuyter,2010 Grand Teton can be climbed via the Owen-Spalding route. The Owen-Spalding route is named for the climbers who claim to have made the first ascent, William Owen, Franklin Spalding, Frank Peterson, there is some debate as to which group made the first ascent, see that discussion. Notwithstanding the first-ascent controversy, this route has been firmly named after William Owen. The Owen-Spalding route begins at the Lower Saddle which is reached by walking from the Lupine Meadows Trailhead to Garnet Canyon, the more technical & exposed part of the climb begins at the Upper Saddle. The most popular route up the mountain is via the Upper Exum Ridge Route on the Exum Ridge, much of the climbing is fourth class, with one wide step from the end of Wall Street Ledge to the Ridge comprising the first stretch of technical climbing

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

North American Vertical Datum of 1988
–
NAVD88 was established in 1991 by the minimum-constraint adjustment of geodetic leveling observations in Canada, the United States, and Mexico. It held fixed the height of the tidal bench mark, referenced to the International Great Lakes Datum of 1985 local mean sea level height value, at Rimouski, Quebec. The definition of NAVD88 uses the Helmert orthometric height, which calculates the location of the geoid from modeled local gravity, the NAVD88 model is based on then-available measurements, and remains fixed despite later improved geoid models. NAVD88 replaced the National Geodetic Vertical Datum of 1929, previously known as the Sea Level Datum of 1929, the elevation difference between points in a local area will show negligible change from one datum to the other, even though the elevation of both does change. NGVD29 used a model of gravity based on latitude to calculate the geoid and did not take into account other variations. Thus, the difference for points across the country does change between datums.

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

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

Grand Teton National Park
–
Grand Teton National Park is a United States National Park in northwestern Wyoming. At approximately 310,000 acres, the park includes the peaks of the 40-mile-long Teton Range as well as most of the northern sections of the valley known as Jackson Hole. It is only 10 miles south of Yellowstone National Park, to which it is connected by the National Park Service-managed John D. Rockefeller, in the early 19th century, the first White explorers encountered the eastern Shoshone natives. Between 1810 and 1840, the region attracted fur trading companies that vied for control of the beaver pelt trade. U. S. Government expeditions to the commenced in the mid-19th century as an offshoot of exploration in Yellowstone. Efforts to preserve the region as a national park commenced in the late 19th century, against public opinion and with repeated Congressional efforts to repeal the measures, much of Jackson Hole was set aside for protection as Jackson Hole National Monument in 1943. The monument was abolished in 1950 and most of the monument land was added to Grand Teton National Park, Grand Teton National Park is named for Grand Teton, the tallest mountain in the Teton Range. The naming of the mountains is attributed to early 19th-century French-speaking trappers—les trois tétons was later anglicized and shortened to Tetons. At 13,775 feet, Grand Teton abruptly rises more than 7,000 feet above Jackson Hole, almost 850 feet higher than Mount Owen, the second-highest summit in the range. The park has numerous lakes, including 15-mile-long Jackson Lake as well as streams of varying length, though in a state of recession, a dozen small glaciers persist at the higher elevations near the highest peaks in the range. Some of the rocks in the park are the oldest found in any U. S. National Park and have been dated at nearly 2.7 billion years. Grand Teton National Park is an almost pristine ecosystem and the species of flora. More than 1,000 species of plants, dozens of species of mammals,300 species of birds, more than a dozen fish species. Grand Teton National Park is a destination for mountaineering, hiking, fishing. There are more than 1,000 drive-in campsites and over 200 miles of hiking trails provide access to backcountry camping areas. Noted for world-renowned trout fishing, the park is one of the few places to catch Snake River fine-spotted cutthroat trout, Grand Teton has several National Park Service-run visitor centers, and privately operated concessions for motels, lodges, gas stations and marinas. Paleo-Indian presence in what is now Grand Teton National Park dates back more than 11,000 years, along the shores of Jackson Lake, fire pits, tools and what are thought to have been fishing weights have been discovered. One of the tools found is of an associated with the Clovis culture

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

Breast-shaped hill
–
A breast-shaped hill is a mountain in the shape of a human breast. Some such hills are named Pap, a word for the breast or nipple, mostly breast-shaped hills are connected with local ancestral veneration of the breast as a symbol of fertility and well-being. Travelers and cartographers in colonial times often changed the names of such hills. Mamelon is a French name for a breast-shaped hillock, fort Mamelon was a famous hillock fortified by the Russians and captured by the French as part of the Siege of Sevastopol during the Crimean War of the 1850s. The word mamelon is also used in volcanology to describe a particular formation of volcanic origin. The term was coined by the French explorer and naturalist Jean Baptiste Bory de Saint-Vincent, african Great Lakes Mount Elgon on the Uganda-Kenya border Sweet Sixteen, Matthews Range, Laikipia district, Rift Valley Province, northern Kenya.

Shoshone people
–
The Shoshone were sometimes called the Snake Indians by neighboring tribes and early American explorers. Their peoples have become members of recognized tribes throughout their traditional areas of settlement, often colocated with the Paiute. The name Shoshone comes from Sosoni, a Shoshone word for high-growing grasses, some neighboring tribes call the Shoshone Grass House People, based on their traditional homes made from soshoni. Shoshones call themselves Newe, meaning People, meriwether Lewis recorded the tribe as the Sosonees or snake Indians in 1805. The Shoshoni language is spoken by approximately 1,000 people today and it belongs to the Central Numic branch of the Uto-Aztecan language family. Speakers are scattered from central Nevada to central Wyoming, the largest numbers of Shoshoni speakers live on the federally recognized Duck Valley Indian Reservation, located on the border of Nevada and Idaho, and Goshute Reservation in Utah. Idaho State University also offers Shoshoni-language classes, the Shoshone are a Native American tribe, who originated in the western Great Basin and spread north and east into present-day Idaho and Wyoming. By 1500, some Eastern Shoshone had crossed the Rocky Mountains into the Great Plains, after 1750, warfare and pressure from the Blackfoot, Crow, Lakota, Cheyenne, and Arapaho pushed Eastern Shoshone south and westward. Some of them moved as far south as Texas, emerging as the Comanche by 1700, as more European-American settlers migrated west, tensions rose with the indigenous people over competition for territory and resources. Wars occurred throughout the half of the 19th century. The Northern Shoshone, led by Chief Pocatello, fought during the 1860s with settlers in Idaho, as more settlers encroached on Shoshone hunting territory, the natives raided farms and ranches for food, and attacked immigrants. The warfare resulted in the Bear River Massacre, when US forces attacked and killed an estimated 410 Northwestern Shoshone, a large number of the dead were civilians, including women and children, deliberately killed by the soldiers. This was the highest number of deaths which the Shoshone suffered at the hands of United States forces, allied with the Bannock, to whom they were related, the Shoshone fought against the United States in the Snake War from 1864 to 1868. They fought US forces together in 1878 in the Bannock War, in 1876, by contrast, the Shoshone fought alongside the U. S. Army in the Battle of the Rosebud against their traditional enemies, the Lakota and Cheyenne. In 1879 a band of approximately 300 Eastern Shoshone became involved in the Sheepeater Indian War and it was the last Indian war fought in the Pacific Northwest region of the present-day United States. In 1911 a small group of Bannock under a leader named Mike Daggett, also known as Shoshone Mike, killed four ranchers in Washoe County, the settlers formed a posse and went out after the Native Americans. They caught up with the Bannock band on February 26,1911 and they lost one man of the posse, Ed Hogle. The posse captured three children and a woman, a rancher donated the partial remains of three adult males, two adult females, two adolescent males, and three children to the Smithsonian Institution in Washington, DC for study

