Zimina Volcano — Russia

The eroded stratovolcanoes of Ostraya and Ovalnaya Zimina form a ridge north of the Udina complex at the SE end of the Kliuchevskaya volcano group. The larger Ovalnaya Zimina, on the W side of the complex, has a large icecap and contains two summits. The extensively eroded Ostraya Zimina to the E has a sharp-peaked summit spire. A large debris avalanche from Ovalnaya Zimina traveled more than 10 km. No eruptions are known to have occurred from these volcanoes.
