Background
Severny Cherpuk (South Cherpuk) and Yuzhny Cherpuk (North Cherpuk) are two cinder cones SW of Ichinsky volcano that comprise the largest monogenetic volcanoes of the Sredinny Range. Severny Cherpuk, 21 km SW of Ichinsky, is a double cone that was constructed along the crest of the Sredinny Range and fed massive 1.8 cu km lava flows down both sides of the range to the NW and SE. A narrow tongue of the SE flow diverted an addition 10 km to the south, for a total distance of 22 km. Yuzhny Cherpuk, 11 km SSW of Ichinsky volcano, produced a 1.7 cu km lava flow that traveled 18 km to the south and then SE. The flow descended to 640 m elevation and dammed tributaries of the Ketachan River, producing three lakes. The two cones are sometimes considered to be satellitic cones to Ichinsky, but Pevzner et al. (2000) noted petrological distinctions that suggest an origin independent of Ichinsky. Unpublished radiocarbon ages revise those in Pevzner et al. (2000) and indicate that both cones were formed about 6500 years ago.---
