| The symmetrical Vsevidof stratovolcano, near the SW end of Umnak Island, is one of the most prominent volcanoes in the Aleutians. Vsevidof contains a 1.2-km-wide, ice-filled summit crater that is breached by glaciers on the east and north sides. An E-W-trending zone of scoria cones that extends from 1220 m down much of the western flank has been the source of historical eruptions. The bulk of the 2149-m-high cone of Vsevidof was constructed during the Holocene. Young andesitic and dacitic lava flows were extruded from vents on the north and south flanks and on the west-flank rift. The largest lava flow traveled down the west flank to the coast, forming Cape Kigushimkada. | |||
