Overview
The symmetrical Mount Cleveland stratovolcano is situated at the western end of the uninhabited Chuginadak Island. It lies SE across Carlisle Pass strait from Carlisle volcano and NE across Chuginadak Pass strait from Herbert volcano. Joined to the rest of Chuginadak Island by a low isthmus, The native name, Chuginadak, refers to the Aleut goddess of fire, who was thought to reside on the volcano.
Numerous large lava flows descend the steep-sided flanks. It is possible that some 18th-to-19th century eruptions attributed to Carlisle should be ascribed to Cleveland (Miller et al. , 1998).
In 1944 it produced the only known fatality from an Aleutian eruption.

About the Photo
Mount Cleveland forms the western half of Chuginadak Island. This 24 July 1994 view from the west shows the summit region darkened by ashfall that may have originated from an eruption reported on 25 May. Dark lava flows from earlier eruptions can be seen on the flanks.
