Underhill is the name given to the area of very steep land, at the northern end of the Isle of Portland in Dorset, England, which contains the villages of Chiswell, Castletown and Fortuneswell. The remaining part of the island is known as Tophill. The geology of Underhill is different from Tophill; Underhill lies on a steep escarpment composed of Portland Sand, lying above a thicker layer of Kimmeridge Clay, which extends to Chesil Beach and Portland Harbour. 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.
