Review of the Salpausselkä ice‐marginal formations in Finland
Journal of Quaternary Science, EarlyView.ABSTRACT Extensive Salpausselkä ice‐marginal formations were deposited in southern and eastern Finland during the Weichselian deglaciation. These comprise three major ridges (I, II, and III Salpausselkäs) and their eastern counterparts (Tuupovaara, Koitere, and Pielisjärvi), together forming laterally continuous ice‐marginal formations extending ...
