The glaciotectonic deformations near the northeastern margin of the Sudetic Foreland, SW Poland. were formed during one glacial episode. They are relatively small and are truncated. Deformation structures have no recognizable relationship to the thick Neogene clay in the basement; they have variable relations to the morphology and indicate transverse to opposite directions of the glacial push in very small areas within a distance of 2 to 5 km. This suggests an unusual deformational history. Deformations have probably been created due to sliearing en masse of the anisotropic sediments and during the ice‐sheet advance. Deformation structures have been formed a few kilometres ahead of the curved ice margin, which created ‘glaciotectonic hills’ with strongly differentiated orientations of thrust structures and folds.
