Ostry
Ostry is a stratovolcano located in the northern part of the Kamchatka Peninsula, Russia. It comprises the higher Ostry volcano and the smaller Kutina volcano. Ostry is one of the highest peaks of Sredinny Range.
An unnamed high cinder cone on the SW flank of Ostry, informally referred to as "Cone X," erupted about 4,000 years ago, producing a basaltic lava flow.
