The symmetrical Vsevidof stratovolcano, near the SW end of Umnak Island, contains a 1.2-km-wide, ice-filled summit crater that is breached by glaciers on the E and N sides. An E-W-trending zone of scoria cones that extends down much of the W flank has been the source of recorded eruptions. Most of the cone was constructed during the Holocene. Andesitic and dacitic lava flows originated from vents on the N and S flanks, and on the W-flank rift. The largest lava flow traveled down the W flank to the coast, forming Cape Kigushimkada.
