Mount Vsevidof at a Glance

About Mount Vsevidof

Mount Vsevidof is a stratovolcano on Umnak Island in the Aleutian Islands of Alaska and is a prominent peak in the local island landscape. It is part of the Aleutian volcanic arc.

The mountain presents a steep volcanic cone with glaciers and snowfields near its summit and rugged terrain on its flanks. Access is very limited; there are no developed trails or visitor facilities and visits are typically undertaken by scientific teams, experienced mountaineers, or by boat/air from other Aleutian islands.

The volcano formed as part of subduction-related volcanism along the Aleutian arc. Its volcanic structure and deposits reflect repeated eruptive episodes during the Holocene and Pleistocene, although detailed eruption chronologies require specialist sources.

The peak sits on Umnak Island in western Alaska’s Aleutian chain, well offshore from mainland Alaska. The island is remote from major population centers and lies within a maritime, often stormy environment.

  • Access: Located on Umnak Island in the central Aleutian chain, the volcano is remote and reached only by boat or charter air services; there is no regular tourist infrastructure.
  • Volcanic setting: Part of the Aleutian volcanic arc, it is a prominent volcanic cone visible across surrounding lowlands and the nearby sea.
