Lurabee Glacier
Lurabee Glacier () is a glacier long, flowing northeast between the Scripps Heights and Finley Heights to the east coast of Palmer Land, Antarctica. This glacier was discovered by Sir Hubert Wilkins on December 20, 1928, on his pioneer Antarctic flight. He named it "Lurabee Channel" for Lurabee Shreck of San Francisco, in recognition of her aid in procuring equipment for this and an earlier Arctic flight, and for her editorial assistance on his book ''Flying the Arctic''. The term channel has been amended to glacier, in keeping with the true nature of the feature.

Glacier
A glacier (; ) is a persistent body of dense ice that is constantly moving under its own weight. A glacier forms where the accumulation of snow exceeds its Ablation#Glaciology, ablation over many years, often Century, centuries. It acquires distinguishing features, such as Crevasse, crevasses and Serac, seracs, as it slowly flows and deforms under stresses induced by its weight. As it moves, it abrades rock and debris from its substrate to create landforms such as cirques, moraines, or fjords. Although a glacier may flow into a body of water, it forms only on land and is distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water. On Earth, 99% of glacial ice is contained within vast ice sheets (also known as "continental glaciers") in the polar regions, but glaciers may be found in mountain ranges on every continent other than the Australian mainland, including Oceania's high-latitude oceanic island countries such as New Zealand.

Scripps Heights
Scripps Heights () is a rugged heights which are largely ice-covered, surmounting the peninsula between Casey Glacier and Lurabee Glacier on the east coast of Palmer Land, Antarctica. Deeply scarred by glaciers, the heights terminate on the east in Cape Walcott. Discovered by Sir Hubert Wilkins in his pioneer flight on December 20, 1928. Thinking the feature to be a large island lying between two great transverse channels which completely severed Antarctic Peninsula, he named it Scripps Island for William Scripps of Detroit, Michigan. Correlation of aerial photographs taken by Lincoln Ellsworth in 1935 and preliminary reports of the findings of the British Graham Land Expedition (BGLE) under Rymill, 1934–37, led W.L.G. Joerg to interpret this to be a peninsula. In published reports, members of the BGLE have concurred in this interpretation which was also borne out by the results of subsequent flights and a sledge trip from East Base by members of the United States Antarctic S ...

Finley Heights
Stefansson Strait () is an ice-filled strait 35 nautical miles (60 km) long and 3 to 10 nautical miles (18 km) wide, between the east coast of Palmer Land, there called ''Wilkins Coast'', and Hearst Island. This strait was first sighted by Sir Hubert Wilkins at the south end of his flight of December 20, 1928, and was named by him for Vilhjalmur Stefansson. He believed it to be a strait cutting off what is now known to be Antarctic Peninsula The Antarctic Peninsula, known as O'Higgins Land in Chile and Tierra de San Martín in Argentina, and originally as Graham Land in the United Kingdom and the Palmer Peninsula in the United States, is the northernmost part of mainland Antarctic ... from the main land mass of Antarctica. The true orientation of the strait was determined by members of the United States Antarctic Service (USAS) who charted this coast by land and from the air in 1940.

Palmer Land
Palmer Land () is the portion of the Antarctic Peninsula, Antarctica that lies south of a line joining Cape Jeremy and Cape Agassiz. This application of Palmer Land is consistent with the 1964 agreement between the Advisory Committee on Antarctic Names and the UK Antarctic Place-Names Committee, in which the name Antarctic Peninsula was approved for the major peninsula of Antarctica, and the names Graham Land and Palmer Land for the northern and southern portions, respectively. The line dividing them is roughly 69° S. Boundaries In its southern extreme, the Antarctic Peninsula stretches west, with Palmer Land eventually bordering Ellsworth Land along the 80° W line of longitude. Palmer Land is bounded in the south by the ice-covered Carlson Inlet, an arm of the Filchner-Ronne Ice Shelf, which crosses the 80° W line. This is the base of Cetus Hill. This feature is named after Nathaniel Palmer, an American sealer who explored the Antarctic Peninsula area southward of Deceptio ...

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] |
Sir Hubert Wilkins
Sir George Hubert Wilkins MC & Bar (31 October 188830 November 1958), commonly referred to as Captain Wilkins, was an Australian polar explorer, ornithologist, pilot, soldier, geographer and photographer. He was awarded the Military Cross after he assumed command of a group of American soldiers who had lost their officers during the Battle of the Hindenburg Line, and became the only official Australian photographer from any war to receive a combat medal. He narrowly failed in an attempt to be the first to cross under the North Pole in a submarine, but was able to prove that submarines were capable of operating beneath the polar ice cap, thereby paving the way for future successful missions. The US Navy later took his ashes to the North Pole aboard the submarine USS ''Skate'' on 17 March 1959. Early life Hubert Wilkins was a native of Mount Bryan East, South Australia, the last of 13 children in a family of pioneer settlers and sheep farmers. He was born at Mount Bryan East, ...

Arctic
The Arctic ( or ) is a polar regions of Earth, polar region located at the northernmost part of Earth. The Arctic consists of the Arctic Ocean, adjacent seas, and parts of Canada (Yukon, Northwest Territories, Nunavut), Danish Realm (Greenland), Finland, Iceland, Norway, Russia (Murmansk Oblast, Murmansk, Siberia, Nenets Autonomous Okrug, Nenets Okrug, Novaya Zemlya), Sweden and the United States (Alaska). Land within the Arctic region has seasonally varying snow and sea ice, ice cover, with predominantly treeless permafrost (permanently frozen underground ice) containing tundra. Arctic seas contain seasonal sea ice in many places. The Arctic region is a unique area among Earth's ecosystems. The cultures in the region and the Arctic indigenous peoples have adapted to its cold and extreme conditions. Life in the Arctic includes zooplankton and phytoplankton, fish and marine mammals, birds, land animals, plants and human societies. Arctic land is bordered by the subarctic. De ...

Hogmanay Pass
Hogmanay Pass () is a pass high, immediately southwest of the Scripps Heights, leading from the head of Casey Glacier to the middle of Lurabee Glacier, in northeastern Palmer Land, Antarctica. The feature was first photographed from the air by Lincoln Ellsworth in November 1935, and its southern portion was plotted from these photos by W.L.G. Joerg. It was rephotographed by the United States Antarctic Service in 1940, and by the Ronne Antarctic Research Expedition in 1947. This pass was used by a Falkland Islands Dependencies Survey survey party in December 1960 and provided a good sledge route. It was so named because the pass was approached on the last day of 1960, the Scottish feast of Hogmanay Hogmanay ( , ) is the Scots word for the last day of the old year and is synonymous with the celebration of the New Year in the Scottish manner. It is normally followed by further celebration on the morning of New Year's Day (1 January) or i .... References Mountain passes of ...
