Cow Corner

Cow Corner is the north-western end of Worbarrow Bay, a small secluded bay on the south coast of the Isle of Purbeck, in Dorset England.

Worbarrow Bay and Cow Corner are located about six kilometres south of Wareham und about 16 kilometres west of Swanage. The bay lies directly south of the ghost village of Tyneham. Access to Cow Corner is only possible on foot when the Lulworth army firing ranges are open to the public, either from Tyneham, or alternatively via the South West Coast Path.

The Jurassic Coast is a World Heritage Site. The coastal exposures along the Jurassic coastline provide a continuous sequence of Triassic, Jurassic and Cretaceous rock formations spanning approximately 185 million years of the Earths history. The rocks along the Jurassic Coast dip gently to the east. Due to this tilting and due to erosion the oldest exposed rocks are found in the west. The younger Cretaceous rocks form the cliffs here in the east. Cow Corner and Worbarrow Bay are part of the Jurassic Coast.

The geology of the Isle of Purbeck is very complex and this is shown very clearly along this stretch of coast. The northern side of Worbarrow Bay is mainly Upper and Middle Chalk. This is subject to frequent landslides because of the unstable underlying Gault Clay. At the top of the cliffs is the Iron Age hill fort on Flower's Barrow, which is threatened by erosion on its seaward side. The Flower's Barrow ridge forms the western end of the ridge which runs all the way to Ballard Point north of Swanage. The Chalk cliffs become lower to the west of Cow Corner and just beyond they form a knife-edge ridge that drops down to the little Bay of Arish Mell, where a stream has cut a gap in the Cretaceous hills.
