evidence: South Georgia, mountainous barren island in the South Atlantic Ocean, 800 miles (1,300 km) east-southeast of the Falkland Islands (Islas Malvinas). It is part of the British overseas territory of South Georgia and the South Sandwich Islands, although Argentina also claims the territory. [...] Britain began establishing research stations on the island in 1945, but it was not until 1964–65 that further explorations of the island’s interior were made, including the first ascent of Mount Paget. The island was the site of military occupation as part of Argentina’s unsuccessful attempt to annex the Falkland Islands and their dependencies during the Falkland Islands War in 1982. A British garrison was established on the island after the war but was decommissioned in 2001. South Georgia and the South Sandwich Islands became a British overseas territory in 1985. A commissioner, who is also the governor of the Falkland Islands, oversees the territory. In 1993 Britain extended the territory’s exclusive fishing zone from 12 to 200 nautical miles (22 to 370 km). Cruise ships make regular visits to the island. The South Georgia Museum, located in the former home of a whaling-station manager, was established in 1992 and has exhibits on whaling, maritime and natural history, and Shackleton memorabilia, among other themes.
