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.
The Antarctic Sound is a body of water about 30 nautical miles long and from 7 to 12 nautical miles wide, separating the Joinville Island group from the northeast end of the Antarctic Peninsula. The sound was named by the Swedish Antarctic Expedition under Otto Nordenskjöld for the expedition ship Antarctic which in 1902, under the command of Carl Anton Larsen, was the first vessel to navigate it. Since 2005 cruise ships have been visiting the area.
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.
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.
Cape Flying Fish is an ice-covered cape which forms the western extremity of Thurston Island. It was discovered by Rear Admiral Richard E. Byrd and members of the US Antarctic Service in a flight from the Bear in February 1940. It was named by the Advisory Committee on Antarctic Names for the United States Exploring Expedition ship Flying Fish, commanded by Lieutenant William M. Walker, U.S. Navy, which reached a point within 125 miles of this cape; the ship's position on the morning of March 23, 1839 was 70°0′S100°16′W.
Wilson Hills is a group of scattered hills, nunataks and ridges that extend NW-SE for about 110 kilometres (68 mi) between Matusevich Glacier and Pryor Glacier in Antarctica. They were discovered by Lieutenant Harry Pennell, Royal Navy, on the Terra Nova Expedition in February 1911 during Robert Falcon Scott's last expedition, and named after Dr. Edward A. Wilson, a zoologist with the expedition, who perished with Scott on the return journey from the South Pole.
Siffrey Point is a low rocky point projecting from the north coast of Trinity Peninsula, Antarctica situated 6.7 miles (11 km) west-northwest of Cape Dubouzet, 2.5 miles (4 km) east-southeast of Prime Head and 5.4 miles (9 km) northwest of Mount Bransfield. The feature is a reidentification of "Cap Siffrey," named by Captain Jules Dumont d'Urville in 1838.
Azufre Point is a headland lying 3 miles (5 km) southeast of Cape Renard on the south side of Flandres Bay, on the west coast of Graham Land. It was first charted by the Belgian Antarctic Expedition under Adrien de Gerlache, 1897–99, and later charted by the Argentine Antarctic Expedition (1954) and named "Punta Azufre".
Tabarin Peninsula is a peninsula 15 nautical miles (28 km) long and 5 to 12 nautical miles (22 km) wide, lying south of the trough between Hope Bay and Duse Bay and forming the east extremity of Trinity Peninsula in the Antarctic Peninsula. It was discovered and charted by the Swedish Antarctic Expedition, 1901–1904, led by Otto Nordenskjöld and Carl Anton Larsen. It was mapped in 1946 by the Falkland Islands Dependencies Survey (FIDS) and named after Operation Tabarin, the naval code name for the FIDS from 1943 to 1945.
Arena Glacier is a glacier 3 nautical miles (6 km) long, flowing northeast from Mount Taylor into Hope Bay 2 nautical miles (4 km) southwest of Sheppard Point, at the extremity of the Trinity Peninsula. It was mapped in 1948 and 1955 by the Falkland Islands Dependencies Survey and so named by them because the flat ice floor of the glacier's upper half, surrounded by the steep slopes of Twin Peaks, Mount Taylor and Blade Ridge, resembles an arena.
Mount Bransfield is a prominent conical-topped, ice-covered mountain, 760 metres (2,500 ft) high, rising 5.4 miles (9 km) east-southeast of Siffrey Point, 2 nautical miles (4 km) southwest of Cape Dubouzet and 2.7 nautical miles (5 km) north of Koerner Rock, at the northeast tip of the Antarctic Peninsula.
Corner Peak is a pyramidal peak, 930 metres (3,050 ft) high, with considerable rock exposed on its northern face. Located in the northeastern Srednogorie Heights, 8 nautical miles (15 km) east-southeast of Cape Roquemaurel, it marks a corner in the broad glacial valley of Malorad Glacier which rises immediately to the southeast and fans out northwest to form a piedmont ice sheet on the northwest side of the Trinity Peninsula. It was named by the Falkland Islands Dependencies Survey following a 1946 survey.
Koerner Rock is a small but conspicuous rock outcropping located 4 nautical miles (7 km) southwest of Cape Dubouzet and 2.08 nautical miles (4 km) southeast of Yagodina Knoll, Trinity Peninsula, Antarctica. It was named by the UK Antarctic Place-Names Committee for Roy M. Koerner, an assistant meteorologist and glaciologist with the Falkland Islands Dependencies Survey at Hope Bay, from 1957 to 1960.
Depot Glacier is a well-defined valley glacier, flanked by lateral moraines, which terminates in a high vertical ice cliff at the head of Hope Bay, in the northeast end of the Antarctic Peninsula. It was discovered by the Swedish Antarctic Expedition, 1901–04, under Otto Nordenskiöld, and so named by him because, as seen from Antarctic Sound, it appeared to be a possible site for a depot.
Duclaux Point is a point extending into Bouquet Bay from the east side of Pasteur Peninsula, 3 nautical miles (6 km) southeast of Cape Cockburn on Brabant Island in the Palmer Archipelago. It was first charted by the French Antarctic Expedition, 1903–05, and named by Jean-Baptiste Charcot for Pierre E. Duclaux, a French biochemist who was director of the Pasteur Institute in Paris in 1895.
Cape Gordon is a jagged headland 330 metres (1,080 ft) high, forming the east end of Vega Island, lying south of the northeast tip of the Antarctic Peninsula. It was discovered by a British expedition 1839–43, under James Clark Ross, and named by him for Captain William Gordon, Royal Navy, a Lord Commissioner of the Admiralty.
Mineral Hill is a round-topped hill, 445 metres (1,460 ft) high, with ice-free, talus-covered slopes, standing 1.5 nautical miles (3 km) west of Trepassey Bay on Tabarin Peninsula, Antarctica. It was probably first seen by the Swedish Antarctic Expedition under Otto Nordenskiöld, 1901–04. The hill was first charted by the Falkland Islands Dependencies Survey in 1946, who so named it because small quantities of reddish mineral in the rock gave the surfaces a conspicuous color.
McCalman Peak is the 550-metre (1,800 ft) summit of an east–west trending ridge 3 nautical miles (6 km) north of Crystal Hill, 3.97 km east-northeast of Gornik Knoll, 6.9 km south-southeast of Kumata Hill and 4.55 km west-southwest of Zaldapa Ridge on Trinity Peninsula, Antarctica. It was named by the UK Antarctic Place-Names Committee for Donald McCalman, a surveyor with the Falkland Islands Dependencies Survey at Hope Bay in 1958–59.
The Steeple is a rocky ridge, about 500 m, forming the northwest arm of horseshoe-shaped Mount Carroll. It rises on the east side of Depot Glacier, 1.5 nautical miles (2.8 km) south of the head of Hope Bay, at the northeast end of Antarctic Peninsula. Discovered by the Swedish Antarctic Expedition, 1901–04, under Otto Nordenskjöld. The descriptive name was applied by the Falkland Islands Dependencies Survey (FIDS), 1945.