Cathedral Group
–
The Cathedral Group is a term applied to a collection of most of the tallest mountains of the Teton Range, all of which are located in Grand Teton National Park, in the U. S. state of Wyoming. The collection of known as the Cathedral Group are classic alpine peaks. The highest peak in the group is Grand Teton, which more than 7,000 feet above Jackson Hole valley. The Cathedral Group is separated by tall peaks of the range by the Cascade Canyon to the north and Death Canyon to the south. Half the remaining glaciers in the Teton Range are located in this cluster of high peaks. Other glaciers such as the Middle Teton Glacier, Teepe Glacier, the Cathedral Group has several high cirques, arêtes as well as hanging and U-shaped valleys which are all the work of glacial activity. A few high altitude lakes can also be scattered among the peaks. Jackson, Reynold G. Park of the Matterhorns

Mount Owen (Wyoming)
–
Mount Owen is the second highest peak in the Teton Range, Grand Teton National Park in the U. S. state of Wyoming. The peak is named after William O. Owen, who organized the first documented ascent of the Grand Teton in 1898, Mount Owen is part of the Cathedral Group of high Teton peaks, a collection of peaks in the central section of the range that are particularly rugged. The 40-mile long Teton Range is the youngest mountain chain in the Rocky Mountains, several periods of glaciation have carved Mount Owen and the other peaks of the range into their current shapes. Valhalla Canyon is situated on the west slopes of Mount Owen, after two failed attempts in 1927 and one in 1928, Mount Owen was first climbed in 1930, and was one of the last of the major Teton peaks to be climbed. Numerous routes have been explored, ranging in difficulty from Class 5.1 to 5.10 Geology of the Grand Teton area

Teewinot Mountain is the sixth highest peak in the Teton Range, Grand Teton National Park, Wyoming. The name of the mountain is derived from the Shoshone Native American word meaning many pinnacles, the peak is northeast of the Grand Teton, and the two are separated from one another by the Teton Glacier and Mount Owen. Teewinot Mountain rises more than 5,500 feet above Jenny Lake, the 40 miles long Teton Range is the youngest mountain chain in the Rocky Mountains, and began their uplift 9 million years ago, during the Miocene. Several periods of glaciation have carved Teewinot Mountain and the peaks of the range into their current shapes. Broken Falls is one of the tallest cascades in Grand Teton National Park, Teewinot Mountain is most easily ascended via the eastern face, which finishes with a somewhat exposed Class 4 scramble to the tiny summit. An unmarked climbers trail, known as the Apex Trail, leads most of the way up the mountain from the Lupine Meadows area, geology of the Grand Teton area

Middle Teton is the third highest peak in the Teton Range, Grand Teton National Park, Wyoming. The peak is immediately southwest of Grand Teton and the two are separated from one another by the saddle, a broad high ridge at 11,600 feet. The Middle Teton Glacier is located on the slopes of the peak. Middle Teton is a pyramidal shaped alpine peak and is sometimes included as part of the Cathedral Group of high Teton peaks. The 40-mile long Teton Range is the youngest mountain chain in the Rocky Mountains, several periods of glaciation have carved Middle Teton and the other peaks of the range into their current shapes. From the lower saddle, a feature known as the black dike appears as a straight line running from near the top of the mountain down 800 feet. The black dike is an intrusion that occurred long after the surrounding rock was formed. The first recorded ascent of Middle Teton was by Albert R. Ellingwood on August 23,1923, Ellingwood made the first ascent of South Teton the same day. What is known as the southwest couloir provides the easiest route to the summit, other sections on the mountain are rated as high as class 5.11, with the Middle Teton Glacier route considered to be the most technically advanced. The first ascent of the Glacier Route was completed on August 4,1944, by Paul Bradt and this route is described as a classic, and is one of the few early season purely ice and snow routes in the Teton Range.

South Teton is the fifth highest peak in the Teton Range, Grand Teton National Park, Wyoming. The peak is south of Middle Teton and just west of Cloudveil Dome and is part of the Cathedral Group of high Teton peaks. The 40 miles long Teton Range is the youngest mountain chain in the Rocky Mountains, several periods of glaciation have carved South Teton and the other peaks of the range into their current shapes. South Teton was first climbed on August 29,1923 by Albert R. Ellingwood, Ellingwood made the first ascent of Middle Teton the same day. Davis was the first woman to ascend Grand Teton, the easiest climbing route is via Garnet Canyon to an altitude of 9,200 feet. From there a trail leads southwest towards a pass between South and Middle Teton, most ascents of the summit are made from this pass. A number of difficult ascents are also done by experienced climbers. Geology of the Grand Teton area Breast shaped hill

Mount Moran
–
Mount Moran is a mountain in Grand Teton National Park of western Wyoming, USA. The mountain is named for Thomas Moran, an American western frontier landscape artist, Mount Moran dominates the northern section of the Teton Range rising 6,000 feet above Jackson Lake. Several active glaciers exist on the mountain with Skillet Glacier plainly visible on the monolithic east face, like the Middle Teton in the same range, Mount Morans face is marked by a distinctive basalt intrusion known as the Black Dike. Mount Moran is a massive and impressive mountain which would make it attractive to mountaineers, however, the comparative difficulty of the approach to the climbs makes it a much less popular climb than the Grand Teton and other peaks to the south. Instead, most climbers choose to canoe from String Lake, across Leigh Lake and then pick their way to their respective route, as a result, most climbs on Mount Moran tend to take several days even when the technical portion of the climb is comparatively brief. The first ascent of Mount Moran was made on July 22,1922 by LeGrand Hardy, Bennet McNulty, rich of the Chicago Mountaineering Club via the Skillet Glacier route. The Skillet Glacier still provides perhaps the easiest and most direct route to the summit and is rated 5.4. As the name implies, most of the climb is on the snow and ice of Skillet Glacier. The most popular route up Mount Moran is the CMC route, the CMC is rated 5.5, and ascends the east face just south of the Black Dike. The CMC climbs good rock and is free of snow. It also has the advantage of a good camp high on the flank of the mountain, the Direct South Buttress route, rated 5.7 A3, is recognized in the historic climbing text Fifty Classic Climbs of North America and considered a classic around the world. On November 21,1950, a C-47 cargo plane owned by the New Tribes Mission crashed on Mount Moran during a storm, killing all 21 on board. A rescue party organized by Paul Petzoldt located the wreckage on November 25, the wreckage remains on the mountain today, but the Park Service discourages direct climbs to the site.

Buck Mountain 11,938 feet is located in the Teton Range, Grand Teton National Park, Wyoming, immediately southeast of Grand Teton. The mountain is the highest summit south of Garnet Canyon and is seen from most vantage points in Jackson Hole. Views from the summit offer excellent views of the Cathedral Group to the north, timberline Lake is located on the eastern flanks of the peak. The summit was first climbed on August 21,1898 by T. M, bannon and George Buck, only ten days after Grand Teton was first climbed by another party. Bannon later became the first person to climb Borah Peak, the tallest mountain in the state of Idaho

