Golden Cap

Lyme Regis ~ Charmouth ~ Golden Cap

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.

How Landslides occur

Chesil Beach

Isle of Portland

The Fleet West Bay (west)

Pebbles are ’sorted!’

Portland (east)

The gradient of the beach can get very steep

The Isle of Portland

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

Weymouth is a traditional seaside resort. It is protected by the Isle of Portland.
