Two overlapping shield volcanoes are located NW of Uksichan volcano, west of the axis of the Sredinny Range. Bolshoi (lower left), also spelled Bolshoy, is breached by four radial valleys and is the more eroded of the two volcanoes. Kekuknaysky (right-center), also known as Leningradets volcano, contains a 6-km-wide Hawaiian-type caldera breached to the north. Young cinder cones and lava flows are particularly abundant on the NE flank of Kekuknaysky volcano, forming the broad less vegetated area outside the caldera.

Kekuk crater on the lower northern flank of the Bolshoi-Kekuknaysky volcanic complex erupted about 7200 years ago. The 1-km-wide crater formed on the flank of a lava dome (left) which likely was erupted immediately prior to formation of the crater. Bolshoi (Bolshoy) and Kekuknaysky are two large, partially overlapping Pleistocene basaltic shield volcanoes located NW and NNW, respectively, of Uksichan volcano and are dotted with numerous youthful cinder cones on their flanks.
