Akutan volcano forms the west part of Akutan Island in the eastern Aleutian Islands. The volcano's summit is truncated by a 2-km-wide (1.2 mi) caldera that contains a cinder cone visible here through a breach in the caldera rim as a dark, steaming hill. This cinder cone has been the site of frequent historical eruptions. View is to the south. U.S. Geological Survey photograph, date unknown.
