 In the more maritime and generally wetter Russian Far East , Kamchatka , exposed during winter to moisture from the Aleutian Low , has much more extensive glaciation totaling around 906 km2 ( 350 sq mi ) with 448 known glaciers as of 2010 . Despite generally heavy winter snowfall and cool summer temperatures , the high summer rainfall of the more southerly Kuril Islands and Sakhalin in historic times melt rates have been too high for a positive mass balance even on the highest peaks . In the Chukotskiy Peninsula small alpine glaciers are numerous , but the extent of glaciation , though larger than further west , is much smaller than in Kamchatka , totalling around 300 square kilometres ( 120 sq mi ) .