Geology of the Grand Teton area
–
The geology of the Grand Teton area consists of some of the oldest rocks and one of the youngest mountain ranges in North America. The Teton Range, mostly located in Grand Teton National Park, an older feature, Jackson Hole, is a basin that sits aside the range. The 2.5 billion year old metamorphic rocks make up the east face of the Tetons are marine in origin. These same rocks are buried deep inside Jackson Hole. Perhaps 3,000 million years ago in Precambrian time, sand, limey ooze, silt, interbeded between these layers were volcanic deposits, probably from an island arc. These sediments were lithified into sandstones, limestones, and various shales. Today these rocks dominate the Teton Range with good examples easily viewable in Death Canyon, the green to black serpentine created was used by Native Americans to make bowls. Sometime around 2,500 million years ago, blobs of magma intruded into the older rock, extensive exposures of this rock are found in the central part of the range. Some of the large dikes can be seen from the Jenny Lake, more than 700 million years elapsed between intrusion of the black dikes and deposition of the first Paleozoic sedimentary rocks. Deposition resumed in the Cambrian period and continued through the Paleozoic era and this unit was laid down in a shallow sea and later became a discontinuous mix of dolomite, limestone, sandstones, and shales. The layers of this unit are relatively undeformed for their age even though periodic upwarp exposed them to erosion, fossilized brachiopods, bryozoans, corals, and trilobites are found in the carbonate rock layers with the best examples found outside the park in the Alaska Basin. The most complete examples of this unit are found to the west, north, early in Cambrian time a shallow seaway, called the Cordilleran trough, extended from southern California northeastward across Nevada into Utah and Idaho. The vast gently rolling plain on Precambrian rocks to the east was drained by sluggish westward-flowing rivers that carried sand, the site of the Teton Range was part of this plain. Slow subsidence of the land caused the sea to spread eastward during Middle Cambrian time flooding the Precambrian plain. Sand accumulated along the beaches just as it does today, as the sea moved still farther east, mud was deposited on the now-submerged beach sand. In the Teton area, the oldest sand deposit is the 175 to 200 feet thick Flathead Sandstone, the partly marine Flathead Sandstone is reddish-brown, very hard, brittle and exposures can be found on the north and west flanks of the Teton Range and Gros Ventre Range. Mud was laid down on top of the Flathead Sandstone as the shoreline advanced eastward across the Teton area, the resulting soft greenish-gray shale with beds of purple and green sandstone near its base, became the 100 feet thick Wolsey Shale Member of the Gros Ventre Formation. Some shale shows patterns of cracks that formed when the mud was briefly exposed to the air along tidal flats

Geologic fault
–
In geology, a fault is a planar fracture or discontinuity in a volume of rock, across which there has been significant displacement as a result of rock-mass movement. Large faults within the Earths crust result from the action of tectonic forces. Energy release associated with movement on active faults is the cause of most earthquakes. A fault plane is the plane that represents the surface of a fault. A fault trace or fault line is the intersection of a plane with the ground surface. A fault trace is also the line commonly plotted on maps to represent a fault. Since faults do not usually consist of a single, clean fracture, the two sides of a non-vertical fault are known as the hanging wall and footwall. By definition, the wall occurs above the fault plane. This terminology comes from mining, when working a tabular ore body, because of friction and the rigidity of rocks, they cannot glide or flow past each other easily, and occasionally all movement stops. A fault in ductile rocks can also release instantaneously when the rate is too great. The energy released by instantaneous strain-release causes earthquakes, a common phenomenon along transform boundaries, slip is defined as the relative movement of geological features present on either side of a fault plane, and is a displacement vector. A faults sense of slip is defined as the motion of the rock on each side of the fault with respect to the other side. In practice, it is only possible to find the slip direction of faults. Based on direction of slip, faults can be categorized as, strike-slip. Dip-slip, offset is predominantly vertical and/or perpendicular to the fault trace, oblique-slip, combining significant strike and dip slip. The fault surface is usually vertical and the footwall moves either left or right or laterally with very little vertical motion. Strike-slip faults with left-lateral motion are known as sinistral faults. Those with right-lateral motion are known as dextral faults

Jackson Hole
–
Jackson Hole is a valley between the Teton Mountain Range and the Gros Ventre Range in Wyoming. These low-lying valleys surrounded by mountains and containing rivers and streams are habitat for beaver and other fur-bearing animals. The town of Jackson was named in late 1893 by Margaret Simpson and she named the town in order for easterners to be able to forward mail west. Jackson, which incorporated in 1914, was named after David Edward Davey Jackson who trapped beaver in the area in the late 1820s while a partner in the firm of Smith. Davy Jackson was one of the first white men to spend a winter in the Valley of the Teton Mountains. Though used by Native Americans for hunting and ceremonial purposes, the valley was not known to harbor year-round human settlement prior to the 1870s. Descriptions of the valley and its features were recorded in the journals of John Colter, after returning to the Rocky Mountains, Colter entered the region in 1807 in the vicinity of Togwotee Pass and became the first white American to see the valley. His reports of the valley, the Teton Range and the Yellowstone region to the north were viewed by people of the day with skepticism, the first people to settle the region were Native Americans, then fur trappers, and then homesteaders. Because the soil is not ideal for raising crops, the valley was used for cattle, tourism quickly became popular with the establishment of dude ranches. The only incorporated town in the valley is Jackson, also called Jackson Hole, other communities in the valley include Wilson, Teton Village, Moran Junction, Hoback, Moose, and Kelly. West of Jackson, Teton Pass crosses the end of the Teton Range, providing access to Victor and Driggs in eastern Idaho and Alta, Wyoming. This area was known as Pierres Hole and hosted a major Rendezvous in 1832, numerous elk use the valley as grazing range during the winter, and sleigh rides are offered to tourists. The Jackson Hole Mountain Resort, Snow King and Grand Targhee Resort ski areas, the valley is formed by the Teton Range on the western side and the Gros Ventre Range on the eastern side. Grand Teton National Park occupies the part of the valley encompassing much of the Teton Range as well as Jackson Lake. The town of Jackson is at the southern end. Between them lies, on U. S. Route 26, Glacier View Turnout offering a view of Teton Glacier on the north of Grand Teton, and the National Elk Refuge, home of the largest elk herd on earth. The Snake River threads through the valley from its headwater in Yellowstone in the north to the mouth of the Snake River Canyon at the southern tip of the valley. Blacktail Butte is a prominent landform rising from the valley floor, the average elevation of the valley is over 6,500 feet above sea level

Gneiss
–
Gneiss is a common distributed type of rock formed by high-grade regional metamorphic processes from pre-existing formations that were originally either igneous or sedimentary rocks. The foliations are characterized by alternating darker and lighter colored bands, the word gneiss comes from the Middle High German verb gneist. It has occurred in English since at least 1757, gneissic rocks are usually medium- to coarse-foliated, they are largely recrystallized but do not carry large quantities of micas, chlorite or other platy minerals. Gneisses that are metamorphosed igneous rocks or their equivalent are termed granite gneisses, diorite gneisses, gneiss rocks may also be named after a characteristic component such as garnet gneiss, biotite gneiss, albite gneiss, etc. Orthogneiss designates a gneiss derived from a rock, and paragneiss is one from a sedimentary rock. Gneissose rocks have properties similar to gneiss, gneiss appears to be striped in bands, called gneissic banding. The banding is developed under high temperature and pressure conditions, the minerals are arranged into layers that appear as bands in cross section. The appearance of layers, called compositional banding, occurs because the layers, the darker bands have relatively more mafic minerals. The lighter bands contain relatively more felsic and these forces stretch out the rock like a plastic, and the original material is spread out into sheets. Another cause of banding is metamorphic differentiation, which separates different materials into different layers through chemical reactions, not all gneiss rocks have detectable banding. In kyanite gneiss, crystals of kyanite appear as random clumps in what is mainly a plagioclase matrix, henderson gneiss is found in North Carolina and South Carolina, US, east of the Brevard Shear Zone. It has deformed into two sequential forms, the second, more warped, form is associated with the Brevard Fault, and the first deformation results from displacement to the southwest. Most of the Outer Hebrides of Scotland have a formed from Lewisian gneiss. In addition to the Outer Hebrides, they form basement deposits on the Scottish mainland west of the Moine Thrust and on the islands of Coll and Tiree. These rocks are igneous in origin, mixed with metamorphosed marble, quartzite and mica schist with later intrusions of basaltic dikes. Gneisses of Archean and Proterozoic age occur in the Baltic Shield, in antiquity, gneisses were also utilized in architectural construction. They were used to erect the Sphinx of Taharqo in the Nile Valley, list of rock types Blatt, Harvey and Robert J. Tracy. Petrology, Igneous, Sedimentary and Metamorphic, 2nd ed.

