Gamchen volcanic massif, comprising three Late Pleistocene and one Holocene cones, looking northwest. Reddish Holocene cone is named Baranii ("Sheep's"). It started to form about 3600 14C years BP as evidenced by stratigraphic position of its cinders immediately below AV1 marker ash (3500 14C years BP) from Avachinsky volcano. The cone has been formed in several spurts of activity during an interval of 3600-3000 14C years BP. Kizimen volcano is seen at the background left of the Gamchen summit.
