Kamen (left), Klyuchevskoy (right), and the broad snow-capped Ushkovsky behind them to the west, form the northern end of the Klyuchevskaya volcano group. Ushkovsky consists of the flat-topped Ushkovsky volcano on the left, which is capped by an ice-filled 4.5 x 5.5 km caldera, and the adjacent slightly higher Krestovsky peak on the right.
