Background:

Conical Ostry volcano, its slopes partially mantled by glaciers, is a late-Quaternary stratovolcano that rises to 2552 m, forming one of the highest peaks of the northern Sredinny Range. Ostry, also known as Ostraya, is located on the western side of the major NE-trending graben along the axis of the northern Sredinny Range. An unnamed 2127-m-high cinder cone on the SW flank of Ostry, informally referred to as "Cone X," erupted about 4000 years ago, producing a basaltic lava flow.