Granite

Granite is a common type of felsic intrusive igneous rock that is granular and phaneritic in texture. Granites can be white, pink, or gray in color. The word granite comes from the Latin granum, a grain, in reference to the structure of such a holocrystalline rock. By definition, granite is a rock with at least 20% quartz. The term granitic means granite-like and is applied to granite and a group of igneous rocks with similar textures and slight variations in composition. Occasionally some individual crystals are larger than the groundmass, in case the texture is known as porphyritic. A granitic rock with a texture is known as a granite porphyry. Granitoid is a general, descriptive field term for lighter-colored, coarse-grained igneous rocks, petrographic examination is required for identification of specific types of granitoids. The extrusive igneous rock equivalent of granite is rhyolite, Granite is nearly always massive, hard and tough, and therefore it has gained widespread use throughout human history, and more recently as a construction stone. The average density of granite is between 2.65 and 2.75 g/cm3, its compressive strength usually lies above 200 MPa, and its viscosity near STP is 3–6 •1019 Pa·s. The melting temperature of dry granite at ambient pressure is 1215–1260 °C, it is reduced in the presence of water. Granite has poor primary permeability, but strong secondary permeability, true granite according to modern petrologic convention contains both plagioclase and alkali feldspars. When a granitoid is devoid or nearly devoid of plagioclase, the rock is referred to as alkali feldspar granite, when a granitoid contains less than 10% orthoclase, it is called tonalite, pyroxene and amphibole are common in tonalite. A granite containing both muscovite and biotite micas is called a binary or two-mica granite, two-mica granites are typically high in potassium and low in plagioclase, and are usually S-type granites or A-type granites. A worldwide average of the composition of granite, by weight percent, based on 2485 analyses. Much of it was intruded during the Precambrian age, it is the most abundant basement rock that underlies the relatively thin veneer of the continents. Outcrops of granite tend to form tors and rounded massifs, granites sometimes occur in circular depressions surrounded by a range of hills, formed by the metamorphic aureole or hornfels. Granite often occurs as small, less than 100 km² stock masses

Dike (geology)
–
A dike or dyke, in geological usage, is a sheet of rock that formed in a fracture in a pre-existing rock body. Dikes can be either magmatic or sedimentary in origin, magmatic dikes form when magma intrudes into a crack then crystallizes as a sheet intrusion, either cutting across layers of rock or through an unlayered mass of rock. Clastic dikes are formed when sediment fills a pre-existing crack, an intrusive dike is an igneous body with a very high aspect ratio, which means that its thickness is usually much smaller than the other two dimensions. Thickness can vary from sub-centimeter scale to many meters, and the dimensions can extend over many kilometres. A dike is an intrusion into an opening cross-cutting fissure, shouldering aside other pre-existing layers or bodies of rock, near-horizontal, or conformable intrusions, along bedding planes between strata are called intrusive sills. Sometimes dikes appear in swarms, consisting of several to hundreds of dikes emplaced more or less contemporaneously during a single intrusive event, the worlds largest dike swarm is the Mackenzie dike swarm in the Northwest Territories, Canada. Dikes often form as either radial or concentric swarms around plutonic intrusives, the latter are known as ring dikes. Pegmatite dikes comprise extremely coarse crystalline granitic rocks - often associated with granite intrusions or metamorphic segregations. Aplite dikes are fine-grained or sugary-textured intrusives of granitic composition, in contrast to magmatic dikes, a sill is a magmatic sheet intrusion that forms within and parallel to the bedding of layered rock. Sedimentary dikes or clastic dikes are vertical bodies of rock that cut off other rock layers. Driven by the pressure the sediment breaks through overlying layers. When a soil is under permafrost conditions the water is totally frozen. When cracks are formed in rocks, they may fill up with sediments that fall in from above. The result is a body of sediment that cuts through horizontal layers. Batholith Ring dike Fissure vent Laccolith Runamo, formerly interpreted as a runic inscription

Diabase
–
Diabase or dolerite or microgabbro is a mafic, holocrystalline, subvolcanic rock equivalent to volcanic basalt or plutonic gabbro. Diabase dikes and sills are typically shallow intrusive bodies and often exhibit fine grained to aphanitic chilled margins which may contain tachylite. Diabase normally has a fine, but visible texture of euhedral lath-shaped plagioclase crystals set in a matrix of clinopyroxene, typically augite, with minor olivine, magnetite. Accessory and alteration minerals include hornblende, biotite, apatite, pyrrhotite, chalcopyrite, serpentine, chlorite, the texture is termed diabasic and is typical of diabases. This diabasic texture is also termed interstitial, the feldspar is high in anorthite, the calcium endmember of the plagioclase anorthite-albite solid solution series, most commonly labradorite. Diabase is usually found in relatively shallow intrusive bodies such as dikes. Diabase dikes occur in regions of crustal extension and often occur in swarms of hundreds of individual dikes or sills radiating from a single volcanic center. The Palisades Sill which makes up the New Jersey Palisades on the Hudson River, parts of the Deccan Traps of India, formed at the end of the Cretaceous also includes dolerite. It is also abundant in parts of Curaçao, an island off the coast of Venezuela. West of the Norseman–Wiluna Belt is the Yalgoo–Singleton Belt, where complex dolerite dike swarms obscure the volcaniclastic sediments, large dolerite sills such as the Golden Mile Dolerite can exhibit course grained texture, and show a large diversity in petrography and geochemistry across the width of the sill. The vast areas of mafic volcanism/plutonism associated with the Jurassic breakup of Gondwanaland in the Southern Hemisphere include many large diabase/dolerite sills and dike swarms. These include the Karoo dolerites of South Africa, the Ferrar Dolerites of Antarctica, in Tasmania dolerite dominates much of the landscape, particularly alpine areas. Ring dikes are large, near vertical dikes showing above ground as circular outcrops up to 30 km in diameter, thicker dikes are made up of plutonic rocks, rather than hypabyssal and are centred on deep intrusions. Diabase is crushed and used as an aggregate for road beds, buildings, railroad beds. Diabase can also be cut for use as as ornamental stone for countertops, facing stone on buildings, a form of dolerite, known as bluestone, is one of the materials used as in the construction of Stonehenge. In Tasmania, being one of the most common rocks found, it has used as a building stone, for landscaping. List of rock types Collection of dikes in the Fish River Canyon, Namibia

Cambrian
–
The Cambrian Period was the first geological period of the Paleozoic Era, of the Phanerozoic Eon. The Cambrian lasted 55.6 million years from the end of the preceding Ediacaran Period 541 million years ago to the beginning of the Ordovician Period 485.4 mya and its subdivisions, and its base, are somewhat in flux. The period was established by Adam Sedgwick, who named it after Cambria, the Latinised form of Cymru, the Welsh name for Wales, as a result, our understanding of the Cambrian biology surpasses that of some later periods. The rapid diversification of lifeforms in the Cambrian, known as the Cambrian explosion, most of the continents were probably dry and rocky due to a lack of vegetation. Shallow seas flanked the margins of several continents created during the breakup of the supercontinent Pannotia, the seas were relatively warm, and polar ice was absent for much of the period. The United States Federal Geographic Data Committee uses a barred capital C ⟨Є⟩ character similar to the capital letter Ukrainian Ye ⟨Є⟩ to represent the Cambrian Period, the proper Unicode character is U+A792 Ꞓ LATIN CAPITAL LETTER C WITH BAR. Despite the long recognition of its distinction from younger Ordovician Period rocks and older Supereon Precambrian rocks, the base of the Cambrian lies atop a complex assemblage of trace fossils known as the Treptichnus pedum assemblage. Pedum in Namibia, Spain and Newfoundland, and possibly, in the western USA, the stratigraphic range of T. pedum overlaps the range of the Ediacaran fossils in Namibia, and probably in Spain. The Cambrian Period followed the Ediacaran Period and was followed by the Ordovician Period, the Cambrian is divided into four epochs and ten ages. Currently only two series and five stages are named and have a GSSP, because the international stratigraphic subdivision is not yet complete, many local subdivisions are still widely used. In some of these subdivisions the Cambrian is divided into three epochs with locally differing names – the Early Cambrian, Middle Cambrian and Furongian, rocks of these epochs are referred to as belonging to the Lower, Middle, or Upper Cambrian. Trilobite zones allow biostratigraphic correlation in the Cambrian, each of the local epochs is divided into several stages. The International Commission on Stratigraphy list the Cambrian period as beginning at 541 million years ago, the lower boundary of the Cambrian was originally held to represent the first appearance of complex life, represented by trilobites. The recognition of small shelly fossils before the first trilobites, and Ediacara biota substantially earlier and this formal designation allowed radiometric dates to be obtained from samples across the globe that corresponded to the base of the Cambrian. Early dates of 570 million years ago quickly gained favour, though the used to obtain this number are now considered to be unsuitable. A more precise date using modern radiometric dating yield a date of 541 ±0.3 million years ago, most continental land was clustered in the Southern Hemisphere at this time, but was drifting north. Large, high-velocity rotational movement of Gondwana appears to have occurred in the Early Cambrian, the sea levels fluctuated somewhat, suggesting there were ice ages, associated with pulses of expansion and contraction of a south polar ice cap. In Baltoscandia a Lower Cambrian transgression transformed large swathes of the Sub-Cambrian peneplain into a epicontinental sea, the Earth was generally cold during the early Cambrian, probably due to the ancient continent of Gondwana covering the South Pole and cutting off polar ocean currents

