"Plosky is a small late-Quaternary Icelandic-type shield volcano located south of the Bolshaya Kimitina River. Plosky lies SE of Ichinsky volcano near the SE margin of the Sredinny Range. The 1236-m-high summit of Plosky consists of a small basaltic stratovolcano overtopping the lava shield. Early geologic studies in the Sredinny Range (Ogorodov et al., 1972) identified numerous Holocene eruptive centers based primarily on morphological criteria. However, later work has suggested that Sredinny Range volcanoes are less mantled by Holocene tephras than eastern Kamchatka volcanoes and therefore appear more youthful, so that Holocene eruptions are uncertain for many of these Sredinny Range eruptive vents."  -Smithsonian Volcano Archive
