The Bay of Isles is a bay 9 miles (14 km) wide and receding 3 miles (5 km), lying between Cape Buller and Cape Wilson along the north coast of South Georgia. It was discovered in 1775 by a British expedition under James Cook and so named by him because numerous islands lie in the bay. Of South Georgia's 31 breeding bird species, 17 are found here.
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.

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.
Anthony Glacier is a glacier which flows in an east-southeast direction to the east coast of Palmer Land where it terminates opposite the south tip of Hearst Island. The upper part of this glacier was seen by a sledge party of the British Graham Land Expedition under John Riddoch Rymill in 1936–37. The glacier was seen from the seaward side in 1940 by a sledging party from the East Base of the United States Antarctic Service, and in 1947 was photographed from the air by the Ronne Antarctic Research Expedition (RARE). It was named by Finn Ronne for Alexander Anthony of the J.P. Stevens Company, New York City, which contributed windproof clothing to the RARE.
Balch Glacier is a glacier 9 nautical miles (17 km) long, on the east coast of Graham Land, flowing southeast into Mill Inlet, to the south of Gould Glacier.
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.
Trench Glacier is a deeply entrenched glacier extending along the east coast of Alexander Island, Antarctica, 6 nautical miles (11 km) long and 2 nautical miles (3.7 km) wide, which flows east into the George VI Ice Shelf that occupies George VI Sound immediately south of Mount Athelstan. The mouth of this glacier was first photographed from the air on November 23, 1935, by Lincoln Ellsworth, and it was mapped from these photos by W.L.G. Joerg. Trench Glacier was surveyed in 1948 and 1949 by the Falkland Islands Dependencies Survey, who applied this descriptive name.
Foley Glacier is a glacier about 4 nautical miles (7 km) long flowing north from the western end of Thurston Island just east of Cape Petersen. It was named by the Advisory Committee on Antarctic Names after Kevin M. Foley, of the United States Geological Survey, Reston, Virginia, a computer specialist and team member of the Glaciological and Coastal-Change Maps of Antarctica Project.
Frankenfield Glacier is a small glacier in the northeast part of Noville Peninsula, Thurston Island, in Antarctica. It flows east-northeast to the Bellingshausen Sea between Mount Feury and Mulroy Island. The glacier was first roughly delineated from air photos taken by U.S. Navy Operation Highjump in December 1946, and was named by the Advisory Committee on Antarctic Names for Lieutenant Chester Frankenfield, a meteorologist on the U.S. Navy Bellingshausen Sea Expedition, who established an automated weather station on Thurston Island in February 1960.
Green Glacier is a glacier on the east side of Graham Land, Antarctica, 15 nautical miles (28 km) long and 4 nautical miles (7 km) wide, flowing from the plateau northeast between Dugerjav Peak and Rugate Ridge, and then east into Vaughan Inlet next north of Pirne Peak and south of the terminus of Hektoria Glacier.

Hlubeck Glacier is a glacier 9 nautical miles west of Long Glacier in southeast Thurston Island, Antarctica. It flows south along the east side of Shelton Head into the Abbot Ice Shelf. The glacier was named by the Advisory Committee on Antarctic Names after aviation radioman Vernon R.
