Devils Corrie
Devils Corrie () is a large and very spectacular cirque, or corrie, midway between Olivine Point and Amphibolite Point on the south coast of Coronation Island in the South Orkney Islands. It was named 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 ... following their survey of 1948–49. Devils Peak is named after the corrie. References Cirques of Antarctica Landforms of the South Orkney Islands {{SouthOrkneys-geo-stub ...

Cirque
A (; from the Latin word ') is an amphitheatre-like valley formed by glacial erosion. Alternative names for this landform are corrie (from Scottish Gaelic , meaning a pot or cauldron) and (; ). A cirque may also be a similarly shaped landform arising from fluvial erosion. The concave shape of a glacial cirque is open on the downhill side, while the cupped section is generally steep. Cliff-like slopes, down which ice and glaciated debris combine and converge, form the three or more higher sides. The floor of the cirque ends up bowl-shaped, as it is the complex convergence zone of combining ice flows from multiple directions and their accompanying rock burdens. Hence, it experiences somewhat greater erosion forces and is most often overdeepened below the level of the cirque's low-side outlet (stage) and its down-slope (backstage) valley. If the cirque is subject to seasonal melting, the floor of the cirque most often forms a tarn (small lake) behind a dam, which marks the ...

Olivine Point
Olivine Point () is the southern end of the low-lying peninsula which forms the east limit of Iceberg Bay on the south coast of Coronation Island, in the South Orkney Islands. Surveyed 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) in 1948–49, and so named by them because the mineral olivine occurs in the igneous dikes intersecting the peninsula just north of the point.

Amphibolite Point
Amphibolite Point () is a conspicuous, pyramidal point northwest of Saunders Point on the south coast of Coronation Island, in the South Orkney Islands. It was named by the Falkland Islands Dependencies Survey following their survey of 1948–49; there is a large amount of amphibolite on this point. Avalanche Corrie is an ice-filled cirque A (; from the Latin word ') is an amphitheatre-like valley formed by glacial erosion. Alternative names for this landform are corrie (from Scottish Gaelic , meaning a pot or cauldron) and (; ). A cirque may also be a similarly shaped landform ..., or corrie, close north of Amphibolite Point. It was so named by the Falkland Islands Dependencies Survey, because of the continuous avalanches from the hanging glaciers above the corrie.

Coronation Island
Coronation Island is the largest of the South Orkney Islands, long and from wide. The island extends in a general east–west direction, is mainly ice-covered and comprises numerous bays, glaciers and peaks, the highest rising to . History The island was discovered in December 1821, in the course of the joint cruise by Captain Nathaniel Palmer, an American sealer, and Captain George Powell, a British sealer. Powell named the island in honour of the coronation of George IV, who had become king of the United Kingdom in 1820. Antarctic Specially Protected Area An area of some 92 km2 of north-central Coronation Island has been designated an Antarctic Specially Protected Area (ASPA 114), mainly for use as a relatively pristine reference site for use in comparative studies with more heavily impacted sites. It extends northwards from Brisbane Heights and Wave Peak in the central mountains to the coast between Conception Point in the west to Foul Point in the east. Most ...

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 British Admiralty, Admiralty and the Secretary of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Devils Peak (Antarctica)
Devils Peak () is a conspicuous rocky peak, 735 m, between Sunshine Glacier and Devils Corrie on the south side of Coronation Island, in the South Orkney Islands. Surveyed in 1948-49 by the Falkland Islands Dependencies Survey (FIDS), who so named it because of its proximity to Devils Corrie. Mountains of the South Orkney Islands {{SouthOrkneys-geo-stub ...