Paleozoic
–
The Paleozoic Era is the earliest of three geologic eras of the Phanerozoic Eon, from 541 to 252.17 million years ago. It is the longest of the Phanerozoic eras, and is subdivided into six periods, the Cambrian, Ordovician, Silurian, Devonian, Carboniferous. The Paleozoic comes after the Neoproterozoic era of the Proterozoic and is followed by the Mesozoic, the Paleozoic was a time of dramatic geological, climatic, and evolutionary change. The Cambrian witnessed the most rapid and widespread diversification of life in Earths history, known as the Cambrian explosion, fish, arthropods, amphibians, anapsids, synapsids, euryapsids and diapsids all evolved during the Paleozoic. Life began in the ocean but eventually transitioned onto land, and by the late Paleozoic, Great forests of primitive plants covered the continents, many of which formed the coal beds of Europe and eastern North America. Towards the end of the era, large, sophisticated diapsids and synapsids were dominant, the Paleozoic Era ended with the largest extinction event in the history of Earth, the Permian–Triassic extinction event. The effects of this catastrophe were so devastating that it took life on land 30 million years into the Mesozoic Era to recover, recovery of life in the sea may have been much faster. The Paleozoic era began and ended with supercontinents and in between were the rise of mountains along the margins, and flooding and draining of shallow seas between. At its start, the supercontinent Pannotia broke up, paleoclimatic studies and evidence of glaciers indicate that central Africa was most likely in the polar regions during the early Paleozoic. During the early Paleozoic, the huge continent Gondwana formed or was forming, by mid-Paleozoic, the collision of North America and Europe produced the Acadian-Caledonian uplifts, and a subduction plate uplifted eastern Australia. There are six periods in the Paleozoic Era, Cambrian, Ordovician, Silurian, Devonian, Carboniferous, the Cambrian spans from 541 million years to 485 million years and is the first period of the Paleozoic era of the Phanerozoic. The Cambrian marked a boom in evolution in an event known as the Cambrian explosion in which the largest number of creatures evolved in any period of the history of the Earth. Creatures like algae evolved, but the most ubiquitous of that period were the armored arthropods, almost all marine phyla evolved in this period. During this time, the supercontinent Pannotia begins to break up, the Ordovician spanned from 485 million years to 443 million years ago. The Ordovician is a time in Earths history in many of the biological classes still prevalent today evolved, such as primitive fish, cephalopods. The most common forms of life, however, were trilobites, snails, more importantly, the first arthropods went ashore to colonize the empty continent of Gondwana. By the end of the Ordovican, Gondwana was at the pole, early North America had collided with Europe. Glaciation of Africa resulted in a drop in sea level

Cenozoic
–
The Cenozoic Era is the current and most recent of the three Phanerozoic geological eras, following the Mesozoic Era and covering the period from 66 million years ago to the present day. The Cenozoic is also known as the Age of Mammals, because of the mammals that dominated, such as Entelodont, Paraceratherium. The extinction of many large groups such as non-avian dinosaurs, Plesiosauria and Pterosauria allowed the mammals and birds to greatly diversify. Early in the Cenozoic, following the K-Pg event, the planet was dominated by relatively small fauna, including mammals, birds, reptiles. From a geological perspective, it did not take long for mammals, some flightless birds grew larger than humans. These species are referred to as terror birds, and were formidable predators. Mammals came to occupy almost every available niche, and some also grew very large, the Earths climate had begun a drying and cooling trend, culminating in the glaciations of the Pleistocene Epoch, and partially offset by the Paleocene-Eocene Thermal Maximum. The continents also began looking roughly familiar at this time and moved into their current positions. The Cenozoic is divided into three periods, the Paleogene, Neogene, and Quaternary, and seven epochs, the Paleocene, Eocene, Oligocene, Miocene, Pliocene, Pleistocene, and Holocene. The common use of epochs during the Cenozoic helps paleontologists better organize, there is also more detailed knowledge of this era than any other because of the relatively young, well-preserved rocks associated with it. The Paleogene spans from the extinction of dinosaurs,66 million years ago. It features three epochs, the Paleocene, Eocene and Oligocene, the Paleocene ranged from 66 million to 56 million years ago. The Paleocene is a point between the devastation that is the K-T extinction, to the rich jungles environment that is the Early Eocene. The Early Paleocene saw the recovery of the earth, the continents began to take their modern shape, but all the continents and subcontinent India were separated from each other. Afro-Eurasia was separated by the Tethys Sea, and the Americas were separated by the strait of Panama and this epoch featured a general warming trend, with jungles eventually reaching the poles. The oceans were dominated by sharks as the large reptiles that had once ruled became extinct, archaic mammals filled the world such as creodonts and early primates that evolved during the Mesozoic, and as a result, there was nothing over 10 kilograms. The Eocene Epoch ranged from 56 million years to 33.9 million years ago, in the Early-Eocene, life was small and lived in cramped jungles, much like the Paleocene. There was nothing over the weight of 10 kilograms, among them were early primates, whales and horses along with many other early forms of mammals

Foothills
–
Foothills are geographically defined as gradual increase in elevation at the base of a mountain range, higher hill range or an upland area. They are a zone between plains and low relief hills to the adjacent topographically higher mountains, hills, and uplands. Foothills primarily border mountains, especially those which are reached through low ridges that increase in size closer and closer to the mountain, generally the area from Ferntree Gully/Boronia/The Basin through to Belgrave. Another word for a region is piedmont, derived from foot of the mount in Romance languages. The Piedmont region of Italy lies in the foothills of the Alps and they are also known as submontane zones, especially when referring to montane ecosystems

