Late Weichselian periglacial features in south-eastern Finland and the surroundings of Lake Ladoga in Russia
Ice-wedge casts recorded from the Salpausselkä moraines in south-eastern Finland show that there was permafrost in this zone at the time of the Younger Dryas Stadial. The few sites with pocket involutions north and east of Lake Ladoga indicate that even this area had permafrost at the same time. Oth...
