Tanaga Island (Aleut: Tanax̂ax;[2] Russian: остров Танага) is an island in the western Andreanof Islands, in the southwest part of the Aleutian Islands, Alaska. The island has a land area of 204 square miles (528 square kilometres), making it the 33rd largest oceanic island in the United States. Its highest point is volcano Mount Tanaga (Aleut: Kusuuginax̂[2]) at 5,925 feet (1,806 metres).
Tanaga Island measures 43 kilometres (27 miles) long and 38 kilometres (24 miles) wide.
Tanaga Island is about 62 miles (100 kilometres) west of Adak Island, the nearest inhabited island. There are several large waterfalls on Tanaga Island. Tanaga Island is uninhabited, but several cabins are shown on the NOAA nautical chart, as well as some Aleut villages on the east side of the island.[3]
There are no native land mammals on Tanaga Island.
Tanaga Island was established as a Navy emergency landing field in July 1943 as an adjunct to the Adak Naval Operation Base. Seabees of Naval Construction Battalion 45 built a runway, small-craft pier, mooring area, office and storage buildings, radio building, galley and mess facilities, dispensary, and 4 miles (6 kilometres) of gravel road in 1943, near Lash Bay in the southwest of the island. The site was abandoned in 1945. The control tower is still shown on nautical charts.
