ABSTRACT
The Russian Republic of Karelia, referred to as Karelia, occupies the north western part of the East European Plain. Ancient subaerial denudation plains, locally indicated by weathering crusts, are widespread in Karelia. Continental glaciations were the factor which substantially affected the present geomorphology of Karelia. The outlet glaciers confined to depressions became active and deposited the lateral ridges during the Younger Dryas Chron. It is easier to correlate the Younger Dryas marginal zones in Eastern Fennoscandia than the segments of the contemporary end moraine ridges that deposited at some earlier stages of Deglaciation. Younger Dryas Deglaciation is characterised by frontal retreat of the ice sheet margin. Individual end moraine ridges have been encountered at fairly high altitudes on the slopes of the Kandalaksha fell. Their formation during the Younger Dryas is, therefore, somewhat uncertain and they may have formed during earlier evolutionary phases.
