Vinson Massif
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 Plateau
Vinson Plateau is the summit plateau of Vinson Massif, Sentinel Range in Ellsworth Mountains, Antarctica. It extends for 9 km between Goodge Col and Hammer Col linking it to the north-central part of Sentinel Range to the north-northwest and to Craddock Massif to the south-southeast respectively, and 4.5 km wide between Branscomb Peak and Silverstein Peak to the west and Schoening Peak and Marts Peak to the east. Elevation from 4000 m to 4600 m above sea level. Rising from the plateau is the summit of Antarctica Mount Vinson (4892 m), and several other peaks higher than 4700 m, albeit of modest prominence: Clinch Peak (4841 m), Corbet Peak (4822 m), Silverstein Peak (4790 m), Schoening Peak (4743 m) and Hollister Peak (4729 m). The lower peaks of Fukushima (4634 m) and Opalchenie (4500 m) stand at the south extremity of the plateau. Its central part is drained by Roché Glacier and a tributary glacier in Jacobsen Valley, with both of them joining Branscomb Glacier. ...

Antarctic Exploration
The history of Antarctica emerges from early Western theories of a vast continent, known as Terra Australis, believed to exist in the far south of the globe. The term ''Antarctic'', referring to the opposite of the Arctic Circle, was coined by Marinus of Tyre in the 2nd century AD. The rounding of the Cape of Good Hope and Cape Horn in the 15th and 16th centuries proved that ''Terra Australis Incognita'' ("Unknown Southern Land"), if it existed, was a continent in its own right. In 1773, James Cook and his crew crossed the Antarctic Circle for the first time; however, although they discovered nearby islands, they did not catch sight of Antarctica itself. It is believed he was as close as from the mainland. On 27 January 1820, a Russian expedition led by Fabian Gottlieb von Bellingshausen and Mikhail Lazarev discovered an ice shelf at Princess Martha Coast that later became known as the Fimbul Ice Shelf. Bellingshausen and Lazarev became the first explorers to see and official ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mount Rutford
Mount Rutford is a sharp peak that rises to and marks the highest point on Craddock Massif in the Sentinel Range, Ellsworth Mountains. The peak stands just north of Bugueño Pinnacle and 2.1 mi north of Mount Craddock, with which this naming is associated. Prior to 2006 the peak had no name, but was visually identified by Camilo Rada and Damien Gildea as being higher than Mt Craddock, during their time on the summits of both Vinson (2004) and Craddock (2005). Thus they returned in 2006 and, as part of a larger GPS program, measured the height of this unnamed peak. As a result of the new GPS data and a new 1:100,000 topographical map being produced by the Omega Foundation, the peak was then named in 2006 by US-ACAN after Robert Hoxie Rutford, member of J. Campbell Craddock's University of Minnesota The University of Minnesota, formally the University of Minnesota, Twin Cities, (UMN Twin Cities, the U of M, or Minnesota) is a public university, public Land-grant univ ...

Craddock Massif
Craddock Massif is a mountain massif in the Sentinel Range of the Ellsworth Mountains, in the Chilean claim of West Antarctica. Location and highest point Craddock Massif is located at the southeastern side of Vinson Massif, between Hammer Col and Karnare Col linking it to Vinson Massif and the southern Sentinel Range respectively. The highest point of Craddock Massif is Mount Rutford, a sharp peak that rises to . The Craddock Massif also includes (from north to south) Bugueño Pinnacle, Rada Peak and Mount Craddock. Discovery and naming Sentinel Range was first sighted and photographed from the air on November 23, 1935, by Lincoln Ellsworth. The entire range, including Craddock Massif, was mapped by the United States Geological Survey from aerial photography taken by the U.S. Navy, 1958–61. This massif was originally named "Mount Craddock" by the Advisory Committee on Antarctic Names (US-ACAN) in 1965, but subsequent maps limited the name to the massif's southernmo ...

Hammer Col
Hammer Col is a broad ice-covered col at elevation between the south part of the Vinson Massif and the Craddock Massif in the Sentinel Range of the Ellsworth Mountains, Antarctica. The wide saddle is relatively level and visually separates the two massifs whether viewed from the east or the west. It is part of the glacial divide between the heads of Dater Glacier on the northeast and Gildea Glacier on the southwest. The feature was named by the Advisory Committee on Antarctic Names (2006) after William R. Hammer of the Department of Geology, Augustana College, Rock Island, IL, a U.S. Antarctic Program investigator of vertebrate fossils, primarily in the central Transantarctic Mountains The Transantarctic Mountains (abbreviated TAM) comprise a mountain range of uplifted (primarily sedimentary) rock in Antarctica which extend, with some interruptions, across the continent from Cape Adare in northern Victoria Land to Coats Land. ..., 1977–2003.

Dater Glacier
The Dater Glacier is a steep valley glacier in Antarctica, long and from wide, flowing northeast in a sinuous course from the eastern slopes of the Vinson Massif between Sullivan Heights and Veregava Ridge to Rutford Ice Stream which borders the eastern flank of the Sentinel Range, Ellsworth Mountains. At the lower end the Dater Glacier coalesces with the terminus of the Ellen Glacier, the two emerging from the Sentinel Range as one stream just north of the Flowers Hills. The glacier was discovered by U.S. Navy Squadron VX-6 on photographic flights of December 14–15, 1959, and mapped from these photographs by the United States Geological Survey. It was named by the Advisory Committee on Antarctic Names after Henry M. Dater, a historian on the staff of the U.S. Antarctic Projects Officer and the U.S. Naval Support Force Antarctica.

Gildea Glacier
Gildea Glacier is a glacier long and wide flowing southwestward from Craddock Massif between Mount Slaughter and Mount Atkinson into Nimitz Glacier, in the Sentinel Range of the Ellsworth Mountains, Antarctica. The upper portion of the glacier also receives ice from Hammer Col and southern Vinson Massif. It was named by the Advisory Committee on Antarctic Names in 2006 after Damien Gildea, the Australian leader of several Omega Foundation expeditions to the Sentinel Range and Livingston Island in 2000–07. He made an ascent of Mount Craddock from the Bender Glacier in 2005, and directed the preparation of a 1:50,000-scale map of the Vinson Massif area for publication by the Omega Foundation in 2006.
