Overview
Conical Ostry volcano (also known as Ostraya) is a late-Quaternary stratovolcano on the western side of the major NE-trending graben along the axis of the northern Sredinny Range. An unnamed cinder cone on the SW flank, informally referred to as "Cone X," erupted about 4,000 years ago, producing a basaltic lava flow.
