(Deception Island)

British Antarctic Territory

Location: 62° 57' S 60° W
drowned and breached volcanic crater forming harbour of Deception Island, was discovered by Palmer, 15 November 1820 and charted by Fildes in c. 1821; called Deception Harbour, Port William probably after the brig Williams (Capt. W. Smith), Bay of Deception; also called Yankee Harbor, erroneously identifying this feature with Yankee Harbour (q.v.) within Greenwich Island; named Port Foster after Cdr H. Foster, RN (Mount Foster, q.v.), who made pendulum and magnetic observations at Pendulum Cove (q.v.) in 1829. The harbour was charted by an RN Hydrographic Survey Unit, 1948-49. The shores of the harbour were designated SSSI No. 21 under the Antarctic Treaty.
