Smooth Island is the northeasternmost of the Forge Islands, Argentine Islands, in the Wilhelm Archipelago. The name, given by the United Kingdom Antarctic Place-Names Committee (UK-APC) in 1961, is descriptive of the smooth, ice-free surface of this island, which is a useful navigational mark for vessels approaching Bloor Passage from the north.

The British Antarctic Territory (BAT) is a sector of Antarctica claimed by the United Kingdom as one of its 14 British Overseas Territories, of which it is by far the largest by area. It comprises the region south of 60°S latitude and between longitudes 20°W and 80°W, forming a wedge shape that extends to the South Pole, overlapped by the Antarctic claims of Argentina and Chile.
The South Shetland Islands are a group of Antarctic islands with a total area of 3,687 km2 (1,424 sq mi). They lie about 120 kilometres north of the Antarctic Peninsula, and between 430 and 900 km southwest of the nearest point of the South Orkney Islands. By the Antarctic Treaty of 1959, the islands' sovereignty is neither recognized nor disputed by the signatories and they are free for use by any signatory for non-military purposes.
Alexander Island, which is also known as Alexander I Island, Alexander I Land, Alexander Land, Alexander I Archipelago, and Zemlja Alexandra I, is the largest island of Antarctica. It lies in the Bellingshausen Sea west of Palmer Land, Antarctic Peninsula from which it is separated by Marguerite Bay and George VI Sound. The George VI Ice Shelf entirely fills George VI Sound and connects Alexander Island to Palmer Land. The island partly surrounds Wilkins Sound, which lies to its west. Alexander Island is about 390 kilometres (240 mi) long in a north–south direction, 80 kilometres (50 mi) wide in the north, and 240 kilometres (150 mi) wide in the south. Alexander Island is the second-largest uninhabited island in the world, after Devon Island.
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.
Petermann Island is a small, low and rounded island, lying off the northwest coast of Kyiv Peninsula in Graham Land, Antarctica, a short distance south of Booth Island and the Lemaire Channel. It is a popular tourist destination.
Adelaide Island is a large, mainly ice-covered island, 139 kilometres (75 nmi) long and 37 kilometres (20 nmi) wide, lying at the north side of Marguerite Bay off the west coast of the Antarctic Peninsula. The Ginger Islands lie off the southern end. Mount Bodys is the easternmost mountain on Adelaide Island, rising to over 1,220 m. The island lies within the Argentine, British and Chilean Antarctic claims.
Trinity Island or Île de la Trinité or Isla Trinidad is an island 24 km (15 mi) long and 10 km (6 mi) wide in the northern part of the Palmer Archipelago, Antarctica. It lies 37 km (23 mi) east of Hoseason Island, 72.6 km (45 mi) south of Deception Island in the South Shetland Islands, and 10.3 km (6 mi) north-northwest of Cape Andreas on the Antarctic Peninsula. The island was named by Otto Nordenskiöld, leader of the 1901-1904 Swedish Antarctic Expedition (SAE) in commemoration of Edward Bransfield's "Trinity Land" of 1820.
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.
Cape Evans is a rocky cape on the west side of Ross Island, Antarctica, forming the north side of the entrance to Erebus Bay.
Smyley Island is an Antarctic island lying off the Antarctic Peninsula. The island is 61 km (38 mi) long and from 13 to 34 km wide, and lies about 20 km (12 mi) north of Case Island. It connects to the Stange Ice Shelf and is separated from Alexander Island by the Ronne Entrance. Smyley Island is one of the 27 islands of Palmer Land, Antarctica.
Emperor Island is a small island in Marguerite Bay, lying close north-east of the Courtier Islands in the Dion Islands. The islands in this group were discovered and roughly charted in 1909 by the French Antarctic Expedition. This island was surveyed in 1948 by the Falkland Islands Dependencies Survey and so named by the UK Antarctic Place-Names Committee because a low rock and shingle isthmus at the south-eastern end of the island was the winter breeding site of emperor penguins.
