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 southernmost ...

West Antarctica
West Antarctica, or Lesser Antarctica, one of the two major regions of Antarctica, is the part of that continent that lies within the Western Hemisphere, and includes the Antarctic Peninsula. It is separated from East Antarctica by the Transantarctic Mountains and is covered by the West Antarctic Ice Sheet. It lies between the Ross Sea (partly covered by the Ross Ice Shelf), and the Weddell Sea (largely covered by the Filchner-Ronne Ice Shelf). It may be considered a giant peninsula, stretching from the South Pole towards the tip of South America. West Antarctica is largely covered by the Antarctic ice sheet, but there have been signs that climate change is having some effect and that this ice sheet may have started to shrink slightly. Over the past 50 years, the west coast of the Antarctic Peninsula has been - and still is - one of the most rapidly warming parts of the planet, and the coasts of the Peninsula are the only parts of West Antarctica that become (in summer) ice-free ...

Mountain Ranges Of Ellsworth Land
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 ...

Heritage Range
The Heritage Range is a major mountain range, long and wide, situated southward of Minnesota Glacier and forming the southern half of the Ellsworth Mountains in Antarctica. The range is complex, consisting of scattered ridges and peaks of moderate height, escarpments, hills and nunataks, with the various units of relief set off by numerous intervening glaciers. The northern portion of the range was probably first sighted by Lincoln Ellsworth in the course of his trans-Antarctic flight of November 23, 1935. On December 14, 1959, the southern range was seen for the first time in a reconnaissance flight from Byrd Station, made by Edward C. Thiel, J. C. Craddock and E. S. Robinson. The team landed at a glacier on Pipe Peak, in the northwestern part of the range, on December 26.Gerald F.

Summit (topography)
A summit is a point on a surface that is higher in elevation than all points immediately adjacent to it. The topographic terms acme, apex, peak (mountain peak), and zenith are synonymous. The term (mountain top) is generally used only for a mountain peak that is located at some distance from the nearest point of higher elevation. For example, a big, massive rock next to the main summit of a mountain is not considered a summit. Summits near a higher peak, with some prominence or isolation, but not reaching a certain cutoff value for the quantities, are often considered ''subsummits'' (or ''subpeaks'') of the higher peak, and are considered part of the same mountain. A pyramidal peak is an exaggerated form produced by ice erosion of a mountain top. Summit may also refer to the highest point along a line, trail, or route. The highest summit in the world is Mount Everest with a height of above sea level. The first official ascent was made by Tenzing Norgay and Sir Edmund Hillary ...

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] |

Lincoln Ellsworth
Lincoln Ellsworth (May 12, 1880 – May 26, 1951) was a polar explorer from the United States and a major benefactor of the American Museum of Natural History. Biography Lincoln Ellsworth was born on May 12, 1880, to James Ellsworth and Eva Frances Butler in Chicago, Illinois. He also lived in Hudson, Ohio, as a child. He attended The Hill School and took two years longer than usual to graduate, before entering the Sheffield Scientific School at Yale University. His academic performance was poor, and he subsequently enrolled at Columbia University and McGill before ending his academic career. Lincoln Ellsworth's father, James, a wealthy coal man from the United States, spent US$100,000 to fund Roald Amundsen's 1925 attempt to fly from Svalbard to the North Pole. Amundsen, accompanied by Lincoln Ellsworth, pilot Hjalmar Riiser-Larsen, flight mechanic Karl Feucht and two other team members, set out in two Dornier Wal flying boats, the N24 and N25, in an attempted to reach the ...

Mount Craddock
Mount Craddock is a large, bold mountain forming the south extremity of Craddock Massif in Sentinel Range, the ninth highest mountain in Antarctica. It is linked by Karnare Col to Mount Strybing in the southern Sentinel Range. The ninth-highest mountain in Antarctica was first climbed in January 1992. The name Mount Craddock was originally recommended by the Advisory Committee on Antarctic Names (US-ACAN) in 1965 for the present-day Craddock Massif but subsequent maps limited Mount Craddock to the massif's southernmost peak, a position that became established over years. To avoid confusion and to fix the position of the name, US-ACAN redefined Mount Craddock in 2006 to apply to the southernmost peak described above.USGS GNIS The mountain was named by US-ACAN for J. Campbell Craddock (1930–2006), leader of a University of Minnesota expedition (1962–63) that made geological investigations and cartographic surveys in the Sentinel and Heritage Ranges of the Ellsworth Mountain ...
