Klyuchevskaya Sopka

Kamchatka Peninsula, Russia

Eurasia most active and tallest volcano at 4,750m — a near-perfect stratovolcano on the Kamchatka Peninsula that erupts almost continuously. Surrounded by a cluster of volcanic cones in the Klyuchevskoy group, its contour lines radiate outward with textbook symmetry while glacial valleys gouge deep into its flanks. One of the most remote and dramatically vertical landscapes on the Pacific Ring of Fire.
