Tolbachik
 Tolbachik is a volcanic complex on the Kamchatka Peninsula in the far east of Russia. It consists of two volcanoes Plosky (flat) Tolbachik (3085 m) and Ostry (sharp) Tolbachik (3682 m) which as the names suggest are respectively a flat-topped shield volcano and a peaked stratovolcano. As Ostry is the mountain's highest point the entire mountain is often referred to as Ostry Tolbachik not to be confused with Ostry a separate volcano to the north also on the Kamchatka Peninsula.