Teton Fault
–
The Teton fault is a normal fault located in northwestern Wyoming. The fault has a length of 44 miles and runs along the base of the Teton Range. Vertical movement on the fault has caused the dramatic topography of the Teton Range, the Teton fault is located in a unique geologic setting. The fault is on the boundary of four major provinces, the Basin and Range, Idaho-Wyoming Thrust belt, Rocky Mountain Foreland. The Basin and Range province is a region of east-west crustal extension and this province adds tension perpendicular to the fault line causing the fault blocks to move apart. The Idaho-Wyoming Thrust belt is located south of the Teton fault and is a region of thick, the Rocky Mountain Foreland is located east of the Teton fault and is a region of thicker crust. This section of crust is heavier and adds to the downward force on the hanging wall of fault. The Yellowstone volcanic plateau is a region of uplift and expansion that influences both vertical and horizontal forces on the Teton fault, the Teton fault is unique in that it dips or slopes to the east. The majority of major faults in the Basin and Range province dip to the west, the unique dip of the Teton fault can be explained by the subsidence of the Snake River Plain. The Snake River Plain is located to the west of the Teton fault and was formed by the migration of the Yellowstone caldera across southern Idaho, as this section of crust cools it tends to subside causing the footwall of the fault to tilt down toward the west. The Teton fault is also an important feature in a region of seismic activity called the Intermountain Seismic Belt. This region extends from western Montana south to northern Arizona, the development of the Teton fault has been influenced by many past geologic events. In the Precambrian, extensive plutonism caused metamorphism and deformation of the region that would become the Teton Range, during the Mesozoic and early Tertiary, the region underwent compression and crustal thickening. This formed thrust faults and folds, in the Late Tertiary, compressional forces ceased and extensional forces began. This led to the development of the Basin and Range province beginning 20–17 million years ago, the age of the Teton fault is somewhat controversial. Most estimates range between 2 and 13 million years old with a consensus that most of the movement on the occurred within the last 2 million years. Rates of movement on the fault have changed throughout time, at the end of the Pinedale glaciation 16,000 to 14,000 years ago, slip on the fault increased. This was likely due to changing stresses on the fault as glaciers melted, the largest known earthquakes on the fault in recent history occurred around 4800 and 8000 years ago

Snake River
–
The Snake River is a major river of the greater Pacific Northwest in the United States. At 1,078 miles long, it is the largest tributary of the Columbia River and its drainage basin encompasses parts of six U. S. states, and its average discharge is over 54,000 cubic feet per second. Rugged mountains divided by rolling plains characterize the physiographically diverse watershed of the Snake River, the Snake River Plain was created by a volcanic hotspot which now lies underneath Yellowstone National Park, where the headwaters of the Snake River arise. Two of these flooding events significantly affected the river and its surrounds. More than 11,000 years ago, prehistoric Native Americans lived along the Snake, Salmon from the Pacific Ocean spawned by the millions in the river. These fish were central to the lives of the people along the Snake below Shoshone Falls, by the time Lewis and Clark crossed the Rockies and sighted the valley of a Snake tributary, the Nez Perce and Shoshone were the most powerful peoples in the region. Some tribes adopted use of horses after contact with Europeans, which reshaped their hunting, later explorers and fur trappers further changed and used the resources of the Snake River basin. At one point, a sign made by the Shoshones representing fish was misinterpreted to represent a snake. By the middle 19th century, the Oregon Trail, a trail of which a major portion followed the Snake River, had been established by aspiring settlers and traders. Steamboats and railroads moved agricultural products and minerals along the river throughout the 19th, several of these have been proposed for removal in order to restore some of the rivers once-tremendous salmon runs. Its first 50-mile run through the valley of Jackson Hole, which cuts between the Teton Range and the Continental Divide, there it is also met by the Salt River at the mouth of Star Valley. Southwest of the city of Rexburg, the Snake receives from the right the Henrys Fork, the confluence with the Henrys Fork takes the river southwards through downtown Idaho Falls, rounding the Fort Hall Indian Reservation and into American Falls Reservoir, receiving the Portneuf River. Close to Twin Falls, the Snake approaches the southernmost point in its entire course, after which it starts to flow generally northwest. Shortly after it passes within 30 miles of the Idaho state capital of Boise, there were hundreds of rapids in Hells Canyon, some of which have been stilled by the three dams of the Hells Canyon Hydroelectric Project, Hells Canyon, Oxbow, and Brownlee. The Salmon River, the largest tributary of the Snake River, meets it in one of the most remote areas of its entire course, the confluence of the Snake and Columbia rivers has been submerged in Lake Wallula, the reservoir of McNary Dam. The Columbia River flows about 325 miles further west to the Pacific Ocean, as recently as 165 million years ago, most of western North America was still part of the Pacific Ocean. Even larger lava flows of Columbia River basalts issued over eastern Washington, forming the Columbia Plateau southeast of the Columbia River, separate volcanic activity formed the northwestern portion of the plain, an area far from the path of the hotspot which now lies beneath Yellowstone National Park. At this point, the Snake River watershed was beginning to take shape, the Snake River Plain and the gap between the Sierra Nevada and Cascade Range formed a moisture channel, running as far inland as the headwaters of the Snake River

John Wayne
–
Marion Mitchell Morrison, known professionally as John Wayne and nicknamed Duke, was an American actor and filmmaker. An Academy Award-winner for True Grit, Wayne was among the top box office draws for three decades, born in Winterset, Iowa, Wayne grew up in Southern California. He found work at film studios when he lost his football scholarship to the University of Southern California as a result of a bodysurfing accident. Initially working for the Fox Film Corporation, he appeared mostly in bit parts. His first leading role came in Raoul Walshs The Big Trail, Waynes career took off in 1939, with John Fords Stagecoach making him an instant star. He went on to star in 142 pictures, biographer Ronald Davis said, John Wayne personified for millions the nations frontier heritage. Eighty-three of his movies were Westerns, and in them he played cowboys, cavalrymen and he is also remembered for his roles in The Quiet Man, Rio Bravo, and The Longest Day. In his final performance, he starred as an aging gunfighter battling cancer in The Shootist. He appeared with many important Hollywood stars of his era, Wayne was born Marion Robert Morrison on May 26,1907 at 224 South Second Street in Winterset, Iowa. The local paper, Winterset Madisonian, reported on page 4 of the edition of May 30,1907 that Wayne weighed 13 pounds at birth and his middle name was soon changed from Robert to Mitchell when his parents decided to name their next son Robert. Waynes father, Clyde Leonard Morrison, was the son of American Civil War veteran Marion Mitchell Morrison, Waynes mother, the former Mary Molly Alberta Brown, was from Lancaster County, Nebraska. Waynes ancestry included English, Irish, Scots-Irish, and Scottish, Waynes family moved to Palmdale, California, and then in 1916 to Glendale, California, where his father worked as a pharmacist. A local fireman at the station on his route to school in Glendale started calling him Little Duke because he never went anywhere without his huge Airedale Terrier and he preferred Duke to Marion, and the nickname stuck. Wayne attended Wilson Middle School in Glendale, as a teen, he worked in an ice cream shop for a man who shod horses for Hollywood studios. He was also active as a member of the Order of DeMolay and he played football for the 1924 league champion Glendale High School team. Wayne applied to the U. S. Naval Academy, and he instead attended the University of Southern California, majoring in pre-law. He was a member of the Trojan Knights and Sigma Chi fraternities, Wayne also played on the USC football team under coach Howard Jones. A broken collarbone injury curtailed his career, Wayne later noted that he was too terrified of Jones reaction to reveal the actual cause of his injury

