- Аннотация: Abstract—After the end of the Mikulino interglacial, in connection with the increasing cooling trend, theScandinavian ice sheet began to form on the territory of Fennoscandia. Its development to the maximumboundaries was accompanied by ice sheet advances or, on the contrary, strong retreats that ref lected numer-ous successions of colder and warmer climate phases over a long period, called the Valdai (Weichselian, Vis-tulian) ice age. The Scandinavian ice sheet did not reach its maximum simultaneously at the different lobes.The age of the maximum boundary on the continent becomes younger from west to east, which is associatedwith the paleoclimatic setting in the northern part of Eurasia due to the formation of the extracontinental cli-mate. The climate continentality increased eastward along the periphery of the ice sheet. These climate fea-tures and the ice sheet response determined the nature of glacial morphogenesis in the proglacial zone. Theconditions for the formation of the peripheral ice sheet and the increase in the number of mudflows and theformation of glacial lakes were more favorable during the ice sheet degradation than expansion. The forms ofactive and dead ice, especially the terminal moraines and kames of different types, the valleys of marginalmeltwater channels, and outwash plains serve as the hallmarks of the stages of warming and degradation ofice sheets.
