Mountain
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 (topography), 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 Monadnock, isolated summits, but most occur in mountain ranges. Mountain formation, Mountains are formed through Tectonic plate, 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 Slump (geology), slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce Alpine climate, colder climates than at sea level at similar latitude. These colder climates strongly affect the Montane ecosystems, ecosys ...

Nunatak
A nunatak (from Inuit ''nunataq'') is the summit or ridge of a mountain that protrudes from an ice field or glacier that otherwise covers most of the mountain or ridge. They are also called glacial islands. Examples are natural pyramidal peaks. When rounded by glacial action, smaller rock promontories may be referred to as rognons. The word is of Greenlandic origin and has been used in English since the 1870s. Description The term is typically used in areas where a permanent ice sheet is present and the nunataks protrude above the sheet.J. J. Zeeberg, ''Climate and Glacial History of the Novaya Zemlya Archipelago, Russian Arctic''. pp. 82–84 Nunataks present readily identifiable landmark reference points in glaciers or ice caps and are often named. While some nunataks are isolated, sometimes they form dense clusters, such as Queen Louise Land in Greenland. Nunataks are generally angular and jagged, which hampers the formation of glacial ice on their tops, although snow can a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mount Harry
The FitzGerald Bluffs () are prominent north-facing bluffs, long, located south of the Snow Nunataks in Palmer Land, Antarctica. They were discovered by the Ronne Antarctic Research Expedition (1947–48) under Finn Ronne, who named the bluffs after Gerald FitzGerald, Chief Topographic Engineer with the United States Geological Survey, 1947–57. See also *O'Neill Peak O'Neill Peak () is the highest point (about 850 m) of FitzGerald Bluffs, on the English Coast, Palmer Land.

Palmer Land
Palmer Land () is the portion of the Antarctic Peninsula, Antarctica that lies south of a line joining Cape Jeremy and Cape Agassiz. This application of Palmer Land is consistent with the 1964 agreement between the Advisory Committee on Antarctic Names and the UK Antarctic Place-Names Committee, in which the name Antarctic Peninsula was approved for the major peninsula of Antarctica, and the names Graham Land and Palmer Land for the northern and southern portions, respectively. The line dividing them is roughly 69° S. Boundaries In its southern extreme, the Antarctic Peninsula stretches west, with Palmer Land eventually bordering Ellsworth Land along the 80° W line of longitude. Palmer Land is bounded in the south by the ice-covered Carlson Inlet, an arm of the Filchner-Ronne Ice Shelf, which crosses the 80° W line. This is the base of Cetus Hill. This feature is named after Nathaniel Palmer, an American sealer who explored the Antarctic Peninsula area southward of Deceptio ...

Lincoln Ellsworth
Lincoln Ellsworth (May 12, 1880 – May 26, 1951) was a polar explorer from the United States and a major benefactor of the American Museum of Natural History. Biography Lincoln Ellsworth was born on May 12, 1880, to James Ellsworth and Eva Frances Butler in Chicago, Illinois. He also lived in Hudson, Ohio, as a child. He attended The Hill School and took two years longer than usual to graduate, before entering the Sheffield Scientific School at Yale University. His academic performance was poor, and he subsequently enrolled at Columbia University and McGill before ending his academic career. Lincoln Ellsworth's father, James, a wealthy coal man from the United States, spent US$100,000 to fund Roald Amundsen's 1925 attempt to fly from Svalbard to the North Pole. Amundsen, accompanied by Lincoln Ellsworth, pilot Hjalmar Riiser-Larsen, flight mechanic Karl Feucht and two other team members, set out in two Dornier Wal flying boats, the N24 and N25, in an attempted to reach the ...

United States Geological Survey
The United States Geological Survey (USGS), formerly simply known as the Geological Survey, is a scientific agency of the United States government. The scientists of the USGS study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The organization's work spans the disciplines of biology, geography, geology, and hydrology. The USGS is a fact-finding research organization with no regulatory responsibility. The agency was founded on March 3, 1879. The USGS is a bureau of the United States Department of the Interior; it is that department's sole scientific agency. The USGS employs approximately 8,670 people and is headquartered in Reston, Virginia. The USGS also has major offices near Lakewood, Colorado, at the Denver Federal Center, and Menlo Park, California. The current motto of the USGS, in use since August 1997, is "science for a changing world". The agency's previous slogan, adopted on the occasion of its hundredt ...

Advisory Committee On Antarctic Names
The Advisory Committee on Antarctic Names (ACAN or US-ACAN) is an advisory committee of the United States Board on Geographic Names responsible for recommending commemorative names for features in Antarctica. History The committee was established in 1943 as the Special Committee on Antarctic Names (SCAN). It became the Advisory Committee on Antarctic Names in 1947. Fred G. Alberts was Secretary of the Committee from 1949 to 1980. By 1959, a structured nomenclature was reached, allowing for further exploration, structured mapping of the region and a unique naming system. A 1990 ACAN gazeeter of Antarctica listed 16,000 names. Description The United States does not recognise territorial boundaries within Antarctica, so ACAN assigns names to features anywhere within the continent, in consultation with other national nomenclature bodies where appropriate, as defined by the Antarctic Treaty System. The research and staff support for the ACAN is provided by the United States Geologi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Topographic Engineer
Topography is the study of the forms and features of land surfaces. The topography of an area may refer to the land forms and features themselves, or a description or depiction in maps. Topography is a field of geoscience and planetary science and is concerned with local detail in general, including not only relief, but also natural, artificial, and cultural features such as roads, land boundaries, and buildings. In the United States, topography often means specifically ''relief'', even though the USGS topographic maps record not just elevation contours, but also roads, populated places, structures, land boundaries, and so on. Topography in a narrow sense involves the recording of relief or terrain, the three-dimensional quality of the surface, and the identification of specific landforms; this is also known as geomorphometry. In modern usage, this involves generation of elevation data in digital form (DEM). It is often considered to include the graphic representation of the ...
