The Baltic Ice Lake is a name given by geologists to a freshwater lake that gradually formed in the Baltic Sea basin as glaciation retreated from that region at the end of the Pleistocene. The lake, dated to 12,600-10,300 BP, is roughly contemporaneous with the three Pleistocene Blytt-Sernander periods. The lake followed a period of massive glaciation in the region, which followed the end of the Eemian Sea. The post-glacial Yoldia Sea was immediately subsequent to the Baltic Ice Lake.
