Summit area of Westdahl volcano located on the southwest part of Unimak Island in the eastern Aleutian Islands. The topographic peaks in the distance are Westdahl Peak (left) and Faris Peak (right). The cinder cone in middle ground marks the principal vent for the 1991 to 1992 eruption. Note the snow-mantled lava flow emanating from cinder cone. The sinuous fissure cutting the ice cap formed in the opening phases of the eruption and was the location of spectacular lava fountaining.
