Walking along the beach, one can see three primary layers of rock exposed in the cliff face.
This soft sediment was later compacted and hardened to form chalk.
The Hunstanton Formation in the middle was formed during the lower cretaceous period over approximately 15 million years.
The dark orange-brown rock layer at the base is sandstone rich in iron ore, and hence the colour.
It has been used widely in buildings around the county.
Fossils are reported within the Carstone and include rolled ammonite fragments, bivalves and traces of burrowing organisms.
