Towering over Worbarrow Bay to the north is Flower's Barrow ridge, which due to coastal erosion is gradually falling into the sea.
Flower’s Barrow forms the western end of the ridge which runs all the way to Ballard Point, north of Swanage.
These range from the chalks at the northwest end of the bay, at Cow Corner, that are between 85 and 145 million years old, through to the hard stone outcrop in the east.
The cliffs and the tout have distinctive angular layers of rock that visibly demonstrate the complex sedimentary folding that affected this area some 30 million years ago.
The Purbeck lagoonal limestones and the shales that are exposed in the cliffs of Worbarrow Tout contain dinosaur footprints and have abundant brackish water bivalves, gastropods and ostracods.
