Wednesday 25th August 10:00 am to 1:00pm. The walk is run as part of the Northumberland Coast AONB series of geo-diversity walks
Walk summary: Cocklawburn Beach is not only a stunnigly beautiful beach but it also contains a wealth of fossilised ancient life preserved within the layers of rock mapped out across the beach. When these layers of rocks were laid down about 350 million years ago this was a large shallow basin which over hundreds of thousands of years alternated between deltaic sands, mud and swamp and shallow tropical sea. In these tropical seas there lived a wide variety of sea creatures including crinoids, brachipods, corals, orthocones, fish and trilobites, and their shells and bones in their millions sank to the bottom of the sea to form lime rich layers. Over time these were turned into the hard limestone layers which delimit Cocklawburn Beach and the remains of the sea creatures can easily be found if you know where to look. This walk will take you out onto the limetone shelves and elsewhere in search of fossils along with an explanation of what they were and how they lived.
How long is the walk? This walk will be approximately 4 km and will involve some scrambling across rocks on the foreshore. Strong boots are recommended and some may find walking poles helpful.
What else do I need to know? Full details will be sent out on email to everyone who books. This will include what to bring and how covid guidance will be followed.
