Retrospect Spur
Separation Range () is the northeastern branch of the Commonwealth Range in the Queen Maud Mountains, Antarctica. The branch starts at about 84°20'S, and forms two chains of mountains separated by Hood Glacier. The Separation Range, about long, terminates to the north at the Ross Ice Shelf. Named by the New Zealand Alpine Club Antarctic Expedition, 1959–60. Location The Separation range lies to the east of the northern part of the Commonwealth Range, and runs from south to north between that range and the Canyon Glacier to the east. The Cunningham Glacier enters the Canyon Glacier just south of the southern end of the Searation Range. The northern end adjoins the Ross Ice Shelf The Ross Ice Shelf is the largest ice shelf of Antarctica (, an area of roughly and about across: about the size of France). It is several hundred metres thick. The nearly vertical ice front to the open sea is more than long, and between high .... The Hood Glacier defines its western edge. ...

Queen Maud Mountains
The Queen Maud Mountains () are a major group of mountains, ranges and subordinate features of the Transantarctic Mountains, lying between the Beardmore Glacier, Beardmore and Reedy Glaciers and including the area from the head of the Ross Ice Shelf to the Antarctic Plateau in Antarctica. Captain Roald Amundsen and his South Pole party ascended Axel Heiberg Glacier near the central part of this group in November 1911, naming these mountains for the Norwegian queen Maud of Wales. Exploration and naming Elevations bordering the Beardmore Glacier, at the western extremity of these mountains, were observed by the British expeditions led by Ernest Shackleton (1907–09) and Robert Falcon Scott (1910-13), but the mountains as a whole were mapped by several American expeditions led by Richard Evelyn Byrd (1930s and 1940s), and United States Antarctic Program (USARP) and New Zealand Antarctic Research Program (NZARP) expeditions from the 1950s through the 1970s.

Commonwealth Range
The Commonwealth Range () is a north-south trending range of rugged mountains, long, located within the Queen Maud Mountains on the Dufek Coast of the continent of Antarctica. The range borders the eastern side of Beardmore Glacier from Keltie Glacier to the Ross Ice Shelf. The range is southeast of the Queen Alexandra Range, which is to the west of the Beardmore Glacier. It is west of the Hughes Range (Antarctica), Hughes Range and north of the Supporters Range and the Barton Mountains. Discovery and naming The range was discovered by the British Antarctic Expedition, 1907–09 and named by them after the Commonwealth of Australia, which gave much assistance to the expedition. Location The Commonwealth Range runs from south to north along the east side of the Beardmore Glacier. Towards its southeast the Pain Névé feeds the Keltie Glacier, which flows southwest, then west, then north round the southern tip of the range to join the Beardmore Glacier. The Canyon Glacier forms ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hood Glacier
Hood Glacier () is a glacier about long draining northward from Siege Dome in the Commonwealth Range of Antarctica. It enters the Ross Ice Shelf between the Commonwealth Range and the Separation Range. The glacier was discovered by the Southern Polar Party of the 1907–1909 British Antarctic Expedition, under Ernest Shackleton, and was named for Admiral Sir Horace Hood, under whom Jameson Adams Sir Jameson Boyd Adams (6 March 1880 – 30 April 1962) was a British Antarctic explorer and Royal Naval Reserve officer. He participated in the Nimrod expedition, ''Nimrod'' expedition, the first expedition led by Ernest Shackleton in an ..., a member of the party, had served in .

Ross Ice Shelf
The Ross Ice Shelf is the largest ice shelf of Antarctica (, an area of roughly and about across: about the size of France). It is several hundred metres thick. The nearly vertical ice front to the open sea is more than long, and between high above the water surface. Ninety percent of the floating ice, however, is below the water surface. Most of the Ross Ice Shelf is in the Ross Dependency claimed by New Zealand. It floats in, and covers, a large southern portion of the Ross Sea and the entire Roosevelt Island, Antarctica, Roosevelt Island located in the east of the Ross Sea. The ice shelf is named after James Clark Ross, Sir James Clark Ross, who discovered it on 28 January 1841. It was originally called "The Barrier", with various adjectives including "Great Ice Barrier", as it prevented sailing further south. Ross mapped the ice front eastward to 160° W. In 1947, the U.S. Board on Geographic Names applied the name "Ross Shelf Ice" to this feature and published it in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canyon Glacier
Canyon Glacier () is a narrow glacier, long, flowing to the Ross Ice Shelf. It drains the northwest slopes of Mount Wexler and moves northward between steep canyon walls of the Separation Range and Hughes Range (Antarctica), Hughes Range to join the ice shelf immediately west of Giovinco Ice Piedmont. The glacier was observed from nearby Mount Patrick by the New Zealand Alpine Club Antarctic Expedition (1959–60) who gave the descriptive name. Location The Canyon Glacier rises to the north of the Pain Névé, below Mount Wexler in the Hughes Range (Antarctica), Hughes Range to the east. The Commonwealth Range is to the west, including Mount Hermanson and Gray Peak (Antarctica), Gray Peak, which overlook the upper reaches. The Canyon Glacier flows north and is joined by the Cunningham Glacier from the left (west). It continues north past the Separation Range along its west side. At its mouth it passes the Nadeau Bluff and the Giovinco Ice Piedmont to the east and Mount Cope to it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mountain Ranges Of Antarctica
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 isolated summits, but most occur in mountain ranges. Mountains are formed through 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 slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain and climate, mountains te ...
