Taylor Ledge
Taylor Ledge is a notable flat-topped ridge displaying abrupt cliffs north and south, situated between Boyce Ridge and Mount Shinn on the west slope of Sentinel Range, Ellsworth Mountains in Antarctica. The upper surface of the feature is ice covered and relatively level except for 3373-meter Knutzen Peak on the north edge. The ridge was named by the Advisory Committee on Antarctic Names (US-ACAN) in 2006 after Thomas N. and Edith L. Taylor, Department of Ecology and Evolutionary Biology, University of Kansas, Lawrence, husband and wife U.S. Antarctic Project (USAP) researchers of plant fossils in the central Transantarctic Mountains, 1980s–2004.

Boyce Ridge
Boyce Ridge is a 4.4-mile (7-km) ridge that extends westward from Taylor Ledge to the head of Nimitz Glacier in Sentinel Range, Ellsworth Mountains in Antarctica. The ridge adjoins the north flank of lower Branscomb Glacier. The feature was named by the Advisory Committee on Antarctic Names (US-ACAN) in 2006 after Joseph Boyce, a retired NASA manager who was instrumental in facilitating the U.S. meteorite program in partnership with NSF and the Smithsonian Institution; a member of the ANSMET ANSMET (Antarctic Search for Meteorites) is a program funded by the Office of Polar Programs of the National Science Foundation that looks for meteorites in the Transantarctic Mountains.

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 ...

Sentinel Range
The Sentinel Range is a major mountain range situated northward of Minnesota Glacier and forming the northern half of the Ellsworth Mountains in Antarctica. The range trends NNW-SSE for about and is 24 to 48 km (15 to 30 mi) wide. Many peaks rise over and Vinson Massif (4892 m) in the southern part of the range is the highest elevation on the continent.Sentinel Range. SCAR Composite Antarctic Gazetteer. Sentinel Range comprises a main ridge (featuring Vinson Massif in its southern portion) and a number of distinct heights, ridges and mountains on its east side, including (south to north) , [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ellsworth Mountains
The Ellsworth Mountains are the highest mountain ranges in Antarctica, forming a long and wide chain of mountains in a north to south configuration on the western margin of the Ronne Ice Shelf in Marie Byrd Land. They are bisected by Minnesota Glacier to form the Sentinel Range to the north and the Heritage Range to the south. The former is by far the higher and more spectacular with Mount Vinson () constituting the highest point on the continent.Bockheim, J.G., Schaefer, C.E., 2015. ''Soils of Ellsworth Land, the Ellsworth Mountains''. In: Bockheim, J.G. (Ed.), ''The Soils of Antarctica. World Soils Book Series'', Springer, Switzerland, pp. 169–181. The mountains are located within the Chilean Antarctic territorial claim but outside of the Argentinian and British ones. Discovery The mountains were discovered on November 23, 1935, by Lincoln Ellsworth in the course of a trans-Antarctic flight from Dundee Island to the Ross Ice Shelf. He gave them the descriptive name Sentinel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antarctica
Antarctica () is Earth's southernmost and least-populated continent. Situated almost entirely south of the Antarctic Circle and surrounded by the Southern Ocean, it contains the geographic South Pole. Antarctica is the fifth-largest continent, being about 40% larger than Europe, and has an area of . Most of Antarctica is covered by the Antarctic ice sheet, with an average thickness of . Antarctica is, on average, the coldest, driest, and windiest of the continents, and it has the highest average elevation. It is mainly a polar desert, with annual precipitation of over along the coast and far less inland. About 70% of the world's freshwater reserves are frozen in Antarctica, which, if melted, would raise global sea levels by almost . Antarctica holds the record for the lowest measured temperature on Earth, . The coastal regions can reach temperatures over in summer. Native species of animals include mites, nematodes, penguins, seals and tardigrades. Where vegetation o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Knutzen Peak
Knutzen Peak is a sharp, rocky summit of elevation standing on the north edge of Taylor Ledge in the Sentinel Range of the Ellsworth Mountains, Antarctica. It surmounts Branscomb Glacier to the east and south. The peak was named by US-ACAN in 2006 after Donald H. Knutzen, topographic engineer with the U.S. Geological Survey in the Sentinel Range, 1979–80. Location Knutzen Peak is located at , which is southwest of Mount Shinn, west-northwest of Branscomb Peak and north of Brichebor Peak. US mapping in 1961, updated in 1988.

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] |
Transantarctic Mountains
The Transantarctic Mountains (abbreviated TAM) comprise a mountain range of uplifted (primarily sedimentary rock, sedimentary) rock in Antarctica which extend, with some interruptions, across the continent from Cape Adare in northern Victoria Land to Coats Land. These mountains divide East Antarctica and West Antarctica. They include a number of separately named mountain groups, which are often again subdivided into smaller ranges. The range was first sighted by James Clark Ross in 1841 at what was later named the Ross Ice Shelf in his honour. It was first crossed during the British National Antarctic Expedition of 1901-1904. Geography The mountain range stretches between the Ross Sea and the Weddell Sea, the entire width of Antarctica, hence the name. With a total length of about , the Transantarctic Mountains are one of the longest mountain ranges on Earth. The Antarctandes are even longer, having in common with the Transantarctic Mountains the ranges from Cape Adare to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mount Vinson
Vinson Massif () is a large mountain massif in Antarctica that is long and wide and lies within the Sentinel Range of the Ellsworth Mountains. It overlooks the Ronne Ice Shelf near the base of the Antarctic Peninsula. The massif is located about from the South Pole. Vinson Massif was discovered in January 1958 by U.S. Navy aircraft. In 1961, the Vinson Massif was named by the Advisory Committee on Antarctic Names (US-ACAN), after Carl G. Vinson, United States congressman from the state of Georgia, for his support for Antarctic exploration. On November 1, 2006, US-ACAN declared Mount Vinson and Vinson Massif to be separate entities.Stewart, J. (2011) ''Antarctic An Encyclopedia'' McFarland & Company Inc, New York. 1776 pp. . Vinson Massif lies within the Chilean claim under the Antarctic Treaty System. Mount Vinson is the highest peak in Antarctica, at . It lies in the north part of Vinson Massif's summit plateau in the south portion of the main ridge of the Sentinel Range ...
