Lake Kluchevoe occupies the Ksudach IV caldera, which was formed during major explosive eruptions about 6,000 years ago. This view looks across the caldera lake to the southern caldera wall. The caldera rim forms the right-hand horizon. The caldera wall in this photo consists of two caldera rims, Ksudach IV to the right, and the late-Pleistocene Ksudach II caldera rim to the left. The Zamok lava dome is across the lake to the left-center.
