Thatcher Peninsula
South Georgia and the South Sandwich Islands
Thatcher Peninsula (54°17′S 36°32′W) is a mountainous peninsula in north-central South Georgia. Its total area is approximately 5,640 hectares (13,900 acres), with roughly 1,620 ha (4,000 acres) covered in vegetation. It terminates 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 (BAS) Grytviken station and the disused whaling station of the same name.
Thatcher Peninsula was named by the United Kingdom Antarctic Place-Names Committee (UK-APC) 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.
Geography
Many features on the coast of the peninsula have been individually charted and named. Features on the west coast are detailed as part of Cumberland West Bay, and those on the east coast are detailed as part of Cumberland East Bay.
This brief starts where responsible research should: with the source description of “Thatcher Peninsula” as south Georgia and the South Sandwich Islands. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as south Georgia and the South Sandwich Islands. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Dec 18, 2025. The linked authority identifier is Q613738. Authority coordinates are -54.283, -36.533. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1991 and 1979.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