Endurance Glacier is a broad glacier north of Mount Elder, draining south-east to the south coast of Elephant Island in the South Shetland Islands of Antarctica, and is the main discharge glacier on the island. It was named by the UK Antarctic Place-Names Committee after HMS Endurance, which anchored off the glacier on several occasions in support of the Joint Services Expedition to Elephant Island, 1970–71.
Compton Glacier is a glacier, 3 nautical miles (6 km) long, flowing northeast from the lower slopes of the Big Ben massif to the northeast side of Heard Island in the southern Indian Ocean. Its terminus is located at Compton Lagoon, between Gilchrist Beach and Fairchild Beach. To the northwest of Compton Glacier is Ealey Glacier, whose terminus is located close southeast of Cape Bidlingmaier. To the southeast of Compton Glacier is Brown Glacier, whose terminus is located at Brown Lagoon. Round Hill separates Compton Glacier from Brown Glacier. Since the ANARE survey of 1947/48, the glacier has retreated significantly, exposing much more of Compton Lagoon. Evidence for significant loss was recorded as early as 1963, with an expedition describing the glacier as no longer smooth, but crevassed. By the late 1970s it had retreated 1.6 km and by the time of a 1987 survey, it was 2.5 km inland from its 1947 front.
Bellisime Glacier is a glacier about 4 nautical miles (7 km) long flowing south from Thurston Island east of Myers Glacier. It was named by the Advisory Committee on Antarctic Names after Lynda B. Bellisime of the United States Geological Survey (USGS), Flagstaff, Arizona, part of the USGS team that compiled the 1:5,000,000-scale Advanced Very High Resolution Radiometer maps of Antarctica and the 1:250,000-scale Landsat TM image maps of the Siple Coast area in the 1990s.
Deadmond Glacier is a glacier about 6 nautical miles (11 km) long, flowing from the east side of Evans Peninsula on Thurston Island into Cadwalader Inlet. It was discovered by the U.S. Navy Bellingshausen Sea Expedition in February 1960, and was named by the Advisory Committee on Antarctic Names for Lieutenant Commander Robert B. Deadmond, executive officer of USS Burton Island, forming part of this expedition.
Exodus Glacier is a steep, smooth glacier 1 nautical mile (2 km) northeast of Mount Ellis, flowing from the northern edge of Midnight Plateau to the southwest side of Island Arena, in the Darwin Mountains of Antarctica. It was named by the Victoria University of Wellington Antarctic Expedition, 1962–63, in association with nearby Exodus Valley.
Moe Island is an island 2 km (1.2 mi) long in the South Orkney Islands off Antarctica, separated from the south-west end of Signy Island by Fyr Channel. It was charted by Captain Petter Sørlle in 1912–13, and named after M. Thoralf Moe of Sandefjord, Norway, a contemporary whaling captain who worked in this area. The northernmost point of the island is Spaull Point, named by United Kingdom Antarctic Place-Names Committee (UK-APC) after Vaughan W. Spaull, British Antarctic Survey (BAS) biologist on Signy Island, 1969.
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.
Lofty Promenade is an inclined glacial course, 7 nautical miles (13 km) long and 1 nautical mile (2 km) wide, in the eastern part of Ross Island, Antarctica. The feature is partly framed between the southern elements of the Kyle Hills and Guardrail Ridge, as it descends east-southeast from 2,600 metres (8,500 ft) near Mount Terror to 200 metres (660 ft) near the Allen Rocks. The glacial surface is relatively smooth and affords an unobstructed route between the Cape Crozier area and Mount Terror. The name, given by the Advisory Committee on Antarctic Names in 2000, is allusive and refers to a public place for taking a leisurely walk.
Levko Glacier is a glacier flowing from Pallid Crest to the eastern end of Thurston Island, Antarctica. It enters Seraph Bay between Tierney Peninsula and Simpson Bluff. The glacier was named by the Advisory Committee on Antarctic Names after G. Levko, Photographer's Mate in the Eastern Group of U.S. Navy Operation Highjump, which obtained aerial photographs of Thurston Island and adjacent coastal areas, 1946–47.
