The coastline of Unalaska is markedly different in appearance than other major Aleutian Islands, with numerous inlets and peninsulas.[5] In October 1778, English explorer James Cook visited the island for three weeks on his third voyage, and spelled it Oonalashka in his journal.He published drawings along with Aleut species names of the painted driftwood models,[8] which are preserved in Berlin.[9][10][11] In Moscow on May 31, 1988, President Ronald Reagan mentioned the meeting of Americans and Russians on this island in the 19th century as an example of early US-Russian friendship.On December 8, 2004, the Malaysian cargo ship Selendang Ayu ran aground off Unalaska Island, causing a large oil spill.