The Big Trail
–
The Big Trail is a 1930 American pre-Code early widescreen movie shot on location across the American West starring John Wayne in his first leading role and directed by Raoul Walsh. A large caravan of settlers attempt to cross the Oregon Trail, at a large trading post owned by a man named Wellmore, Coleman sees Flack and suspects him right away as being one of the killers. Flack likewise suspects Coleman as being somebody who knows too much about the killing, Coleman agrees to scout for the train, so he can keep an eye on the villains and kill them as soon as they reach their destination. The caravan of settlers in their Prairie schooners would follow Wellmores ox-drawn train of Conestoga Wagons, the film is set somewhere between 1837 and 1845. This is historically accurate, as the first major wave of settlers on the Oregon Trail was in 1843, Coleman finds love with young Ruth Cameron, whom hed kissed accidentally, mistaking her for somebody else. Unwilling to accept her attraction toward him, Ruth gets rather close to an acquaintance of Flacks, Thorpe. Coleman and Flack have to lead the settlers west, while Flack does everything he can to have Coleman killed before he finds any proof of what hed done. The three villains main reason for going west is to avoid the hangmans noose for previous crimes, the settlers trail ends in the Willamette Valley of Oregon, where Coleman and Ruth finally settle down together amidst giant redwoods. After the film was given the greenlight by the producers at Fox Studios in early 1930, Walsh offered the lead to actor Gary Cooper, when Wayne professed inexperience, Walsh told him to just sit good on a horse and point. Filming began on-location just outside Santa Fe, New Mexico in April 1930, the film was shot in an early widescreen process using 70mm film called 70 mm Grandeur film, which was first used in the film Fox Movietone Follies of 1929. Grandeur was a forerunner of the Todd-AO 70mm system which was introduced in 1955, Grandeur was one of a number of wide screen processes which were developed by the major Hollywood studios alongside sound in the late 1920s and early 1930s. A combination of the Great Depression and the costs of converting thousands of cinemas to sound prevented the introduction of any of these projection systems on a commercial scale. The scene of the train drive across the country was pioneering in its use of camera work. An effort was made to lend authenticity to the movie, with the wagons drawn by oxen instead of horses - they were lowered by ropes down canyons when necessary for certain shots in narrow valleys. Tyrone Power, Sr. s characters clothing looks realistically grimy, locations in five states, starting from New Mexico to California, were used to film the caravans 2, 000-mile trek. According to the Nov.12,1930 issue of the Idaho Falls Post, the change, as stated, was made in response to the requests from nearby residents of Jackson, WY, where the bulk of the movie was filmed. After shooting, the film was previewed to select audiences and generally released on October 1930 and it would be almost 20 years before the concept of widescreen films would be put back into general production. After completion of the film, Wayne found stardom only in low-budget serials and features, it would take nine years, the printer copied at a speed of one frame a second, leading to the films year-long process in preserving its original look

Shane (film)
–
Shane is a 1953 American Technicolor Western film from Paramount, noted for its landscape cinematography, editing, performances, and contributions to the genre. The picture was produced and directed by George Stevens from a screenplay by A. B, Guthrie, Jr. based on the 1949 novel of the same name by Jack Schaefer. Its Oscar-winning cinematography was by Loyal Griggs, Shane stars Alan Ladd, Jean Arthur and Van Heflin, and features Brandon deWilde, Jack Palance, Emile Meyer, Elisha Cook, Jr. and Ben Johnson. Shane was listed No.45 in the 2007 edition of AFIs 100 Years.100 Movies list, Shane, a skilled, laconic gunfighter with a mysterious past, rides into an isolated valley in the sparsely settled state of Wyoming, some time after the Civil War. At dinner with local rancher Joe Starrett and his wife Marian, though they have claimed their land legally under the Homestead Acts, a ruthless cattle baron, Rufus Ryker, has hired rogues and henchmen to harass them and drive them out of the valley. Starrett offers Shane a job, and he accepts, at the towns general store, Shane and other homesteaders are loading up supplies. Shane enters the adjacent to the store, where Rykers men are drinking. Chris Calloway, one of Rykers men, throws a shot of whiskey on Shanes shirt, Shane doesnt rise to the bait, and leaves to the taunts of Rykers men. On the next trip to town, Shane returns the empty soda bottle to the saloon, Shane orders two shots of whiskey, pours one on Calloways shirt and throws the other in his face, then knocks him to the ground. A brawl ensues, Shane prevails, with Starretts help, Ryker declares that the next time they meet, the air will be filled with gun smoke. Joey is drawn to Shane, and to his gun, Shane shows him how to wear a holster and demonstrates his shooting skills, but Marian interrupts the lesson. Guns, she says, are not going to be a part of her sons life, Shane counters that a gun is a tool, no better nor worse than a hoe or axe, and as good or bad as the man using it. Marian retorts that the valley would be better off without any guns—including Shanes, Jack Wilson, an unscrupulous gunfighter working for Ryker, deliberately provokes Frank Stonewall Torrey, a hot-tempered ex-Confederate homesteader. Them rebs are all Southern trash, Wilson says, youre a low-down, lyin Yankee, responds Torrey. Prove it, Wilson replies—and when the farmer goes for his gun. At Torreys funeral, there is talk among the settlers of giving in to Ryker and moving on, Ryker invites Starrett to a meeting at the saloon to negotiate a settlement—and then orders Wilson to kill him when he arrives. Calloway, unable to tolerate Rykers treachery any longer, warns Shane of the double-cross, Starrett says no matter, he will shoot it out with Wilson, and asks Shane to look after Marian and Joey if he dies. Shane, aware that Starrett is no match for Wilson in a gunfight, Starrett is adamant, and Shane is forced to knock him unconscious

Land of the Lost (1974 TV series)
–
Land of the Lost is a childrens adventure television series created by David Gerrold and produced by Sid and Marty Krofft, who co-developed the series with Allan Foshko. During its original run, it was broadcast on the NBC television network and it later aired in daily syndication in the early 1980s as part of the Krofft Superstars package. In 1985, it returned to late Saturday mornings on CBS as a replacement for the canceled Pryors Place - also a Krofft production and it was later shown in reruns on the Sci Fi Channel in the 1990s. Reruns of this series were aired on Saturday mornings on Me-TV but are streamed online at any time on their website and it has since become a cult classic and is now available on DVD. Krofft Productions remade the series in 1991, also titled Land of the Lost, an article on renewed studio interest in feature film versions of Land of the Lost and H. R. C. Fontana, Walter Koenig, and David Gerrold, Gerrold, Niven, and Fontana also contributed commentaries to the DVD of the first season. The prolific Krofft team was influential in childrens television, producing many oddly formatted, highly energetic, the Marshalls are brought to the mysterious world by means of a dimensional portal, a device used frequently throughout the series and a major part of its internal mythology. This portal opens when they are swept down a gigantic 1, outfitted only for a short camping trip, the resourceful family from California takes shelter in a natural cave and improvises the provisions and tools that they need to survive. Their most common and dangerous encounters are with dinosaurs, particularly a Tyrannosaurus rex they nickname Grumpy who frequents the location of their cave, however, many of the dinosaurs are herbivores, posing no threat to the Marshalls, unless unintentionally provoked. One is a particularly tame young Brontosaurus whom Holly nicknames Dopey, and they also encounter the mostly hostile Sleestak, and the primate-like creatures called Pakuni, as well as a variety of dangerous creatures, strange geography and unfamiliar technology. The main goal of the three is to find a way to return home and they are occasionally aided in this by the Altrusian castaway Enik. At the start of the season it is explained that Rick Marshall has been accidentally returned to Earth alone. Rick is immediately replaced by his brother Jack, Rick Marshall abruptly disappeared while trying to use one of the pylons to get home, Jack stumbled upon his niece and nephew after he embarked on a search of his own to find them. Though the term time doorway is used throughout the series, Land of the Lost is not meant to portray an era in Earths history, but rather an enigmatic zone whose place and time are unknown. Indeed, within the first few minutes of the pilot, the Marshall family father tells his children that he spotted three moons in the sky. The original creators of these portals were thought to be the ancestors of the Sleestak, called Altrusians. Uncontrolled time doorways result in the arrival of a variety of visitors, the series intention was to create a realistic fantasy world, albeit relying heavily on childrens acceptance of minor inconsistencies. It was a departure from the Krofft teams previous work

List of mountain ranges in Wyoming
–
According to the United States Board on Geographic Names, there are at least 109 named mountain ranges and sub-ranges in Wyoming. Wyoming /waɪˈoʊmɪŋ/ is a state in the region of the Western United States. Wyoming is the 10th most extensive, but the least populous, the mountain ranges below are listed by name, county, coordinates, and average elevation as recorded by the U. S. Geological Survey. Sub-ranges are indented below the name of the primary range, some of these ranges extend into Colorado, Montana, Idaho, and Utah

