Coronation Island is the largest of the South Orkney Islands, 25 nautical miles (46 km) long and from 3 to 8 nautical miles 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 1,265 metres (4,150 ft).
Denman Glacier is a glacier 7 to 10 nautical miles wide, descending north some 70 nautical miles, which debouches into the Shackleton Ice Shelf east of David Island, Queen Mary Land. It was discovered in November 1912 by the Western Base party of the Australasian Antarctic Expedition under Sir Douglas Mawson. Mawson named the glacier for Lord Denman, Governor-General of Australia in 1911, a patron of the expedition.
Cape Longing is a rocky cape on the east coast of Graham Land, Antarctica, forming the south end of a large ice-covered promontory which marks the west side of the south entrance to Prince Gustav Channel. It was discovered by the Swedish Antarctic Expedition under Otto Nordenskiöld in 1902, and so named by him because from the position of his winter hut on Snow Hill Island the cape lay in the direction of his "land of longing" which he was anxious to explore.
Snow Hill Island is an almost completely snowcapped island, 33 km (21 mi) long and 12 km (7.5 mi) wide, lying off the east coast of the Antarctic Peninsula. It is separated from James Ross Island to the north-east by Admiralty Sound and from Seymour Island to the north by Picnic Passage. It is one of several islands around the peninsula known as Graham Land, which is closer to South America than any other part of the Antarctic continent.
The Eklund Islands are a group of islands which rise through the ice near the southwest end of George VI Sound towards the south of the Antarctic Peninsula.
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.
Clow Island is an island 1.1 kilometres (0.6 nmi) long in the eastern part of Lake Fryxell in Taylor Valley, Victoria Land. This feature was a peninsula as recently as the 1980s when the rising level of the lake submerged the eastern part of the peninsula and created the island. It was named by the Advisory Committee on Antarctic Names (2000) after Gary D. Clow of the United States Geological Survey, who studied sand/ice interactions and sediment deposition in perennially ice-covered lakes in Taylor Valley, 1985–86, and glacier geophysics at Taylor Dome, 1993–94 through 1995–96.
Noville Peninsula is a high ice-covered peninsula about 30 nautical miles (60 km) long, between Peale and Murphy Inlets on the north side of Thurston Island in Antarctica. Delineated from aerial photographs made by U.S. Navy Operation Highjump in December 1946. Named for George O. Noville, executive officer of Byrd Antarctic Expedition, 1933-35.
Dendtler Island is an ice-covered island, 26 kilometres (14 nmi) long, lying in the eastern part of the Abbot Ice Shelf between Farwell Island and Fletcher Peninsula in Antarctica. It 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 for Major Robert Dendtler, United States Army, coordinating officer on the staff of the Commander, U.S. Navy Support Force, Antarctica, during Operation Deep Freeze 1967 and 1968.
Grinder Island is one of the ice-covered islands in the Marshall Archipelago, located within the Sulzberger Ice Shelf off the coast of Marie Byrd Land, Antarctica. The island is 13 kilometres (7 nmi) long and 2 kilometres (1 nmi) wide and lies 24 kilometres (13 nmi) southwest of Steventon Island. It was mapped by the United States Geological Survey from surveys and U.S. Navy air photos, 1959–65, and was named by the Advisory Committee on Antarctic Names for Harry W. Grinder, a U.S. Navy aviation structural mechanic of McMurdo Station, 1967.
Evans Peninsula is an ice-covered peninsula about 30 nautical miles (60 km) long, between Koether Inlet and Cadwalader Inlet in the northeast part of Thurston Island. Cape Braathen is an ice-covered cape at the northwest termination of Evans Peninsula. It was discovered in flights from the USS Burton Island and USS Glacier by personnel of the U.S. Navy Bellingshausen Sea Expedition in February 1960, and was named by the Advisory Committee on Antarctic Names (US-ACAN) for Commander Griffith Evans, Jr., commander of the icebreaker Burton Island during this expedition.
Hale Glacier is a glacier about 6 nautical miles (11 km) long, located just east of Mount Simpson on Thurston Island, Antarctica, and flowing southwest to the Abbot Ice Shelf in Peacock Sound. It was delineated from air photos taken by U.S. Navy Squadron VX-6 in January 1960, and was named by the Advisory Committee on Antarctic Names (US-ACAN) for Lieutenant Bill J. Hale, U.S. Navy, a helicopter pilot aboard USS Burton Island who made exploratory flights to Thurston Island in February 1960.
Hannah Island is an ice-covered island in the Marshall Archipelago, lying between Hutchinson Island and Guest Peninsula within the Sulzberger Ice Shelf, off the coast of Antarctica. It was mapped by the United States Geological Survey from surveys and U.S. Navy air photos (1959–65), and was named by the Advisory Committee on Antarctic Names for J.P. Hannah, a United States Antarctic Research Program ionospheric physicist at Byrd Station in 1968.
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.
McKinnon Island is a large island, mostly ice-covered, in the Hannan Ice Shelf along the coast of Enderby Land, Antarctica. It was plotted from air photos taken by the Australian National Antarctic Research Expeditions in 1956, and was named for Graeme W. McKinnon, Geographical Officer of the Antarctic Division, Melbourne, and Secretary of the Antarctic Names Committee of Australia.
Tierney Peninsula is an ice-covered peninsula about 14 nautical miles (26 km) long, between Savage Glacier and Morgan Inlet in the east end of Thurston Island. The east extremity of the peninsula is Cape Annawan. These features were discovered on helicopter flights from the USS Burton Island and Glacier of the U.S. Navy Bellingshausen Sea Expedition in February 1960 and named by the Advisory Committee on Antarctic Names (US-ACAN). The peninsula was named for J.Q. Tierney, oceanographer aboard the Burton Island on this expedition. The cape was named for the ship Annawan of the United States Expedition of 1829-31, which with the Penguin sailed west from the South Shetland Islands in February 1830, holding a course between 62S and 58S and exploring as far as 103W, northward of this cape.
Langhofer Island is a small ice-covered island with a rock outcrop near the south end, lying at the north edge of the Abbot Ice Shelf, Antarctica, and 1 kilometre (0.5 nmi) east of McNamara Island. The USS Glacier (AGB-4) lay close off the island, February 11, 1961, and geological and botanical collections were made at the outcrop. The island was named by the Advisory Committee on Antarctic Names for Joel H. Langhofer, a United States Geological Survey topographic engineer aboard the Glacier who positioned geographical features in this area.
