Bell Bluff
The Cloudmaker () is a massive mountain, high, standing at the west side of Beardmore Glacier, just south of Hewson Glacier in the Queen Alexandra Range, Antarctica. It is easily identifiable by its high, ice-free slope facing Beardmore Glacier. Exploration and name The Cloudmaker was discovered by the British Antarctic Expedition, 1907–09, and so named because of a cloud which usually appeared near the summit, providing a useful landmark during their journey up the Beardmore Glacier. Location The Cloudmaker lies on the west margin of Beardmore Glacier, to the north of Cherry Icefall and south of Hewson Glacier. It is northeast of Mount Dickerson and southeast of Grindley Plateau. Morrison Hills extend along the northern side of Hewson Glacier, and Bell Bluff is further north. Nearby features Morrison Hills . A series of rugged E-W trending hills between Garrard Glacier and Hewson Glacier. Named by the United States Advisory Committee on Antarctic Names (US-ACAN) aft ...

Antarctica
Antarctica () is Earth's southernmost and least-populated continent. Situated almost entirely south of the Antarctic Circle and surrounded by the Southern Ocean (also known as the Antarctic 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 Climate of Antarctica#Precipitation, 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 temperature recorded on Earth, lowest measured temperature on Earth, . The coastal regions can reach temperatures over in the ...

Queen Alexandra Range
The Queen Alexandra Range () is a major mountain range about long, bordering the entire western side of Beardmore Glacier from the Polar Plateau to the Ross Ice Shelf. The range is in the Transantarctic Mountains System, and is located in the Ross Dependency region of Antarctica. Discovery The Queen Alexandra Range was discovered on the journey toward the South Pole by the British Antarctic Expedition, 1907–09 (BrAE), and was named by Ernest Shackleton for Queen Alexandra, Queen of the United Kingdom, 1901-10. Shackleton and his men, and a later expedition headed by Robert Falcon Scott, both collected rock samples from the range that contained fossils. The discovery that multicellular life forms had lived so close to the South Pole was an additional piece of evidence that accompanied the publication (in 1910 and independently in 1912) of the theory of continental drift. Location The Queen Alexandra Range is bounded by the Beardmore Glacier along its southeast edge, which divi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beardmore Glacier
The Beardmore Glacier in Antarctica is one of the largest valley glaciers in the world, being long and having a width of . It descends about from the Antarctic Plateau to the Ross Ice Shelf and is bordered by the Commonwealth Range of the Queen Maud Mountains on the eastern side and the Queen Alexandra Range of the Central Transantarctic Mountains on the western. Its mouth is east of the Lennox-King Glacier. It is northwest of the Ramsey Glacier. Early exploration The glacier is one of the main passages through the Transantarctic Mountains to the great polar plateau beyond, and was one of the early routes to the South Pole despite its steep upward incline. The glacier was discovered and climbed by Ernest Shackleton during his Nimrod Expedition, ''Nimrod'' Expedition of 1908. Although Shackleton turned back at latitude 88° 23' S, just from the South Pole, he established the first proven route towards the pole and, in doing so, became the first person to set foot up ...

British Antarctic Expedition, 1907–09
The ''Nimrod'' Expedition of 1907–1909, otherwise known as the British Antarctic Expedition, was the first of three expeditions to the Antarctic led by Ernest Shackleton and his second time to the Continent. Its main target, among a range of geographical and scientific objectives, was to be first to reach the South Pole. This was not attained, but the expedition's southern march reached a Farthest South latitude of 88° 23' S, just from the pole. This was by far the longest southern polar journey to that date and a record convergence on either Pole. A separate group led by Welsh Australian geology professor Edgeworth David reached the estimated location of the South magnetic pole, and the expedition also achieved the first ascent of Mount Erebus, Antarctica's second highest volcano. The expedition lacked governmental or institutional support, and relied on private loans and individual contributions. It was beset by financial problems and its preparations were hur ...

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] |
Operation Deep Freeze
Operation Deep Freeze is the code name for a series of United States missions to Antarctica, beginning with "Operation Deep Freeze I" in 1955–56, followed by "Operation Deep Freeze II", "Operation Deep Freeze III", and so on. (There was an initial operation before Richard E. Byrd, Admiral Richard Byrd proposed 'Deep Freeze'). Given the continuing and constant US presence in Antarctica since that date, "Operation Deep Freeze" has come to be used as a general term for US operations in that continent, and in particular for the regular missions to resupply US Antarctic bases, coordinated by the Military of the United States, United States military. Task Force 199 was involved. For a few decades the missions were led by the United States Navy, though the Air National Guard and National Science Foundation are also important parts of the missions. In Antarctica, when the polar dawn starts late in the year things begin warming up and the mission usually runs from late in the year to ear ...

Hallett Station
Cape Hallett is a snow-free area (Antarctic oasis) on the northern tip of the Hallett Peninsula on the Ross Sea coast of Victoria Land, East Antarctica. Cape Adare lies to the north. History In 1956, during Operation Deep Freeze II, was damaged by an ice floe at Cape Hallett. On 16 October 1958, a Douglas C-124C Globemaster II (52-1017) of the USAF crashed into a 3200-foot mountain near Cape Hallett Bay while maneuvering, killing 7 of the 13 occupants. The Globemaster was on an airdrop flight from Christchurch to McMurdo Station and other navigational errors had occurred prior to the crash. Hallett Station The cape was the location of a joint scientific base, Hallett Station, between the United States and New Zealand during the International Geophysical Year of 1957, and was manned permanently until 1964, when there was a major fire. It was then used as a summer only base until 1973. The site is currently being remediated by removing hazardous materials: fuel, and oi ...
