Kamchatka (Russia): Kluchevskoy Volcanic Group

Klyuchevskaya Group of volcanoes has about a dozen volcanoes in close proximity and it is the most active area in Kamchatka, with one or the other volcanoes erupting at any given time. Exploring the area of the 1974 devastating eruption takes you through black pumice and lava flows, lava caves, bright-red cinder cones, stunted trees and an absolutely desolate and devastated landscape.
