ResumoAbstract Structures interpreted as periglacial involutions found at the base of a fine-grained, channelfill sequence in deposits correlated with the First Salpausselkã end moraine at Tohmajärvi are described. The involutions are covered by fine sand of probably aeolian origin. The stratigraphy suggests that the aeolian activity in the area post-dates the periglacial structures and can be related to the exposure of fine, water-laid sediments resulting from the fall of the Baltic Ice Lake waters to the Yoldia Sea level. The periglacial phenomena are dated to the Late Weichselian (Younger Dryas).
