Background:

Bolshoi (Bolshoy) and Kekuknaysky are two large, partially overlapping basaltic shield volcanoes located NW and NNW, respectively, of Uksichan volcano. The massive shield volcanoes are of Pleistocene age and were constructed west of the axis of the Sredinny Range. Hawaiian-type calderas are located at the summit of the volcanoes, and numerous youthful cinder cones dot their flanks. The summit caldera of Bolshoi is breached by four radial valleys, whereas the 6-km-wide caldera of Kekuknaysky (also known as Leningradets volcano) is breached to the north. Young cinder cones and lava flows are particularly abundant on the NE flank of Kekuknaysky volcano. Kekuk crater on the lower northern flank erupted about 7200 years ago.
