Bogoslof Island
Bogoslof Island

Located within Alaska Maritime National Wildlife Refuge, Bogoslof Island, a product of several volcanic eruptions, is recognized by geologists to be a prime example of volcanism at work. The most recent eruption in 1992 added a new dome to the east end of the island. The island supports an important rookery and haulout for endangered Steller sea lions, and nesting grounds for over 50,000 murres, kittiwakes and other sea birds.
