Boulder shore
The shore on the south end of Porth Llawenan is a mass of dark-coloured, gabbro boulders derived by glacial action from the ridge stretching to the northeast. The dark colour is due to the gabbro intrusion which makes the hills a very special geological area of interest. The orange colours are due to Caloplaca liches on some surfaces.
