This 1992 view up the eastern flank of Westdahl was taken two months after the end of a major E-flank eruption. The dark lava flows are from the 1991-92 eruption. The eruption took place from an 8-km-long fissure that extended from the summit down the east flank. It began on 29 November 1991 with a 6-km-high ash plume. The lava flow traveled as far as 7 km from the vent, widening as it reached the lower flanks. Photo by C. Dau, 1992 (U.S. Fish and Wildlife Service, courtesy of Alaska Volcano Observatory).
