Bogoslof Island or Agasagook Island (Aĝasaaĝux̂^[3] in Aleut) is the summit of a largely submarine stratovolcano located in the Bering Sea in the U.S. state of Alaska, 31 miles (50 km) behind the main Aleutian volcanic arc. It has a land area of 173 acres (0.70 km²) and is unpopulated. The peak elevation of the island is 490 feet (150 m). It last erupted in 1992.
In 1909 President Theodore Roosevelt dedicated Bogoslof and neighboring Fire Island as a sanctuary for sea lions and nesting marine birds. Together, as the Bogoslof Wilderness, they are now part of the Aleutian Islands unit of Alaska Maritime National Wildlife Refuge. In November 1967, the island was designated a National Natural Landmark by the National Park Service. The islands were added to the National Wilderness Preservation System in 1970.
