Nature
Mount Carlisle is a stratovolcano on Carlisle Island in Alaska’s Islands of Four Mountains, part of the central Aleutian Islands and the remote volcanic chain of the North Pacific. The volcano fills most of an island about 4.3 miles across, and the island itself is roughly 5 miles wide. Though not especially high, it has a summit crater and a small glacier on its upper western slopes below the crater rim. A few eruptions have been recorded, but uncertainty surrounds that history because nearby volcanoes were often confused with one another and the area’s extreme isolation made reports of ash or steam difficult to confirm.
