Clouds drape the margins of the glacier-covered summit caldera of Ushkovsky (Plosky) volcano in the foreground. Two of the highest volcanoes in Kamchatka, Klyuchevskoy (left) and Kamen (right) rise above the layer of clouds to the SE. A small ash plume drifts above the summit of Klyuchevskoy, one of Kamchatka's most active volcanoes.
