Ebony Wall
Ebony Wall () is a dark, nearly vertical rock wall in Antarctica, which rises about at the head of Pettus Glacier. The wall is about long and forms a part of the western escarpment of Detroit Plateau near the base of Trinity Peninsula. It was charted in 1948 by the Falkland Islands Dependencies Survey who applied the descriptive name. Map Trinity Peninsula.Scale 1:250000 topographic map No. 5697.

Pettus Glacier
Pettus Glacier () is a narrow deeply entrenched glacier 9 nautical miles (17 km) long, which flows north from Ebony Wall into Gavin Ice Piedmont between Poynter Hill and Tinsel Dome, Trinity Peninsula. Named by United Kingdom Antarctic Place-Names Committee (UK-APC) for Robert N. Pettus, aircraft pilot with Falkland Islands and Dependencies Aerial Survey Expedition (FIDASE), 1956–57.

Detroit Plateau
Detroit Plateau () is a major interior plateau of Graham Land on the Antarctic Peninsula, with heights between . Its northeast limit is marked by the south wall of Russell West Glacier, from which it extends some in a general southwest direction to Herbert Plateau. The plateau was observed from the air by Sir Hubert Wilkins on a flight of December 20, 1928. Wilkins named it Detroit Aviation Society Plateau after the society which aided in the organizing of his expedition, but the shortened form of the original name is approved. The north and east sides of the plateau were charted by the Falkland Islands Dependencies Survey in 1946–47. Dinsmoor Glacier flows east from the south edge of Detroit Plateau.

Trinity Peninsula
Trinity Peninsula is the northernmost part of the Antarctic Peninsula. It extends northeastward for about 130 km (80 mi) to Cape Dubouzet from an imaginary line connecting Cape Kater on the north-west coast and Cape Longing on the south-east coast. Prime Head is the northernmost point of this peninsula. Some 20 kilometers southeast of Prime Head is Hope Bay with the year-round Argentinian Esperanza Base. History It was first sighted on 30 January 1820 by Edward Bransfield, Master, Royal Navy, immediately after his charting of the newly discovered South Shetland Islands nearby. In the century following the peninsula's discovery, chartmakers used various names (Trinity Land, Palmer Land, and Land of Louis Philippe) for this portion of it, each name having some historical merit. The recommended name derives from "Trinity Land", given by Bransfield during 1820 in likely recognition of the Corporation of Trinity House, Britain's historical maritime pilotage authority, alth ...

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] |
