Egmont Bight

Egmont Bight is a shallow embayment at the southern end of the Encombe valley in Dorset, England

Geology

The bay exposes good sections of Upper Kimmeridge shale and mudstone, with some bituminous shale and some small calcareous nodules.^[1]

On foot the stony beach is only accessible at low tide by walking 1.0-kilometre (0.6 mi) west around Egmont Point from the beach at Chapman's Pool. There is no safe route down from the clifftop coast path, across Houns-tout cliff, nor around the Freshwater Steps promontory at the beach's western end.

The Jurassic Coast stretches over a distance of 153 kilometres (95 mi), from Orcombe Point near Exmouth, in the west, to Old Harry Rocks on the Isle of Purbeck, in the east ^[2]. The coastal exposures along the coastline provide a continuous sequence of Triassic, Jurassic and Cretaceous rock formations spanning approximately 185 million years of the Earths history. The localities along the Jurassic Coast includes a large range of important fossil zones.
