Dzenzursky is a strongly eroded stratovolcano of Pleistocene age that lies along a ridge extending NW from Zhupanovsky volcano. The broad snow-capped Dzenzursky massif is seen here from the NE with the rim of the summit crater of Karymsky volcano in the foreground and conical Koryaksky volcano in the left distance. A series of cinder and lava cones along a ridge trending east and SE of Dzenzursky produced extensive fresh-looking lava fields. Two historical eruptions of uncertain validity have been reported.
