Space Shuttle photo STS047-077-034 looking northwest across the western end of the Alaska peninsula and the north-eastern tip of Unimak Island. The Cold Bay volcanic field, including the Holocene stratovolcanoes of Frosty Peak, are shown.
Frosty Peak has undergone at least two episodes of stratovolcano formation and collapse. The older cones have been glaciated.
