A 750-m-wide crater filled with a lake truncates the summit of Kasatochi. Crater walls rise to a maximum height of 314 m above the lake surface, which is less than 60 m above sea level in this 1961 photo. The volcano is located at the northern end of a shallow submarine ridge trending perpendicular to the Aleutian arc and occupies an island volcano 2.7 x 3.3 km wide.
