context_page_description: Thatcher Peninsula is a mountainous peninsula in north-central South Georgia. Its total area is approximately 5,640 hectares, with roughly 1,620 ha covered in vegetation. It erminates to the north in Mai Point, rising between Cumberland West Bay to the west, and Cumberland East Bay and Moraine Fjord to the east. It is bounded to the southwest and south by Lyell Glacier and Hamberg Glacier. King Edward Cove on the east side of the peninsula is the site of the British Antarctic Survey Grytviken station and the disused whaling station of the same name.
  Thatcher Peninsula was named by the United Kingdom Antarctic Place-Names Committee in 1991, at the suggestion of members of the Royal Geographical Society, after Margaret Thatcher, British prime minister, 1979–90. She was described by Sir Vivian Fuchs, chair of the Foreign Office's Antarctic Place Names Committee, as 'a major figure in the history of South Georgia', for her role in the Falklands War. Thatcher was, according to friends, "flattered and amused" by the honour.
context_section_description: Lancetes Lake has a rich benthic flora of algae and mosses, which support a large population of the only water beetle seen in the sub-Antarctic, Lancetes clausii, from which the feature takes its name.
  Brown rats are considered an invasive species on Thatcher Peninsula. They threaten the survival of native species such as the South Georgia pipit. From approximately 2011 to 2014, the government of South Georgia and the South Sandwich Islands undertook efforts to eradicate them by air-dropping brodifacoum pellets. Follow-up monitoring a year after the project indicated that the eradication had been a success, with little evidence of rats found.
