The effects of erosion are visible in this view from the SW of two prominent stratovolcanoes on SW Umnak Island in the Aleutians. Mount Vsevidof (left) is a symmetrical, constructional volcano where frequent eruptions, which have continued into historical time, have overcome the effects of erosion. Recheschnoi volcano (right), in contrast, has been inactive for longer periods of time and has been extensively dissected by glaciers. Only small pyroclastic cones and lava domes have erupted during the past 10,000 years.

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.
