Details for: Vsevidof
Mount Vsevidof is a symmetrical, 2149-m stratovolcano on SW Umnak Island. The historically active volcano, seen here from the south, contains an E-W zone of scoria cones on the west flank that fed many lava flows, including a large one that reached the west coast of the island and formed Cape Kigushimkada. A 1.2-km-wide summit crater is breached by glaciers on the north and east sides. Photo by Chris Nye (Alaska Division of Geological & Geophysical Surveys).
