This ash plume rising above the summit of Karymsky during the early 1970's represents typical activity during its 1970-1982 eruption. It was constructed within a 5-km-wide caldera that formed about 6,000 years ago. The northern Karymsky caldera wall is seen across the center of the photo. It formed within the older Dvor caldera, with the caldera wall visible in the background.
