Another Antarctic explorer with a special place in South Georgia's history was Duncan Carse. His comprehensive 1951–57 South Georgia Survey resulted in the classical 1:200000 topographic map of South Georgia, occasionally updated but never superseded since its first publication by the British Directorate of Overseas Surveys in 1958. For several months in 1961, Carse experimented on living alone at a remote location, Ducloz Head on the southwest coast of the island. Mount Carse, the island's third highest peak is named for him.
