Umnak (Unmax[2] in Aleut) is one of the Fox Islands of the Aleutian Islands. With 686.01 square miles (1,776.76 km2) of land area, it is the third largest island in the Aleutian archipelago and the 19th largest island in the United States. The island is home to a large volcanic caldera on Mount Okmok and is separated from Unalaska Island by Umnak Pass.
As of the 2000 census,[1] the island had a population of 39 persons. Its only remaining community, Nikolski, comprised the island's entire population. Fort Glenn, a former major military facility on the northeast shore of the island, played an instrumental role in the North Pacific Theater in World War II.
On Saturday July 12, 2008, Mount Okmok, located on Umnak, erupted, sending ash 50,000 feet (15,000 m) in the air and forcing the evacuation of Fort Glenn, a private cattle ranch located on the island.[3]
