Thurston Island is a largely ice-covered, glacially dissected island, 135 nautical miles long and 55 nautical miles wide, lying between Amundsen Sea and Bellingshausen Sea a short way off the northwest end of Ellsworth Land, Antarctica. The island is separated from the mainland by Peacock Sound, which is occupied by the west portion of Abbot Ice Shelf.
Leppard Glacier is a large valley glacier draining east between the Aristotle Mountains and Voden Heights, and flowing into Scar Inlet north of Ishmael Peak, on the east coast of Graham Land, Antarctica. The glacier was first seen from the air and photographed in part by Hubert Wilkins on December 20, 1928, and was surveyed by the Falkland Islands Dependencies Survey (FIDS) in 1955. It is now clear that, on the photographic evidence of his outward flight, Wilkins gave the name "Crane Channel" to this glacier, and that on his return flight he photographed what is now accepted as Crane Glacier, perhaps thinking that it was the same feature. Since Crane Glacier has been retained for the northern of these glaciers photographed by Wilkins, the UK Antarctic Place-Names Committee has named this feature for Norman A.G. Leppard, assistant surveyor with the FIDS, who surveyed this area in 1955.
The Willis Islands are a small archipelago to the west of South Georgia Island in the South Georgia Islands. They are 2 miles (3.2 km) west of Bird Island, separated by the Stewart Strait. They were discovered on 14 January 1775 by Captain James Cook and named for Cook's midshipman Thomas Willis, the crew member who first sighted them. The Willis Islands were charted in greater detail and individually named by Discovery Investigations (DI) personnel between 1926 and 1930.
The Welcome Islands are a small rocky archipelago to the north of the main island of South Georgia. They are to the east of Bird Island.
Cape Harcourt is a headland on the eastern extremity of Harcourt Island on the north coast of South Georgia, forming the north side of the entrance to Royal Bay. The name dates back to at least 1920 and is now well established. Sacramento Bight lies on the coast between Cape Harcourt and Calf Head.
Moraine Fjord is an inlet 3.5 nautical miles long with a reef extending across its entrance, forming the west head of Cumberland East Bay, South Georgia. It was charted by the Swedish Antarctic Expedition under Otto Nordenskjöld, 1901–04, who so named it because of the large glacial moraine at its entrance.
Acosta Glacier is a glacier about 2 miles (3 km) long flowing north from Thurston Island just east of Dyer Point in Antarctica. It was named by the Advisory Committee on Antarctic Names (US-ACAN) after Alex V. Acosta of the United States Geological Survey (USGS) in Flagstaff, Arizona. He is a computer and graphic specialist, and was part of the USGS team that compiled the 1:5,000,000-scale Advanced Very High Resolution Radiometer satellite image maps of Antarctica and the 1:250,000-scale Landsat image maps of the Siple Coast area in the 1990s.
Esbensen Bay is a small bay 1 nautical mile (2 km) southwest of Nattriss Head, along the southeast end of South Georgia. It was charted by the Second German Antarctic Expedition, 1911–12, under Filchner, and was named for Captain Viktor Esbensen, manager of the Compañía Argentina de Pesca whaling station at Grytviken, the first land-based whaling station in Antarctica.
Helland Glacier is a glacier 4 nautical miles (7 km) long flowing southwest from Mount Paget to Rocky Bay, on the south side of South Georgia. It was mapped by Olaf Holtedahl during his visit to South Georgia in 1927–28, and named by him for Amund Helland, a Norwegian mining geologist and glaciologist.
Herz Glacier is a glacier flowing southeast from the vicinity of Mount Paterson to the east coast of South Georgia. It was named by the Second German Antarctic Expedition under Wilhelm Filchner, 1911–12.
Breitfuss Glacier is a glacier 10 nautical miles (19 km) long, which flows southeast from Avery Plateau into Mill Inlet to the west of Cape Chavanne, on the east coast of Graham Land. It was charted by the Falkland Islands Dependencies Survey (FIDS) and photographed from the air by the Ronne Antarctic Research Expedition in 1947. It was named by the FIDS for Leonid Breitfuss, a German polar explorer, historian, and author of many polar bibliographies.
Tussock Island is an island 0.2 nautical miles (0.4 km) long, lying off the west side of Annenkov Island, South Georgia. Following geological work by British Antarctic Survey (BAS), 1972–73, it was named after the thick mantle of tussock grass that grows on the island.
Turner Glacier is a glacier on the east side of Mount Liotard flowing northeast into Ryder Bay, Adelaide Island. The glacier was surveyed by Falkland Islands Dependencies Survey (FIDS), 1948, and photographed from the air by Falkland Islands and Dependencies Aerial Survey Expedition (FIDASE), 1956–57. Named by the United Kingdom Antarctic Place-Names Committee (UK-APC) in 1977 after Andrew John Turner, British Antarctic Survey (BAS) builder, Halley Station, 1973–74; Signy Island, 1974–75; Rothera Station, 1976–77, 1978–80; and Faraday Station, 1982–83.
Dodman Island is an island 6.5 km (4.0 mi) long, lying 7.4 km (4.6 mi) south-east of Rabot Island and 18.5 km (11.5 mi) west of Ferin Head, off the west coast of Graham Land, Antarctica. The island was charted and named by the British Graham Land Expedition, 1934–37, under John Rymill.
Eldred Glacier is a glacier 2.5 nautical miles (5 km) long, flowing to the north coast of King George Island immediately east of Potts Peak, in the South Shetland Islands. It was named by the UK Antarctic Place-Names Committee in 1960 for Andrew J. Eldred, Master of the sealing vessel Thomas Hunt from Stonington, Connecticut, who visited the South Shetland Islands in 1873–74, 1875–76, 1878–79 and 1879–80. During the latter season he took part in the unsuccessful search for the Charles Shearer.
Flatiron Valley is a north-south valley including a sub-glacial lake, located in the south part of the Ganymede Heights, marginal to Jupiter Glacier, situated in eastern Alexander Island, Antarctica. The name derives from field work in 1978–79 by the Department of Geography, University of Aberdeen, Scotland, with British Antarctic Survey support. It was named from the triangular slope facets between prominent gullies on the west side of the valley. The site lies within Antarctic Specially Protected Area (ASPA) No.147.
Green Glacier is a glacier on the east side of Graham Land, Antarctica, 15 nautical miles (28 km) long and 4 nautical miles (7 km) wide, flowing from the plateau northeast between Dugerjav Peak and Rugate Ridge, and then east into Vaughan Inlet next north of Pirne Peak and south of the terminus of Hektoria Glacier.
McArthur Glacier is a glacier between the Christie Peaks and Swine Hill, flowing west from Palmer Land, Antarctica, into George VI Sound. It was named by the UK Antarctic Place-Names Committee for Alistair H. McArthur, a British Antarctic Survey geophysicist at Stonington Island, 1967–68.
The Madder Cliffs are reddish rock cliffs which form the north side of the entrance to Suspiros Bay, at the west end of Joinville Island, Antarctica. They rise steeply from the sea to about 305 metres (1,000 ft). The cliffs were surveyed by the Falkland Islands Dependencies Survey in 1953–54. The name, given in 1956 by the UK Antarctic Place-Names Committee, is descriptive of the red colour of the rocks, madder being a red vegetable pigment.
