Mount Shinn
Mount Shinn is a mountain 4,661 meters in elevation, standing 6 km (4 miles) southeast of Mount Tyree in the Sentinel Range, Ellsworth Mountains in Antarctica. It surmounts Ramorino Glacier to the north, upper Crosswell Glacier to the northeast, Goodge Col to the southeast, and Branscomb Glacier to the south-southwest. Mount Shinn is thought to be the third-highest peak in Antarctica. The peak was discovered on IGY reconnaissance flights in January 1958, and named by the Advisory Committee on Antarctic Names (US-ACAN) for Lieutenant Commander Conrad S. (Gus) Shinn, U.S. Navy, a pilot on some of these flights. Shinn was pilot of the Navy R4D aircraft carrying Admiral Dufek which, on October 31, 1956, made the first plane landing at the geographic South Pole. It had been thought to be over 4800m high, but was re-measured in 2001 by Damien Gildea Damien Gildea (born 1969) is an Australian mountaineer and Antarctic explorer who has climbed extensively in Antarctic ...

Seven Third Summits
The Seven Third Summits are the third-highest mountains of each of the seven continents. All of these mountain peaks are separate peaks rather than a sub-peak of the continents' high point. Christian Stangl from Austria claims to be the first person to reach the summit of all seven ''third summit'' mountains after climbing Puncak Mandala and Puncak Trikora. He did this as a part of his Triple Seven Summits project. Because of glacial melting and the disagreement over exactly which three peaks are the tallest in the Australian continent, Stangl also climbed several additional candidate peaks including Sumantri () and Ngga Pulu (). Definitions The definition of ''continent'' is a matter of some dispute among mountaineers seeking to complete this challenge. The main ridge of the Greater Caucasus range is generally considered to form the boundary between Asia and Europe. In that case, Mount Elbrus () and Dykh-Tau (), are the two highest mountains in Europe. Excluding the Caucasus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crosswell Glacier
Crosswell Glacier () is a glacier long, flowing north-northeast from Mount Shinn between Sullivan Heights and Bearskin Ridge, in the central part of the Sentinel Range, Ellsworth Mountains, Antarctica. Together with Patton and Pulpudeva Glaciers, it enters Ellen Glacier northwest of Mamarchev Peak and southeast of Mount Jumper. The glacier was first mapped by the United States Geological Survey from surveys and from U.S. Navy air photos, 1957–59, and named by the Advisory Committee on Antarctic Names for Colonel Horace A. Crosswell, United States Air Force, leader of C-124 Globemaster air drops in establishing the scientific station at the South Pole in the 1956–57 season.

South Pole
The South Pole, also known as the Geographic South Pole, Terrestrial South Pole or 90th Parallel South, is one of the two points where Earth's axis of rotation intersects its surface. It is the southernmost point on Earth and lies antipodally on the opposite side of Earth from the North Pole, at a distance of 12,430 miles (20,004 km) in all directions. Situated on the continent of Antarctica, it is the site of the United States Amundsen–Scott South Pole Station, which was established in 1956 and has been permanently staffed since that year. The Geographic South Pole is distinct from the South Magnetic Pole, the position of which is defined based on Earth's magnetic field. The South Pole is at the centre of the Southern Hemisphere. Geography For most purposes, the Geographic South Pole is defined as the southern point of the two points where Earth's axis of rotation intersects its surface (the other being the Geographic North Pole). However, Earth's axis of rotat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
International Geophysical Year
The International Geophysical Year (IGY; french: Année géophysique internationale) was an international scientific project that lasted from 1 July 1957 to 31 December 1958. It marked the end of a long period during the Cold War when scientific interchange between East and West had been seriously interrupted. Sixty-seven countries participated in IGY projects, although one notable exception was the mainland People's Republic of China, which was protesting against the participation of the Republic of China (Taiwan). East and West agreed to nominate the Belgian Marcel Nicolet as secretary general of the associated international organization. The IGY encompassed eleven Earth sciences: aurora and airglow, cosmic rays, geomagnetism, gravity, ionospheric physics, longitude and latitude determinations (precision mapping), meteorology, oceanography, seismology, and solar activity. The timing of the IGY was particularly suited for studying some of these phenomena, since it covered th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Branscomb Glacier
The Branscomb Glacier () is an Antarctic glacier, long, flowing west from the north-west side of Vinson Massif (the highest point in Antarctica) into Nimitz Glacier, in the Sentinel Range of the Ellsworth Mountains. Its upper course receives ice influx from both Goodge Col and Jacobsen Valley, while the tributary Roché Glacier joins Branscomb Glacier just northwest of Príncipe de Asturias Peak. The glacier was mapped by the USGS from surveys and USN aerial photographs between 1957 and 1960. It was named by US-ACAN after Lewis M. Branscomb, Chairman of the National Science Board from 1982 to 1984.

Goodge Col
Goodge Col () is a broad ice-covered col at elevation between the south side of Mount Shinn and the Vinson Massif in the Sentinel Range of the Ellsworth Mountains in Antarctica. The col is relatively level, wide, and is easily identified from positions east and west of the range. It drains northeastwards into Crosswell Glacier, eastwards into Hinkley Glacier and, jointly with the ice filled Jacobsen Valley, westwards into Branscomb Glacier. Goodge Col was named by the Advisory Committee on Antarctic Names (2006) after John W. Goodge, Assistant Professor in the Department of Geological Sciences, University of Minnesota, Duluth, and a United States Antarctic Program The United States Antarctic Program (or USAP; formerly known as the United States Antarctic Research Program or USARP and the United States Antarctic Service or USAS) is an organization of the United States government which has presence in the A ... investigator of the evolution of the East Antarctic shield, ...

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 ...
