At Eype beach in Dorset, on England’s south coast, the Jurassic cliffs comprise an unstable combination of rocks that are prone to land slips, especially in wet weather. The Eype Clay Member near the top of the cliff is mostly composed of blue-grey micaceous mudstone. The layer can be 65 metres in depth with little stratification. It seems to liquefy when subject to heavy rain and then pours down to the shore. It eventually dries out, contracts, and cracks, resulting in an infinite variety of natural fracture patterns.
