Amphitheater Mountain (Wyoming)
Amphitheater Mountain is a prominent mountain summit located in Park County, Wyoming, United States. Description The peak is situated southwest of the town of Cooke City, Montana, at the northeast corner of Yellowstone National Park, two miles south of the park's Northeast Entrance Station. It is part of the Absaroka Range, and a portion of the mountain is within the North Absaroka Wilderness. Topographic relief is significant as the north aspect rises over above Silver Gate in two miles. Volcanoes of the early Eocene supplied the material that formed the mountain 50–55 million years ago, and here created some of the most rugged terrain in Yellowstone Park.Mary Meagher, Douglas B. Houston, ''Yellowstone and the Biology of Time'', 1999, University of Oklahoma Press, , page 142. The mountain's name has been officially adopted by the United States Board on Geographic Names. Climate According to the Köppen climate classification system, Amphitheater Mountain is located in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pilot Peak (Wyoming)
Pilot Peak, elevation , is a prominent mountain peak in the Absaroka Range in Park County, Wyoming. The peak is visible from US Route 212, the Beartooth Highway just east of the Northeast Entrance Station to Yellowstone National Park. Index Peak rises just north of Pilot Peak. Pilot Peak is composed of crumbly rock and rarely climbed. Its first documented ascent was in 1932 by Robert McKenzie and Hollis Mees. Pilot Peak's name first appeared on an 1873 map, and was officially adopted in 1937 by the United States Board on Geographic Names. Climate According to the Köppen climate classification system, Pilot Peak is located in a subarctic climate zone with long, cold, snowy winters, and cool to warm summers. Temperatures can drop below −10 °F with wind chill factors below −30 °F. Precipitation runoff from the mountain drains into tributaries of the Clarks Fork Yellowstone River.

Eocene
The Eocene ( ) Epoch is a geological epoch that lasted from about 56 to 33.9 million years ago (mya). It is the second epoch of the Paleogene Period in the modern Cenozoic Era. The name ''Eocene'' comes from the Ancient Greek (''ēṓs'', " dawn") and (''kainós'', "new") and refers to the "dawn" of modern ('new') fauna that appeared during the epoch. The Eocene spans the time from the end of the Paleocene Epoch to the beginning of the Oligocene Epoch. The start of the Eocene is marked by a brief period in which the concentration of the carbon isotope 13C in the atmosphere was exceptionally low in comparison with the more common isotope 12C. The end is set at a major extinction event called the ''Grande Coupure'' (the "Great Break" in continuity) or the Eocene–Oligocene extinction event, which may be related to the impact of one or more large bolides in Siberia and in what is now Chesapeake Bay. As with other geologic periods, the strata that define the start and e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North American 3000 M Summits
North is one of the four compass points or cardinal directions. It is the opposite of south and is perpendicular to east and west. ''North'' is a noun, adjective, or adverb indicating Direction (geometry), direction or geography. Etymology The word ''north'' is etymology, related to the Old High German ''nord'', both descending from the Proto-Indo-European language, Proto-Indo-European unit *''ner-'', meaning "left; below" as north is to left when facing the rising sun. Similarly, the other cardinal directions are also related to the sun's position. The Latin word ''borealis'' comes from the Ancient Greek, Greek ''Anemoi#Boreas, boreas'' "north wind, north", which, according to Ovid, was personified as the wind-god Anemoi#Boreas, Boreas, the father of Calais and Zetes. ''Septentrionalis'' is from ''septentriones'', "the seven plow oxen", a name of ''Ursa Major''. The Greek ἀρκτικός (''arktikós'') is named for the same constellation, and is the source of the English ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mountains Of Wyoming
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain and ...

