Summary:The ice-cored ridges are important for palaeogeographical studies of retreating margins of glaciers. Earlier recon-structions of ice-cored ridges in marginal zones of the Pleistocene ice-sheets have been made based on sedimentological studies.Applying such approach, research were able only to show in which degree depressions between ice-cored ridges influencedspatial variations in depositional processes. There is possible to determine more precise characteristics of ice-cored ridgesgeometry based on detailed analysis of collapse structures. The shape, elongation and orientation of ice-cored ridges can bederived from geometry and kinematics of folds and faults as major elements of the collapse structures. Integration sedimento-logical studies of supraglacial deposits with analysis of collapse structures also allows to determine the evolution of ice-coredridges up to final deicing. This approach is the subject of case study performed in Daszyna site located in the Kutno Moraine.
