The rocks along the Jurassic Coast dip gently to the east. Due to this tilting and erosion the oldest exposed rocks are found in the west. The younger Cretaceous rocks form the cliffs here in the east.

Geology

The Tout has a distinct pointed shape. It has steep angular layers of rock that visibly demonstrate the complex sedimentary folding that affected this area and that were caused by tectonic pressures as the African and European continents collided some 30 million years ago. The cliff sediments were then twisted horizontally and this is why the Chalks that are between 85 to 145 million years old are found at the rear of the bay. The sediments that face the sea at the front of the bay and form the peninsula Worbarrow Tout are the 150 million year old Portland limestone