Lamar River
The Lamar River is a tributary of the Yellowstone River, approximately long, in northwestern Wyoming in the United States. The river is located entirely within Yellowstone National Park. History Prior to the 1884–85 Geological Survey of the park, the Lamar was known as the East Fork of the Yellowstone River. During that survey, Geologist Arnold Hague named the river for L.Q.C. (Lucius Quintius Cincinnatus) Lamar, then Secretary of the Interior (March 1885 – January 1888), and a former slaveholder and author of the Mississippi Ordinance of Secession. The Lamar Valley, or the ''Secluded Valley'' of Trapper Osborne Russell and other park features or administrative names which contain ''Lamar'' are derived from this original naming. Osborne Russell in his 1921 ''Journal of a Trapper'' described the Lamar as follows: In 1869, the Cook–Folsom–Peterson Expedition encountered the Lamar River (East Fork) just upstream from the canyon section flowing into the Yellowsto ...

Surface Runoff
Surface runoff (also known as overland flow) is the flow of water occurring on the ground surface when excess rainwater, stormwater, meltwater, or other sources, can no longer sufficiently rapidly infiltrate in the soil. This can occur when the soil is saturated by water to its full capacity, and the rain arrives more quickly than the soil can absorb it. Surface runoff often occurs because impervious areas (such as roofs and pavement) do not allow water to soak into the ground. Furthermore, runoff can occur either through natural or man-made processes. Surface runoff is a major component of the water cycle. It is the primary agent of soil erosion by water. The land area producing runoff that drains to a common point is called a drainage basin. Runoff that occurs on the ground surface before reaching a channel can be a nonpoint source of pollution, as it can carry man-made contaminants or natural forms of pollution (such as rotting leaves). Man-made contaminants in runoff i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subarctic Climate
The subarctic climate (also called subpolar climate, or boreal climate) is a climate with long, cold (often very cold) winters, and short, warm to cool summers. It is found on large landmasses, often away from the moderating effects of an ocean, generally at latitudes from 50° to 70°N, poleward of the humid continental climates. Subarctic or boreal climates are the source regions for the cold air that affects temperate latitudes to the south in winter. These climates represent Köppen climate classification ''Dfc'', ''Dwc'', ''Dsc'', ''Dfd'', ''Dwd'' and ''Dsd''. Description This type of climate offers some of the most extreme seasonal temperature variations found on the planet: in winter, temperatures can drop to below and in summer, the temperature may exceed . However, the summers are short; no more than three months of the year (but at least one month) must have a 24-hour average temperature of at least to fall into this category of climate, and the coldest month should a ...

Köppen Climate Classification
The Köppen climate classification is one of the most widely used climate classification systems. It was first published by German-Russian climatologist Wladimir Köppen (1846–1940) in 1884, with several later modifications by Köppen, notably in 1918 and 1936. Later, the climatologist Rudolf Geiger (1894–1981) introduced some changes to the classification system, which is thus sometimes called the Köppen–Geiger climate classification system. The Köppen climate classification divides climates into five main climate groups, with each group being divided based on seasonal precipitation and temperature patterns. The five main groups are ''A'' (tropical), ''B'' (arid), ''C'' (temperate), ''D'' (continental), and ''E'' (polar). Each group and subgroup is represented by a letter. All climates are assigned a main group (the first letter). All climates except for those in the ''E'' group are assigned a seasonal precipitation subgroup (the second letter). For example, ''Af'' i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Board On Geographic Names
The United States Board on Geographic Names (BGN) is a federal body operating under the United States Secretary of the Interior. The purpose of the board is to establish and maintain uniform usage of geographic names throughout the federal government of the United States. History On January 8, 1890, Thomas Corwin Mendenhall, superintendent of the US Coast and Geodetic Survey Office, wrote to 10 noted geographers "to suggest the organization of a Board made up of representatives from the different Government services interested, to which may be referred any disputed question of geographical orthography." President Benjamin Harrison signed executive order 28 on September 4, 1890, establishing the ''Board on Geographical Names''. "To this Board shall be referred all unsettled questions concerning geographic names. The decisions of the Board are to be accepted y federal departmentsas the standard authority for such matters." The board was given authority to resolve all unsettled q ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
