Crossover Pass

	Crossover Pass Crossover Pass is a pass between Gordon Glacier and Cornwall Glacier (Coats Land), Cornwall Glacier in the central part of the Shackleton Range in Antarctica. It was first mapped in 1957 by the Commonwealth Trans-Antarctic Expedition and so named because this pass, together with Gordon and Cornwall Glaciers, provides a sledging route across the Shackleton Range from north to south.

	Gordon Glacier Gordon Glacier () is an Antarctic glacier of at least in length flowing in a northerly direction beginning in the Crossover Pass, flowing through the Shackleton Range to finally meet the Slessor Glacier. The glacier was first mapped in 1957 by the Commonwealth Trans-Antarctic Expedition, CTAE, and named after George Patrick Pirie-Gordon, 15th Laird of Buthlaw (died 4 April 2011), who was a member of the Committee of Management and treasurer of the CTAE between 1955 and 1958.

	Cornwall Glacier (Coats Land) Cornwall Glacier () is a glacier long, flowing south from Crossover Pass in the Shackleton Range to join Recovery Glacier east of Ram Bow Bluff. It was first mapped in 1957 by the Commonwealth Trans-Antarctic Expedition, and named for General Sir James Handyside Marshall-Cornwall, a member of the Committee of Management of the Commonwealth Trans-Antarctic Expedition, 1955–58.

	Shackleton Range The Shackleton Range is a mountain range in Antarctica. Rising at Holmes Summit to , it extends in an east–west direction for about between the Slessor and Recovery glaciers. The range was named after Sir Ernest Shackleton, leader of the British Imperial Trans-Antarctic Expedition (or "Shackleton's Expedition") of 1914–16. Surveys The Commonwealth Trans-Antarctic Expedition (CTAE), which in 1956 saw the range from the air, conducted a ground-level survey of its western part in 1957. The United States Navy photographed the range from the air in 1967. In 1968–69 and 1969–70, the British Antarctic Survey (based at Halley Station) conducted further ground surveys with support from US Navy C-130 Hercules aircraft. Geology The Haskard Group and Turnpike Bluff Group rest unconformably on the Archean-Middle Proterozoic Shackleton Range Metamorphic Complex. The Ordovician-Early Devonian Blaiklock Glacier Group (475 Ma) also unconformably overlies the Shackleton Range Metam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	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]
picture info	Commonwealth Trans-Antarctic Expedition The Commonwealth Trans-Antarctic Expedition (CTAE) of 1955–1958 was a Commonwealth-sponsored expedition that successfully completed the first overland crossing of Antarctica, via the South Pole. It was the first expedition to reach the South Pole overland for 46 years, preceded only by Amundsen's expedition and Scott's expedition in 1911 and 1912. In keeping with the tradition of polar expeditions of the Heroic Age of Antarctic Exploration, the CTAE was a private venture, though it was supported by the governments of the United Kingdom, New Zealand, United States, Australia and South Africa, as well as many corporate and individual donations, under the patronage of Queen Elizabeth II. It was headed by British explorer Vivian Fuchs, with New Zealander Sir Edmund Hillary leading the New Zealand Ross Sea Support team. The New Zealand party included scientists participating in International Geophysical Year research while the British team were separately based at Halley Ba ...

picture info	Mountain Passes 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 300 metres (1,000 feet) 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 ...
