Epperly Ridge
Epperly Ridge () is a rock ridge that extends northeast for from Mount Epperly, in the Sentinel Range of the Ellsworth Mountains. It was named by the 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.

Mount Epperly
Mount Epperly is a or perhaps Damien GildeaTwenty-Hour Epperly Push For New Route, GPS Height Alpinist, 2008 mountain in the Sentinel Range, Ellsworth Mountains in Antarctica. It overlooks Cervellati Glacier to the northeast and Ramorino Glacier to the east-northeast. The peak was first climbed by Erhard Loretan, solo over the south face, on December 1, 1994. Loretan returned the next year and reclimbed the route for a film. In 1999, the American climbers Conrad Anker and Jim Donini failed in their attempt over the west ridge. The third successful ascent was by the Chilean Camilo Rada and Australian Damien Gildea via a new route over the south face in December 2007. Their GPS measurements on top suggested a height 153 m above the official one. This mountain is named after Robert Epperly (born 1926) who spent time during the International Geophysical Year of 1957–1958 in Antarctica. Bob served in the US Navy at that time. He lived his latter years in Worthington, Massach ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
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] |
Ridges Of Ellsworth Land
A ridge or a mountain ridge is a geographical feature consisting of a chain of mountains or hills that form a continuous elevated crest for an extended distance. The sides of the ridge slope away from the narrow top on either side. The lines along the crest formed by the highest points, with the terrain dropping down on either side, are called the ridgelines. Ridges are usually termed hills or mountains as well, depending on size. Smaller ridges, especially those leaving a larger ridge, are often referred to as spurs. Types There are several main types of ridges: ;Dendritic ridge: In typical dissected plateau terrain, the stream drainage valleys will leave intervening ridges. These are by far the most common ridges. These ridges usually represent slightly more erosion resistant rock, but not always – they often remain because there were more joints where the valleys formed or other chance occurrences. This type of ridge is generally somewhat random in orientation, often ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
