Thurston Island is an ice-covered, glacially dissected island, 215 km (134 mi) long, 90 km (56 mi) wide and 15,700 km2 (6,062 sq mi) in area, lying a short way off the northwest end of Ellsworth Land, Antarctica. It is the third largest island of Antarctica, after Alexander Island and Berkner Island.
Alexandra Mountains is a group of low, separated mountains in the north portion of Edward VII Peninsula, just southwest of Sulzberger Bay in Marie Byrd Land, Antarctica. Discovered in January–February 1902 by the British National Antarctic Expedition during an exploratory cruise of the Discovery along the Ross Ice Shelf. Named for Alexandra, then Queen of the United Kingdom.
Little America was a series of Antarctic exploration bases from 1929 to 1958, located on the Ross Ice Shelf, south of the Bay of Whales.
Vincennes Bay is a large V-shaped bay, 105 km (65 mi) wide at its entrance between Cape Nutt and Cape Folger in Antarctica, marked by several large, steep glaciers near its head, lying along Knox and Budd Coasts. It was photographed from the air by US Navy Operation Highjump in 1946–47. The bay was entered in January 1948 by US Navy Operation Windmill icebreakers Burton Island and stations in the Windmill Islands in the NE portion of the bay. Named by the US-ACAN for the sloop of war USS Vincennes, flagship of the USEE under Wilkes, from which a series of coastal landfalls along Wilkes Land were discovered and plotted during January–February 1840. Wilkes' chart suggests a possible coastal recession corresponding closely with the longitudinal limits for Vincennes Bay, although pack ice conditions prevented close reconnaissance by the USEE of the coast in this immediate area.
The Byrd Glacier is a major glacier in Antarctica, about 136 km (85 mi) long and 24 km (15 mi) wide, draining an extensive area of the polar plateau and flowing eastward between the Britannia Range and Churchill Mountains to discharge into the Ross Ice Shelf at Barne Inlet. Its valley below the glacier used to be recognised as one of the lowest points not to be covered by water on Earth, reaching 2,780 metres below sea level. It was named by the NZ-APC after Rear Admiral Byrd, US Navy Antarctic explorer.
Bear Peninsula is a peninsula about 80 km (50 mi) long and 40 km (25 mi) wide which is ice covered except for several isolated rock bluffs and outcrops along its margins, lying 48 km 30 mi) east of Martin Peninsula on Walgreen Coast, Marie Byrd Land, Antarctica.
Shackleton Ice Shelf is an extensive ice shelf fronting the coast of East Antarctica from 95° E to 105° E. It extends for an along-shore distance of about 384 kilometres (239 mi), projecting seaward about 145 kilometres (90 mi) in the western portion and 64 kilometres (40 mi) in the east. It occupies an area of 33,820 square kilometres (13,058 sq mi). It is part of Mawson Sea and separates the Queen Mary Coast to the west from the Knox Coast of Wilkes Land to the east.
Lambert Glacier is a major glacier in East Antarctica. At about 50 miles (80 km) wide, over 250 miles (400 km) long, and about 2,500 m deep, it holds the Guinness world record for the world's largest glacier. It drains 8% of the Antarctic ice sheet to the east and south of the Prince Charles Mountains and flows northward to the Amery Ice Shelf. It flows in part of Lambert Graben and exits the continent at Prydz Bay.
The Vestfold Hills are rounded, rocky, coastal hills, 411 square kilometres (159 sq mi) in extent, on the north side of Sorsdal Glacier on the Ingrid Christensen Coast of Princess Elizabeth Land, Antarctica. The hills are subdivided by three west-trending peninsulas bounded by narrow fjords. Most of the hills range between 30 and 90 metres in height, with the highest summit reaching nearly 160 metres (520 ft).
Cape Hordern is an ice-free cape, overlain by morainic drift, at the northwest end of the Bunger Hills in Antarctica. It was probably sighted from Watson Bluff by A.L. Kennedy and other members of the Western Base Party of the Australasian Antarctic Expedition under Mawson, 1911–14, who charted the west wall of what appeared to be two small islands lying north of Cape Hoadley in about 100°35′E. It was named "Hordern Island" by Mawson for Sir Samuel Hordern of Sydney, a patron of the expedition. It was renamed Cape Hordern by the Advisory Committee on Antarctic Names (US-ACAN) following correlation of Kennedy's map with the US-ACAN map of 1955 compiled from aerial photographs taken by U.S. Navy Operation Highjump, 1946–47.
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.
Algae Lake is a narrow, winding lake, 9 nautical miles (17 km) long and between 0.2 and 1 nautical mile wide, extending in an east–west direction in the ice-free Bunger Hills of Antarctica. It was first mapped from air photos taken by U.S. Navy Operation Highjump, 1946–47, and named "Algae Inlet" by the Advisory Committee on Antarctic Names because of the algae reported by Operation Highjump personnel, which cause varying tints to the meltwater ponds overlying the Bunger Hills and to the saline inlets and channels in the Highjump Archipelago area close to the north. Subsequent Soviet Antarctic Expeditions (1956–57) found this "inlet" to be a lake.
