View from Location 1 across to the steeply dipping Carboniferous age limestone of Cold Knap Point

Looking in more detail to the right of the headland you can see the almost horizontal Jurassic aged rocks in the background

At Locality 3 you can see Carboniferous aged limestone with Triassic aged breccia overlying it. This is a time gap of about 100 million years of rocks that are missing between these two rocks

You can also see the crinoid fossils in the Carboniferous aged rocks

At locality 4 you can clearly see that the Triassic aged breccia contains lumps of the Carboniferous aged limestone
