Boulder depressions in central Sweden. Remnants of a pre-Late Weichselian landscape?

Auteur :

Description :
During geomorphological mapping of an area in central Sweden, it was found that areas of boulder depressions tended to be mutually exclusive with drumlinized and Rogen moraine areas of Late Weichselian origin. This irregular erosion pattern probably reflects the fact that the Late Weichselian ice sheet was partially frozen to its bed. If the situation is the same in other parts of Fennoscandia, boulder depressions may prove to be a helpful feature when searching for warm- and cold-based areas of the Late Weichselian ice sheet.
