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.
Morainic drift is the movement of rock debris (talus) left by glaciers.
Bunger Hills, also known as Bunger Lakes or Bunger Oasis, is a coastal range on the Knox Coast in Wilkes Land in Antarctica, consisting of a group of moderately low, rounded coastal hills, overlain by morainic drift and notably ice free throughout the year, lying south of the Highjump Archipelago. The reasoning behind the minute amount of ice in the area is still relatively unknown and remains under intense debate amongst scientists today.
Antarctica is Earth's southernmost continent. It contains the geographic South Pole and is situated in the Antarctic region of the Southern Hemisphere, almost entirely south of the Antarctic Circle, and is surrounded by the Southern Ocean. At 14,000,000 square kilometres, it is the fifth-largest continent. For comparison, Antarctica is nearly twice the size of Australia. About 98% of Antarctica is covered by ice that averages 1.9 km in thickness, which extends to all but the northernmost reaches of the Antarctic Peninsula.
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.
Shackleton Ice Shelf is an extensive ice shelf fronting the coast of East Antarctica for about 384 km, projecting seaward about 145 km in the western portion and 64 km in the east. It occupies an area of 33,820 km². 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. The existence of this ice shelf was first made known by the USEE under Charles Wilkes who mapped a portion of it from the Vincennes in February 1840. It was explored by the Australian Antarctic Expedition under Douglas Mawson (1911–14) who named it for Sir Ernest Shackleton. The extent of the ice shelf was mapped in greater detail in 1955, using aerial photography obtained by US Navy Operation Highjump, 1946-47. Further mapping by the Soviet Expedition of 1956 showed the portion eastward of Scott Glacier to be a part of this ice shelf.
Queen Mary Land or the Queen Mary Coast is the portion of the coast of Antarctica lying between Cape Filchner, in 91° 54' E, and Cape Hordern, at 100° 30' E. It is claimed by Australia as part of the Australian Antarctic Territory. It was discovered in February 1912 by the Australasian Antarctic Expedition (1911-14) under the leadership of Douglas Mawson, who named it for Mary of Teck, queen consort of George V.
David Island is an ice-covered island, 10 miles (16 km) long and 6 miles (10 km) wide, marked by rock exposures along its north and east sides, lying off Davis Peninsula in the Shackleton Ice Shelf in Antarctica. It was discovered in November 1912 by the Western Base party of the Australasian Antarctic Expedition (AAE) under Mawson, and named by him for Professor Sir T.W. David Hunt, a member of the AAE Advisory Committee.
The Western Base Party was a successful exploration party of the Australasian Antarctic Expedition. The eight-man Western Party was deposited by the Aurora on the Shackleton Ice Shelf at Queen Mary Land. The leader of the team was Frank Wild and the party included the geologist Charles Hoadley.
The Gillies Islands are three small, rocky islands protruding above Shackleton Ice Shelf 3 nautical miles (6 km) north of Cape Moyes.
Posadowsky Glacier is a glacier about 9 nautical miles long, flowing north to Posadowsky Bay immediately east of Gaussberg.

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.
Wohlschlag Bay is a large bay indenting the west side of Ross Island between Harrison Bluff and Cape Royds. Charted by the Discovery Expedition under Scott, 1901-04. Named by the Advisory Committee on Antarctic Names (US-ACAN) in 1964 for Donald E. Wohlschlag, professor of biology at Stanford University, who outfitted the biology laboratories on the USNS Eltanin and at McMurdo Station, where he worked five summer seasons from 1958-64.
Cape Charcot is a rocky headland at the northeast end of the Melba Peninsula, 3 nautical miles (6 km) west of David Island. It was discovered by the Australasian Antarctic Expedition under Mawson, 1911–14, who named it for Dr. Jean-Baptiste Charcot, French Antarctic explorer.
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.

It was discovered by the Western Base Party of the Australasian Antarctic Expedition under Mawson, 1911–14, who so named it because of its hippo-like shape.
Cape Hunter is a rocky promontory on the west shore of Commonwealth Bay, Antarctica, 8 nautical miles (15 km) west of Cape Denison. It was discovered in 1912 and explored the following year by the Australasian Antarctic Expedition under Douglas Mawson, who named it for John G. Hunter, chief biologist of the expedition.

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.
The United States Geological Survey is a scientific agency of the United States government. The scientists of the USGS study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The organization has four major science disciplines, concerning biology, geography, geology, and hydrology. The USGS is a fact-finding research organization with no regulatory responsibility.
The Geographic Names Information System (GNIS) is a database that contains name and locative information about more than two million physical and cultural features located throughout the United States of America and its territories. It is a type of gazetteer. GNIS was developed by the United States Geological Survey in cooperation with the United States Board on Geographic Names (BGN) to promote the standardization of feature names.
A geographic coordinate system is a coordinate system that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are often chosen such that one of the numbers represents a vertical position and two or three of the numbers represent a horizontal position; alternatively, a geographic position may be expressed in a combined three-dimensional Cartesian vector. A common choice of coordinates is latitude, longitude and elevation. To specify a location on a plane requires a map projection.
