This Kimmeridge Clay has resulted in a series of landslides, forming West Weares and East Weares.

Chesil Cove is a curved steep bank forming the south-east end of 29-kilometre (18 mi) Chesil Beach in Dorset, England. It is thus part of one of three large shingle structures in Britain, extending from West Bay to the Isle of Portland (Portland Bill), the latter acting more firmly as a great barrier (groyne) which stops tidal action from washing the beach away and leads to the high depositions by wind and tide action forming the grand curved bank of this "cove". The "cove", bill and much of Chesil Beach give shelter from the prevailing winds and waves for much of Weymouth Bay, the town of Weymouth and the village of Chiswell. It forms part of the Jurassic Coast.

It was in operation from 1826 to 1939. Since becoming disused the original path of the railway has become a popular public footpath.