U.S. National Geodetic Survey

United States Coast Survey and United States Coast and Geodetic Survey redirect here. Since its foundation in its present form in 1970, it has been part of the National Oceanic and Atmospheric Administration, the National Geodetic Surveys history and heritage are intertwined with those of other NOAA offices. As the U. S. Coast Survey and U. S, upon the creation of the Environmental Science Services Administration in 1965, the commissioned corps was separated from the Survey to become the Environmental Science Services Administration Corps. Thus, the National Geodetic Surveys ancestor organizations are also the ancestors of todays NOAA Corps, in addition, todays National Institute of Standards and Technology, although long since separated from the Survey, got its start as the Surveys Office of Weights and Measures. The National Geodetic Survey is an office of NOAAs National Ocean Service, NGS is responsible for defining the NSRS and its relationship with the International Terrestrial Reference Frame. The NSRS enables precise and accessible knowledge of things are in the United States. The NSRS may be divided into its geometric and physical components, the official geodetic datum of the United States, NAD83 defines the geometric relationship between points within the United States in three-dimensional space. The datum may be accessed via NGSs network of marks or through the Continuously Operating Reference Station network of GPS reference antennas. NGS is responsible for computing the relationship between NAD83 and the ITRF, the physical components of the NSRS are reflected in its height system, defined by the vertical datum NAVD88. This datum is a network of orthometric heights obtained through spirit leveling, NGS will release new datums in 2022. The North American Terrestrial Reference Frame of 2022 will supersede NAD83 in defining the relationship between the North American plate and the ITRF. United States territories on the Pacific, Caribbean, and Mariana plates will have their own respective geodetic datums, the North American-Pacific Geopotential Datum of 2022 will separately define the height system of the United States and its territories, replacing NAVD88. It will use a geoid model accurate to 1 centimeter to relate orthometric height to ellipsoidal height measured by GPS, NGS provides a number of other public services. The Online Positioning and User Service processes user-input GPS data and outputs position solutions within the NSRS, the agency offers other tools for conversion between datums. A Swiss immigrant with expertise in surveying and the standardization of weights and measures, Ferdinand R. Hassler, was selected to lead the Survey. Hassler departed on August 29,1811, but eight months later, while he was in England, Hassler did not return to the United States until August 16,1815. The Survey finally began surveying operations in 1816, when Hassler started work in the vicinity of New York City, the first baseline was measured and verified in 1817. S. S. Army and U. S. Navy responsibility for coastal surveys, Hassler was reappointed as the Surveys superintendent that year

Wikimedia Commons is an online repository of free-use images, sound, and other media files. It is a project of the Wikimedia Foundation, the repository contains over 38 million media files. In July 2013, the number of edits on Commons reached 100,000,000, the project was proposed by Erik Möller in March 2004 and launched on September 7,2004. The expression educational is to be according to its broad meaning of providing knowledge. Wikimedia Commons itself does not allow fair use or uploads under non-free licenses, for this reason, Wikimedia Commons always hosts freely licensed media and deletes copyright violations. The default language for Commons is English, but registered users can customize their interface to use any other user interface translations. Many content pages, in particular policy pages and portals, have also translated into various languages. Files on Wikimedia Commons are categorized using MediaWikis category system, in addition, they are often collected on individual topical gallery pages. While the project was proposed to also contain free text files. In 2012, BuzzFeed described Wikimedia Commons as littered with dicks, in 2010, Wikipedia co-founder Larry Sanger reported Wikimedia Commons to the FBI for hosting sexualized images of children known as lolicon. Wales responded to the backlash from the Commons community by voluntarily relinquishing some site privileges, over time, additional functionality has been developed to interface Wikimedia Commons with the other Wikimedia projects. Specialized uploading tools and scripts such as Commonist have been created to simplify the process of uploading large numbers of files. In order to free content photos uploaded to Flickr, users can participate in a defunct collaborative external review process. The site has three mechanisms for recognizing quality works, one is known as Featured pictures, where works are nominated and other community members vote to accept or reject the nomination. This process began in November 2004, another process known as Quality images began in June 2006, and has a simpler nomination process comparable to Featured pictures. Quality images only accepts works created by Wikimedia users, whereas Featured pictures additionally accepts nominations of works by third parties such as NASA, the three mentioned processes select a slight part from the total number of files. However, Commons collects files of all quality levels, from the most professional level across simple documental, files with specific defects can be tagged for improvement and warning or even proposed for deletion but there exists no process of systematic rating of all files. The site held its inaugural Picture of the Year competition, for 2006, all images that were made a Featured picture during 2006 were eligible, and voted on by eligible Wikimedia users during two rounds of voting

Absaroka Range
–
The Absaroka Range (/əbˈsɔərkə/ or local /əbˈsɔərki/ is a sub-range of the Rocky Mountains in the United States. The range borders the Beartooth Mountains to the north and the Wind River Range to the south, the northern edge of the range rests along I-90 and Livingston, Montana. The highest peak in the range is Francs Peak, located in Wyoming at 13,153 ft, there are 46 other peaks over 12,000 ft. The range is drained by the Yellowstone River and various tributaries and it is only open during the summer. U. S Route 14/16/20 follows the Shoshone River from Cody through the range to the gate of the park. The range is named after the Absaroka Indians, the name is derived from the Hidatsa name for the Crow people, it means children of the large-beaked bird. John Colter, who may have been the first white person to visit the area, early explorers also included Gustavus Cheyney Doane and Nathaniel P. Langford, who climbed the summit of Colter Peak in 1870. USS Absaroka was named after this mountain range, geologically, the section of the range in Wyoming consists of volcanic breccia, whereas there is a transition to granite and gneiss bedrock further north of the state line. Igneous rocks of the Absaroka Volcanic Province cover an area of approximately 23,000 km2 in southwestern Montana and these extrusive rocks were erupted during the Eocene Epoch of the Paleogene Period. Radiometric dating has shown that eruptive activity lasted from about 53 to 43.7 million years ago, the eroded remnants of many large stratovolcanoes are found in the area. The dissection of these long extinct volcanoes by erosion allows geologists to see structures that are impossible to see in active volcanoes. Many terms now used in volcanology originated in nineteenth century field studies of these ancient volcanoes.

Barronette Peak el.10,354 feet is a mountain peak in the northeast section of Yellowstone National Park in the Absaroka Range. The peak is named for Collins Jack Baronette and it was named by the Hayden Geological Survey of 1878. When named, the name was misspelled Barronette and it retains the official misspelled name today, Jack Baronette was an early Yellowstone guide and entrepreneur. He built and operated the first bridge across the Yellowstone River near the confluence of the Lamar River in 1871 to service miners traveling to Cooke City, in 1870, as a resident of Helena, Montana he participated in the search for and rescue of Truman C. Everts, lost during the Washburn–Langford–Doane Expedition of 1870, in 1884, he was considered for the superintendency of Yellowstone. Mountains and mountain ranges of Yellowstone National Park

Colter Peak el.10,640 feet is a mountain peak in the Absaroka Range in the southeastern section of Yellowstone National Park. The peak is named for mountain man John Colter, reputedly the first white man to visit the Yellowstone region, Colter Peak was first ascended in 1870 by Lt. Gustavus Cheyney Doane and Nathaniel P. Langford during the Washburn–Langford–Doane Expedition. Henry D. Washburn, the expedition named the peak for Langford. For unknown reasons, geologist Ferdinand V. Hayden moved those names to peaks farther north in 1871 during the Hayden Geological Survey of 1871, in 1888, Philetus Norris the second park superintendent, named the peak Mount Forum for unknown reasons. In 1885, geologist Arnold Hague gave the peak its official name, the first detailed map of Yellowstone Lake was sketched by Langford from this peak on September 7,1870.
