Details for: Bogoslof
Bogoslof Island is the summit of a largely submarine stratovolcano located in the Bering Sea 50 km behind the main Aleutian arc. The island is about 1.5 x 0.6 km wide, and due to its frequent eruptive activity and energetic wave action, has changed shape dramatically since first mapped in the late 1700's. The conical, rubbly lava dome and offshore spire at the northern tip of the island (bottom center) were formed in 1992. The circular, flat area at the right is a remnant of the 1927 lava dome, and the steep pinnacle is Castle Rock, a 1796 dome remnant.
