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.
Lofgren Peninsula is an ice-covered peninsula about 22 nautical miles (40 km) long, projecting between Cadwalader Inlet and Morgan Inlet on the northeast side of Thurston Island, Antarctica. The northern extremity of the peninsula is Cape Menzel, a bold rock cape. These features were discovered in helicopter flights from the USS Burton Island and the USS Glacier of the U.S. Navy Bellingshausen Sea Expedition in February 1960, and was named by the Advisory Committee on Antarctic Names. The peninsula was named for Charles E. Lofgren, personnel officer with the Byrd Antarctic Expedition, 1928–30. The cape was named for Reinhard W. Menzel, a geomagnetist-seismologist with the Eights Station winter party, 1965.
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.
Liotard Glacier is a channel glacier in Antarctica. It is about 3 nautical miles (6 km) wide and 6 nautical miles (11 km) long, and flows north-northeast from the continental ice, terminating in a small ice tongue about 4 nautical miles (7 km) west of Hélène Island. The glacier was delineated from air photos taken by U.S. Navy Operation Highjump, 1946–47, and was named by the Advisory Committee on Antarctic Names for Andre-Frank Liotard, the leader of the French Antarctic Expedition, 1949–51, whose group completed the initial survey of the coastal features as far westward as this glacier.
McMullin Island is a rocky island, 0.6 kilometres (0.3 nmi) long, lying between Shirley Island and Kilby Island in the south part of the entrance to Newcomb Bay, in the Windmill Islands, Antarctica.
Hélène Island is a small rocky island 370 metres (0.2 nmi) northwest of Ifo Island marking the west end of the Géologie Archipelago in Antarctica. It was photographed from the air by U.S. Navy Operation Highjump, 1946–47, was charted by the French Antarctic Expedition, 1949–51, and named by them for one of the expedition's dogs.
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.
Manchot Island is a rocky island lying in the entrance to Port Martin, Antarctica. It is 0.4 kilometres (0.2 nmi) west of Bizeux Rock and 0.4 kilometres (0.2 nmi) north of Cape Margerie. The island was photographed from the air by U.S. Navy Operation Highjump, 1946–47, and was charted by the French Antarctic Expedition, 1949–51. It was so named by the French expedition because a large Adélie penguin rookery was located on the island, and "manchot" is a French word for penguin.
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.
The Triple Islands are three small rocky islands lying close east of the tip of Zélée Glacier Tongue and 0.7 kilometres (0.4 nmi) south-southeast of the Double Islands. They were photographed from the air by U.S. Navy Operation Highjump, 1946–47, and were charted and named by the French Antarctic Expedition, 1949–51.
