Key Info
  • Old Harry Rocks, Dorset
  • Duration: 04:45
  • Old Harry Rocks in Dorset stand at the tip of a chalk headland between the bays of Studland and Swanage. Chalk is made up of fossilised remains of single-celled organisms which lived in the sea. Over thousands of years, millions of fossils became compressed to form the rock. As sea levels fell, the chalk became exposed. Old Harry Rocks form a headland as the chalk is more resistant to erosion than the clays on either side. With thanks to the British Geological Survey. Ordnance Survey mapping © Crown Copyright.
