Symmetrical Klyuchevskoy and the eroded Ushkovsky edifice are seen here SW of the town of Klyuchi. The small Sredny cone, constructed on the eastern flank of Ushkovsky, occupies the saddle between them. Klyuchevskoy is one of Kamchatka's most active volcanoes and Ushkovsky has also erupted in historical time.
