I believe i was right regarding the ice dam collapse at the western end of the Esk Valley being responsible for the superficial geology of the south western area of Cleveland. The central Esk water body if released suddenly would have created what we see today, ive already proven the area is not covered in till or boulder clay as stated by Aygar. it is in fact covered with alluvial deposits and complexed clays, that contain animal and human sub fossils.
