BackgroundThe eroded twin stratovolcanoes of Ostraya and Ovalnaya Zimina form a NW-SE-trending ridge north of the Udina complex at the SE end of the Kliuchevskaya volcano group. The larger 3081-m-high Ovalnaya Zimina, at the NW end of the complex, is capped by a large icecap and contains two summits. The extensively eroded Ostraya Zimina to the SE has a sharp-peaked summit spire. A large debris avalanche from Ovalnaya Zimina traveled more than 10 km. No historical eruptions have occurred from the Zimina volcanoes.
