The circular caldera at the center of this International Space Station image with N to the upper right is Pizrak caldera. The Holocene Kell volcano is visible within the caldera. This remote volcanic complex in southern Kamchatka contains three partially nested 3-5 km wide calderas containing lava domes and cones, of which Kell is the highest. The larger edifice to the lower left is Zheltovsky.
