Abstract
Ice wedge casts, the biggest 1.5 m deep, were found in stratified sand and gravel in sections in the Salpausselkä I end-moraine in eastern Finland. Their distribution suggests that they were formed in the end of the Late Weichselian Younger Dryas period and possibly in early Flandrian time, which agrees with the dating of the youngest ice wedge casts in southern Sweden and Scotland formed in the Younger Dryas period.