Apfel Glacier is a glacier about 5 nautical miles (10 km) wide and 20 nautical miles (40 km) long, flowing west-northwest along the south flank of the Bunger Hills and terminating in Edisto Ice Tongue. It was mapped from air photos taken by U.S. Navy Operation Highjump, 1946–47, and named by the Advisory Committee on Antarctic Names for Earl T. Apfel, professor of geology at Syracuse University, who served as geologist with the U.S. Navy Operation Windmill parties, 1947–48, which established astronomical control stations along Queen Mary, Knox and Budd Coasts.
Booth Peninsula is a rocky peninsula, 4 nautical miles (7 km) long and 1 nautical mile (2 km) wide, of Antarctica, which projects west from the coast 3 nautical miles (6 km) southwest of Remenchus Glacier. It was mapped from aerial photographs taken by U.S. Navy Operation Highjump, 1946–47, and named by the Advisory Committee on Antarctic Names for George H. Booth, an air crewman on the Operation Highjump seaplane commanded by D.E. Bunger which landed in this area and obtained aerial and ground photographs of this ice-free region.
The Dufek Coast is that portion of the coast along the southwest margin of the Ross Ice Shelf between Airdrop Peak on the east side of the Beardmore Glacier and Morris Peak on the east side of Liv Glacier. It was named by the New Zealand Antarctic Place-Names Committee in 1961 after Rear Admiral George J. Dufek, United States Navy, who served under Rear Admiral Richard E. Byrd with the United States Antarctic Service, 1939–41, and as commander of the Eastern Task Force of U.S. Navy Operation Highjump, 1946–47. He was Commander of U.S. Naval Support Force Antarctica, 1954–59, a period in which the following American science stations were established: McMurdo Station, Little America V, Byrd Station, South Pole Station, Wilkes Station, Hallett Station and Ellsworth Station. United States Navy ships, aircraft, and personnel under his command provided broad logistical support to research and survey operations, including aerial photographic missions to virtually all sectors of Antarctica. On October 31, 1956, Dufek in the ski-equipped R4D Skytrain aircraft Que Sera Sera, flew from McMurdo Sound via Beardmore Glacier to make the first airplane landing at the South Pole.
Edisto Ice Tongue is an ice tongue along the northwest margin of the Bunger Hills where it occupies the southwestern portion of Edisto Channel, in the Highjump Archipelago. The ice tongue is a seaward extension of the flow of Apfel Glacier as well as part of the main flow of Scott Glacier. It was mapped from air photos taken by U.S. Navy Operation Highjump, 1946–47, and was named by the Advisory Committee on Antarctic Names in association with Edisto Channel.
The Highjump Archipelago is a group of rocky islands, rocks and ice rises in Antarctica, about 93 kilometres (50 nmi) long and from 9 to 28 kilometres wide, lying generally north of the Bunger Hills and extending from the Taylor Islands, close northwest of Cape Hordern, to a prominent group of ice rises which terminate close west of Cape Elliott. It was delineated from aerial photographs taken by U.S. Navy Operation Highjump 1946–47 and so named by the Advisory Committee on Antarctic Names. The codeword "highjump" was used for identifying the U.S. Navy Task Force 68, 1946–47. This task force was divided into three groups which completed photographic flights covering approximately 70 per cent of the coastal areas of Antarctica, excluding the Antarctic Peninsula, as well as significant portions of the interior.
Cape Henderson is an ice-free cape, overlain by morainic drift, marking the northwest end of the Bunger Hills in Antarctica. It was mapped from air photos taken by U.S. Navy Operation Highjump in February 1947, and was named by the Advisory Committee on Antarctic Names for the USS Henderson (DD-785), the destroyer escort of the western task group of Operation Highjump, Task Force 68, 1946–47.
Smith Lake is a lake, 1 nautical mile (1.9 km) long, in the Bunger Hills, occupying the east half of the peninsula between Booth and Countess Peninsulas. First mapped from air photos taken by U.S. Navy Operation Highjump, 1946–47. The name "Smith Ridge" was given to the peninsula in 1956 by Advisory Committee on Antarctic Names (US-ACAN) but was later dropped. The lake has instead been named for Kenneth R. Smith, air crewman on the U.S. Navy Operation Highjump seaplane commanded by D.E. Bunger which landed in the area and obtained air and ground photos in February 1947.
A.B. Dobrowolski Polar Station is a occasionally active Polish polar research station in Antarctica. It is located at the edge of the Algae Lake, Bunger Hills region in the Wilkes Land and was originally constructed by the Soviet Union. It is one of the two Polish stations in Antarctica, the other being the Henryk Arctowski Polish Antarctic Station.
