Goodenough Island in the Solomon Sea (identified as Morata on the earliest maps) is the westernmost of the three large islands of the D'Entrecasteaux Islands in Milne Bay Province of Papua New Guinea. It lies to the east of mainland New Guinea and south west of the Trobriand Islands. It should not be confused with Goodenough's Island. It is roughly circular in shape, measuring 39 by 26 kilometres (24 by 16 mi) with an area of 687 square kilometres (265 sq mi) and a shoreline of 116 kilometres (72 mi). From a coastal belt varying in width from 2 to 10 kilometres (1.2 to 6.2 mi) in width, the island rises sharply to the summit of Mount Vineuo, 2,536 metres (8,320 ft) above sea level, making it one of the most precipitous islands in the world.
