This photograph clearly shows the chalk of the Certatious era and is one of the youngest rock types to be seen on the Jurassic Coast. Chalk is a soft, very finely grained limestone formed from a 'mud' of calcium carbonate, often made up of the shells of tiny marine organisms
These cliffs, Durdle Door and Lulworth Cove can be seen to thier best advantage from the sea, on boat trips from Lulworth and Weymouth
For information there is a Heritage Centre at Lulworth Cove
