Ushkovsky is a large compound volcanic massif located at the NW end of the Klyuchevskaya volcano group. Seen here from the NW, it consists of the flat-topped Ushkovsky (far right), which is capped by an ice-filled 4.5 x 5.5 km caldera, and the adjacent higher Krestovsky peak (center). Numerous scoria cones have formed on its flanks.
