The cliff top at Black Ven
Black Ven between Lyme Regis and Charmouth. Upper Greensand lies
over Lower Jurassic clays. The largest coastal
mudflow in Europe took place here in the winter of
1958/9
The coast is unstable because there are numerous situations where porous strata, principally the Chalk and Upper Greensand, lie over impermeable clays.

When the island was uplifted, a series of massive fractures developed in the limestone.
