Four Mountains
Mount Cleveland is an almost symmetrical andesite stratovolcano in the Islands of Four Mountains, a volcanic group in the Aleutian Arc. Like all stratovolcanoes, Mount Cleveland grew as explosive eruptions, effusive eruptions, and lahars built it layer by layer into a convex shape. It lies southeast of Mount Carlisle and northeast of Herbert Island. Mount Cleveland forms the western half of Chuginadak Island, a broad and uneven bell-shaped landmass, and is the highest of the four volcanic islands. The island is completely uninhabited; the nearest settlement is Nikolski on Umnak Island, about eastward.
