Bobrof Island

Bobrof Island (Aleut: Walĝa) is one of the Andreanof Islands subgroup of the Aleutian Islands in southwestern Alaska, USA.^[4] Bobrof Island is a small, uninhabited island about 9 miles (14 km) north and west of Kanaga Island, and 7 miles (11 km) northeast of Cape Sudak on Tanaga Island. Bobrof Island is 2.6 miles (4.2 km) long and 1.8 miles (2.9 km) wide with an area of 3 square miles (7.8 km²), and consists primarily of the 2,421-foot (738 m) high Bobrof Volcano.^[4] The volcanic crater, or cone, has been heavily dissected.^[5] Underwater deposits adjacent to the island's northeast flank suggest an immense debris-avalanche has taken place.^[4]
