A lahar produced by the melting of snow and ice during a February 4-9, 1978 eruption of Westdahl volcano in the Aleutians is seen in the foreground of this summer 1978 photo taken near Scotch Cap on the SW coast. The lahar traveled 12 km from the summit, visible at the upper left. The 1978 eruption blasted a 1.5-km wide, 500-m deep crater through the summit icecap.
