Structural analysis of the so-called disturbances in the Pleistocene deposits and underlying Cretaceous flint-bearing Chalk in a small coastal area north of Weybourne, eastern England, indicates that only one major ice sheet has overridden the area. The ice moving from the SSW-SW, approximately 210 degrees, was deflected into a more northerly course and caused deformation and deposition of a chalky boulder clay considered equivalent to the till of the Lowestoft advance. Structural evidence of a preceding Cromer advance has been obscured.
