Kekuk crater on the lower northern flank of the Bolshoi-Kekuknaysky volcanic complex formed about 7,200 years ago. The 1-km-wide crater formed beside a lava dome (left) which likely was erupted immediately prior to formation of the crater. Bolshoi and Kekuknaysky are two large partially overlapping Pleistocene edifices that contain scoria cones on their flanks.
