Tupuai High Sea

Tupuai, or Tubuai, is the main island of the Austral group in southern Polynesia, ringed by a lagoon formed by an encircling reef with a break on its northern side that lets ships pass. Its highest point, Mount Taitaʻa, rises about 422 metres, and six or seven islets lie along the reef. Cook mapped the island in 1777 under the name Toobouai, though his party did not land. The Bounty mutineers arrived in 1789.
