The dacitic-to-rhyolitic Spokoiny stratovolcano lies immediately south of Ostry volcano and NE of Iktunup volcano in the northern Sredinny Range. The volcano, also known as Kutina, was active during the early and mid-Holocene. Deposits from five eruptions during this interval have been documented, the last of which took place about 5400 years ago. Cinder cones are located on the W flank, and lava flows from the symmetrical summit cone extend down drainages to both the east and west.
