Block Mountain, Antarctica
Block Mountain () is a prominent block-shaped mountain with a height of 1,460 m. The feature juts east from the Douglas Range of Alexander Island immediately south of Transition Glacier in Antarctica. Its north, east, and south sides features sharply defined corners which are nearly vertical. From its northeast corner, a low spur connects this mountain with Tilt Rock. The mountain was first photographed from the air on November 23, 1935, by Lincoln Ellsworth and mapped from these photos by W.L.G. Joerg. It was roughly surveyed in 1936 by the British Graham Land Expedition (BGLE) and resurveyed in 1949 by the Falkland Islands Dependencies Survey The British Antarctic Survey (BAS) is the United Kingdom's national polar research institute. It has a dual purpose, to conduct polar science, enabling better understanding of global issues, and to provide an active presence in the Antarctic on ... (FIDS). The descriptive name was given by FIDS. References {{AlexanderIsland-ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Douglas Range
The Douglas Range () is a sharp-crested range, with peaks rising to 3,000 metres, extending 120 km (75 mi) in a northwest–southeast direction from Mount Nicholas to Mount Edred and forming a steep east escarpment of Alexander Island within the British Antarctic Territory, overlooking the north part of George VI Sound. Geography History Mount Nicholas was seen in 1909 from a distance by the French Antarctic Expedition under Charcot. The full extent of the range was observed by Lincoln Ellsworth on his trans-Antarctic flight of November 23, 1935, and its east escarpment first roughly mapped from air photos taken on that flight by W.L.G. Joerg. The east face of the range was roughly surveyed from George VI Sound by the British Graham Land Expedition (BGLE) in 1936 and resurveyed by the Falkland Islands Dependencies Survey (FIDS) in 1948–50. The entire range, including the west slopes, was mapped in detail from air photos taken by the Ronne Antarctic Research ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alexander Island
Alexander Island, which is also known as Alexander I Island, Alexander I Land, Alexander Land, Alexander I Archipelago, and Zemlja Alexandra I, is the largest island of Antarctica. It lies in the Bellingshausen Sea west of Palmer Land, Antarctic Peninsula from which it is separated by Marguerite Bay and George VI Sound. The George VI Ice Shelf entirely fills George VI Sound and connects Alexander Island to Palmer Land. The island partly surrounds Wilkins Sound, which lies to its west.Stewart, J. (2011) ''Antarctic An Encyclopedia'' McFarland & Company Inc, New York. 1776 pp. . Alexander Island is about long in a north–south direction, wide in the north, and wide in the south. Alexander Island is the second-largest uninhabited island in the world, after Devon Island. History Alexander Island was discovered on January 28, 1821, by a Russian expedition under Fabian Gottlieb von Bellingshausen, who named it Alexander I Land for the reigning Tsar Alexander I of Russia.

Transition Glacier
Transition Glacier () is a glacier extending along the east coast of Alexander Island, 8 nautical miles (15 km) long and 2 nautical miles (3.7 km) wide, which flows east into the George VI Ice Shelf that occupies George VI Sound along the north side of Block Mountain and Tilt Rock. The glacier was first photographed from the air on November 23, 1935, by Lincoln Ellsworth and mapped from these photos by W.L.G. Joerg. Surveyed in 1949 by the Falkland Islands Dependencies Survey, and so named by them because this glacier marks the transition between igneous rocks to the north and sedimentary rocks to the south.

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] |
Tilt Rock
Tilt Rock () is an isolated rock peak, rising to about 670 m, situated 2 nautical miles (3.7 km) inland from the George VI Ice Shelf of George VI Sound and 2 nautical miles (3.7 km) northeast of Block Mountain in eastern Alexander Island, Antarctica. This rock formation was first photographed from the air on November 23, 1935, by Lincoln Ellsworth and later mapped from these photos by W.L.G. Joerg. Roughly surveyed from the ground in 1936 by the British Graham Land Expedition and resurveyed in 1948-49 by the Falkland Islands Dependencies Survey The British Antarctic Survey (BAS) is the United Kingdom's national polar research institute. It has a dual purpose, to conduct polar science, enabling better understanding of global issues, and to provide an active presence in the Antarctic on .... So named by FIDS because of its tilted and possibly unstable appearance. References Rock formations on Alexander Island {{AlexanderIsland-geo-stub ...

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 ...

Falkland Islands Dependencies Survey
The British Antarctic Survey (BAS) is the United Kingdom's national polar research institute. It has a dual purpose, to conduct polar science, enabling better understanding of global issues, and to provide an active presence in the Antarctic on behalf of the UK. It is part of the Natural Environment Research Council (NERC). With over 400 staff, BAS takes an active role in Antarctic affairs, operating five research stations, one ship and five aircraft in both polar regions, as well as addressing key global and regional issues. This involves joint research projects with over 40 UK universities and more than 120 national and international collaborations. Having taken shape from activities during World War II, it was known as the Falkland Islands Dependencies Survey until 1962. History Operation Tabarin was a small British expedition in 1943 to establish permanently occupied bases in the Antarctic. It was a joint undertaking by the Admiralty and the Colonial Office.
