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 The South Pole, also known as the Geographic South Pole or Terrestrial South Pole, is the point in the Southern Hemisphere where the Earth's rotation, Earth's axis of rotation meets its surface.

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 became 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, the three highest peaks of every continent. Because of glacial melting and the disagreement over exactly which three peaks are the tallest in the Australia (continent), Australian continent, Stangl also climbed several additional candidate peaks including Sumantri (), Ngga Pulu (), and Mount Twynam(). 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 ...

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 United States Air Force Colonel Horace A. Crosswell, 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 or Terrestrial South Pole, is the point in the Southern Hemisphere where the Earth's rotation, Earth's axis of rotation meets its surface. It is called the True South Pole to distinguish from the south magnetic pole. The South Pole is by definition the southernmost point on the Earth, lying antipode (geography), antipodally to the North Pole. It defines geodetic latitude 90° South, as well as the direction of true south. At the South Pole all directions point North; all lines of longitude converge there, so its longitude can be defined as any degree value. No time zone has been assigned to the South Pole, so any time can be used as the local time. Along tight latitude circles, clockwise is east and counterclockwise is west. The South Pole is at the center of the Southern Hemisphere. Situated on the continent of Antarctica, it is the site of the United States Amundsen–Scott South Pole Station, which was established in 19 ...

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; ), also referred to as the third International Polar Year, 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 China, 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 fourteen Earth science disciplines: Auroral light, aurora, airglow, cosmic rays, Earth's magnetic field, geomagnetism, gravity, ionosphere, ionospheric physics, longitude and latitude determinations (precision mapping), meteorology, oceanography, Ionizing radiation, nuclear radiation, glaciology, seismo ...

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. Branscomb Glacier has been the focus of scientific research expeditions aimed at studying glaciology, ice dynamics, and climate change in Antarctica. 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.

Mount Tyree
Mount Tyree (4852m) is the second highest mountain of Antarctica located 13 kilometres northwest of Mount Vinson (4,892 m), the highest peak on the continent. It surmounts Patton Glacier to the north and Cervellati Glacier to the southeast. History Mt. Tyree was discovered in January 1958 during reconnaissance flights by the United States Navy VX-6 squadron, and mapped later that month by the Marie Byrd Land Traverse Party. The mountain was named for Rear Admiral David M. Tyree, who was commander of the U.S. Naval Support Force in Antarctica, from April 14, 1959 to November 26, 1962. As of 2017, the summit had only been reached on six occasions, by a total of fifteen people, via three different routes: in January 1967 by John Evans and Barry Corbet (of Corbet's Couloir Corbet's Couloir is an expert ski run located at the Jackson Hole Mountain Resort in Teton Village, Wyoming.

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 area, and is usually higher than a hill, typically rising at least above the surrounding land. A few mountains are inselberg, 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, ecosystems of mountains: different elevations hav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
