A fabulous dyke exposure, which shows not only the main mass of the basaltic intrusion to the left, but the sandstone strata into which it was intruded. The Triassic sandstone, which comprises a cream-coloured, laminated lower part overlain by more massive, red-coloured beds, has been hardened by its proximity to the heat of the magma rising in the dyke structure while it was still at depth during the Eocene. Although it is more resistant to erosion, the process is relentless, as can be seen by the lack of attached lichens at the tide mark. A litter of detached basaltic and sedimentary blocks cover the beach platform. My assistant is quite well camouflaged among them!
