(Platforms of Limestone on the foreshore, natually made by the sea) - 2002

Over 200ft of Lower Lias clays and limestone is present at West Quantoxhead, These dip eastwards. The Lias are similar to those of 'Church cliff', Lyme Regis in Dorset. Here they are known as the Quantock's beds and are 20m thick. The major faults along this part of the coastline can be clearly seen, especially with the hard limestone blocks on the foreshore which in some cases form stepped circles, almost hard to believe that this has been naturally made by the sea.
