A N-S-trending chain of basaltic cinder cones lies south of Bakening volcano, west of the Srednaya Avacha (Middle Avacha) river valley. The Kostakan cone group is part of a broad zone of regional basaltic volcanism affecting areas west of the Eastern volcanic zone of Kamchatka. It extends from the Kostakan Lake area to the south and has been active from the late Pleistocene to Holocene. Several of the cinder cones are breached by lava flows, some of which extend into the Srednaya Avacha valley. The highest-elevation vent, 1150-m-high Zmeya crater, was constructed within a landslide scarp. An unnamed maar is located about 2 km south of Kostakan Lake. Eruptions have occurred during two time periods, between about 11,000 to 7000 years ago and between about 1200 and 600 years ago.
