BackgroundSnezhniy is a small late-Quaternary Icelandic-type basaltic shield volcano that was constructed near the eastern margin of a large NE-SW-trending graben running along the axis of the northern Sredinny Range. The smaller shield volcano Grechishkina was constructed NW of 2169-m-high Snezhniy, on the saddle between it and the Pleistocene Keveney volcano. 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.
