Posadowsky Glacier is a glacier about 9 nautical miles long, flowing north to Posadowsky Bay immediately east of Gaussberg. Posadowsky Bay is an open embayment, located just east of the West Ice Shelf and fronting on the Davis Sea in Kaiser Wilhelm II Land. Kaiser Wilhelm II Land is the part of East Antarctica lying between Cape Penck, at 87°43'E, and Cape Filchner, at 91°54'E, and is claimed by Australia as part of the Australian Antarctic Territory. Other notable geographic features in this area include Drygalski Island, located 45 mi NNE of Cape Filchner in the Davis Sea, and Mirny Station, a Russian scientific research station.
Deadmond Glacier is a glacier about 6 nautical miles (11 km) long, flowing from the east side of Evans Peninsula on Thurston Island into Cadwalader Inlet. It was discovered by the U.S. Navy Bellingshausen Sea Expedition in February 1960, and was named by the Advisory Committee on Antarctic Names for Lieutenant Commander Robert B. Deadmond, executive officer of USS Burton Island, forming part of this expedition.
Dufayel Island is an island lying near the center of Ezcurra Inlet, Admiralty Bay, in the South Shetland Islands. It was charted and named in December 1909 by the French Antarctic Expedition under Jean-Baptiste Charcot.
Foley Glacier is a glacier about 4 nautical miles (7 km) long flowing north from the western end of Thurston Island just east of Cape Petersen. It was named by the Advisory Committee on Antarctic Names after Kevin M. Foley, of the United States Geological Survey, Reston, Virginia, a computer specialist and team member of the Glaciological and Coastal-Change Maps of Antarctica Project.
Gibbs Glacier is a glacier, 15 nautical miles (28 km) long, flowing southeast into the northern part of Mercator Ice Piedmont on the east side of the Antarctic Peninsula. This feature together with Neny Glacier, which flows northwest, occupy a transverse depression between Mercator Ice Piedmont and Neny Fjord on the west side of the Antarctic Peninsula. Gibbs Glacier was photographed from the air and first mapped by the United States Antarctic Service, 1939–41, and the Ronne Antarctic Research Expedition, 1947–48. It was named by the UK Antarctic Place-Names Committee for Peter M. Gibbs of the Falkland Islands Dependencies Survey, a surveyor at Horseshoe Island, 1957, and leader at Stonington Island, 1958, who was responsible for the first ground survey of the glacier.
Gnomon Island is a small rocky island lying just north of Point Wild, on Elephant Island in the South Shetland Islands. It was charted by Ernest Shackleton's Endurance expedition, 1914–16, and so named by them because when viewed from Point Wild the shape of the feature is suggestive of a gnomon, the elevated arm of a sundial.
Goff Glacier is a broad glacier flowing from Parker Peak into the head of Koether Inlet on the north side of Thurston Island, Antarctica. It was named by the Advisory Committee on Antarctic Names after Lieutenant Robert G. Goff, co-pilot of PBM Mariner aircraft in the Eastern Group of U.S. Navy Operation Highjump, which obtained aerial photographs of Thurston Island and adjacent coastal areas, 1946–47.
Long Glacier is a glacier about 8 nautical miles long in the southeastern part of Thurston Island, Antarctica. It flows south to the Abbot Ice Shelf, 14 nautical miles (26 km) west of Harrison Nunatak. The glacier was mapped by the United States Geological Survey from surveys and U.S. Navy air photos, 1960–66, and was named by the Advisory Committee on Antarctic Names (US-ACAN) for Fred A. Long, Jr., an aviation machinist of U.S. Navy Squadron VX-6, who wintered at Little America V in 1957 and was in Antarctica in the 1960–61 and 1962–63 seasons.
Mincer Glacier is a broad glacier flowing from Zuhn Bluff into the southeast arm of Murphy Inlet on the north side of Thurston Island, Antarctica. It was named by the Advisory Committee on Antarctic Names after Lieutenant Dale F. Mincer, a co-pilot of PBM Mariner aircraft in the Eastern Group of U.S. Navy Operation Highjump, which obtained aerial photographs of Thurston Island and adjacent coastal areas in 1946–47.
Litz Glacier is a glacier flowing northeast from the vicinity of Smith Peak and Litz Bluff in north-central Thurston Island, Antarctica. The glacier enters the west part of Peale Inlet north of the Guy Peaks. It was named by the Advisory Committee on Antarctic Names after A.K. Litz, Chief Photographer's Mate in the Eastern Group of Operation Highjump, which obtained aerial photographs of this glacier and adjacent coastal areas, 1946–47.
Mahaffey Glacier is a glacier flowing into the head of Morgan Inlet at the east end of Thurston Island, Antarctica. It was named by the Advisory Committee on Antarctic Names after J.S. Mahaffey, a Photographer's Mate in the Eastern Group of U.S. Navy Operation Highjump, which obtained aerial photographs of Thurston Island and adjacent coastal areas in 1946–47.
Marck Glacier is a glacier flowing into the southwestern extremity of Cadwalader Inlet on the north side of Thurston Island, Antarctica. It was named by the Advisory Committee on Antarctic Names after Aviation Machinist's Mate George H. Marck, an aircrewman in the Eastern Group of U.S. Navy Operation Highjump, which obtained aerial photographs of Thurston Island and adjacent coastal areas in the summer of 1946–47.
Levko Glacier is a glacier flowing from Pallid Crest to the eastern end of Thurston Island, Antarctica. It enters Seraph Bay between Tierney Peninsula and Simpson Bluff. The glacier was named by the Advisory Committee on Antarctic Names after G. Levko, Photographer's Mate in the Eastern Group of U.S. Navy Operation Highjump, which obtained aerial photographs of Thurston Island and adjacent coastal areas, 1946–47.
