Half Moon Beach is a small crescent-shaped beach lying south-east of Scarborough Castle on the north coast of Livingston Island, in the South Shetland Islands of Antarctica. The beach lieas at the western extremity of Porlier Bay in the north of Ioannes Paulus II Peninsula. History The descriptive name was recorded by Robert Fildes, who had sealers working here in 1820–21 and 1821–22. Wreckage of the Spanish ship San Telmo that sank off the island in 1819 was subsequently found on the beach. Historic site A cairn at the beach, along with a plaque on ‘Cerro Gaviota’ opposite San Telmo Island, commemorates the officers, soldiers and seamen aboard the San Telmo, who were possibly the first people to live and die in Antarctica. It has been designated a Historic Site or Monument San Telmo Cairn (HSM 59), following a proposal by Chile, Spain and Peru to the Antarctic Treaty Consultative Meeting. Maps L.L. Ivanov et al.
