Mount Terror is a large shield volcano that forms the eastern part of Ross Island, Antarctica. It has numerous cinder cones and domes on the flanks of the shield and is mostly under snow and ice. It is the second largest of the four volcanoes that make up Ross Island and is somewhat overshadowed by its neighbour, Mount Erebus, 30 km (19 mi) to the west. Mount Terror was named in 1841 by Sir James Clark Ross for his second ship, HMS Terror. The captain of Terror was Francis Crozier, a close friend of Ross for whom the nearby Cape Crozier is named.
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.
James Ross Island is a large island off the southeast side and near the northeastern extremity of the Antarctic Peninsula, from which it is separated by Prince Gustav Channel. Rising to 1,630 metres (5,350 ft), it is irregularly shaped and extends 64 km in a north–south direction. It was charted in October 1903 by the Swedish Antarctic Expedition under Otto Nordenskiöld, who named it for Sir James Clark Ross, the leader of a British expedition to this area in 1842 that discovered and roughly charted a number of points along the eastern side of the island. The style, "James" Ross Island is used to avoid confusion with the more widely known Ross Island in McMurdo Sound.
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 Argentina and South America than any other part of the Antarctic continent.
Hut Point Peninsula is a long, narrow peninsula from 3 to 5 km wide and 24 km (15 mi) long, projecting south-west from the slopes of Mount Erebus on Ross Island, Antarctica. McMurdo Station (US) and Scott Base (NZ) are Antarctic research stations located on the Hut Point Peninsula.
The Saddlestone is a small nunatak, 380 m, standing between Mount Carroll and The Pyramid, in the north part of Tabarin Peninsula in the Antarctic Peninsula. It rises 45 m above the ice sheet at the head of Kenney Glacier. Surveyed in 1955 by Falkland Islands Dependencies Survey (FIDS), who applied the descriptive name; saddlestone is an architectural term for the stone at the apex of a pediment or gable.
Abel Nunatak is the easternmost of two isolated nunataks on the south side of Broad Valley, Trinity Peninsula. It is a volcanic feature and an inferred vent of the James Ross Island Volcanic Group.
Cain Nunatak is the westernmost of two isolated nunataks on the south side of Broad Valley, situated 3.37 km east-northeast of Kumata Hill on Trinity Peninsula, Antarctica. It is a volcanic feature and an inferred vent of the James Ross Island Volcanic Group.
Aitkenhead Glacier is a 10-mile (16 km) long glacier flowing east-southeast from the Detroit Plateau, Graham Land, into Prince Gustav Channel. It was mapped from surveys by the Falkland Islands Dependencies Survey (FIDS) (1960–61), and named by the United Kingdom Antarctic Place-Names Committee for Neil Aitkenhead, a FIDS geologist at Hope Bay (1959–60).
Kienle Nunataks are three aligned nunataks to the north of Mount Terror in northeastern Ross Island, Antarctica. The nunataks trend east–west for 1 nautical mile (2 km) and rise to about 1,700 metres (5,600 ft). The central nunatak is 2.5 nautical miles (5 km) north-northeast of the Mount Terror summit. At the suggestion of P.R. Kyle, they were named by the Advisory Committee on Antarctic Names after Juergen Kienle of the Geophysical Institute, University of Alaska Fairbanks, a United States Antarctic Program team leader for the investigation of volcanic activity and seismicity on Mount Erebus in six field seasons, 1980–81 through 1985–86.
Andersson Nunatak is a nunatak 1 nautical mile (2 km) west of Sheppard Point, standing above the coastal ice cliffs on the north shore of Hope Bay, at the northeast end of the Antarctic Peninsula. It was discovered by Johan Gunnar Andersson's party of the Swedish Antarctic Expedition which wintered at Hope Bay in 1903, and was named for Andersson by the Falkland Islands Dependencies Survey following their survey of the area in 1945.
The Boulder Cones are volcanic cones 0.9 nautical miles (1.7 km) southwest of Castle Rock on Hut Point Peninsula, Ross Island, Antarctica. The name, which is descriptive, was given by Frank Debenham of the British Antarctic Expedition, 1910–13, who made a plane table survey of the peninsula in 1912.
Buttress Hill is a flat-topped hill, 690 metres (2,260 ft) high, with steep rock cliffs on the west side, standing 2 nautical miles (4 km) east of the most northern of the Seven Buttresses on Tabarin Peninsula in the northeastern extremity of the Antarctic Peninsula. It is an inferred volcanic vent of the James Ross Island Volcanic Group and was charted in 1946 by the Falkland Islands Dependencies Survey, so named because of its proximity to the Seven Buttresses.
Vortex Island is an island 0.5 nautical miles (0.9 km) long and 245 m high, lying in the northeast part of Prince Gustav Channel about 2 nautical miles (3.7 km) west-southwest of Corry Island, close south of Trinity Peninsula. Islands in this area were first seen by a party under J. Gunnar Andersson of the Swedish Antarctic Expedition, 1901–04. Vortex Island was first charted by the Falkland Islands Dependencies Survey (FIDS) in August 1945. The FIDS survey party was forced to lie idle there by a whirlwind snowstorm, thus suggesting the name.
Dobson Dome is a prominent snow-covered, dome-shaped mountain 950 metres (3,120 ft) high between Rohss Bay and Croft Bay, in the northern portion of James Ross Island. It was surveyed by the Falkland Islands Dependencies Survey of 1958–61, and it was named by the UK Antarctic Place-Names Committee for Alban Dobson (1885–1962), a British civil servant who was Secretary of the International Whaling Commission from 1949–59 and President of the International Council for the Exploration of the Sea from 1952–55.
Gamma Hill is a distinctive ice-covered hill on Tabarin Peninsula, Antarctica, rising more than 300 metres (980 ft) on the shore of Fridtjof Sound. It is an inferred volcanic vent of the James Ross Island Volcanic Group.
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.
The Tongue Rocks are a small set of ice-free volcanic rocks lying between Eagle Island and Beak Island, off Trinity Peninsula, Antarctica. They are part of the James Ross Island Volcanic Group and were named by United Kingdom Antarctic Place-Names Committee (UK-APC) in association with Eagle and Beak Islands.
Kenney Glacier is a glacier 1 nmi long flowing northwest from The Pyramid and The Saddlestone into Depot Glacier, near the head of Hope Bay, Trinity Peninsula, Antarctica. It was mapped in 1945 and 1948 by the Falkland Islands Dependencies Survey (FIDS), was resurveyed by the FIDS in 1955, and was named for Richard Kenney, assistant surveyor at Hope Bay in 1954 and 1955, who made a detailed local survey of the area between Hope Bay and Duse Bay.
