Caption: Mynydd Llanhilleth. Looking NNW.
Description: Mynydd Llanhilleth. Looking NNW. Washout in High Wall of abandoned opencast site, Mynydd Llanhilleth. The Mynyddislwyn Seam runs just above the level of the pond and marks the base of the Grovesend Beds, the well-jointed basal 'Pennant' sandstones of which form the 20 m. cliff above. In the left centre of the picture above the cliff, two coaly rashings horizons (the Lower and Upper Small Rider) are just visible at the bottom and top respectively of a series of thin-bedded sandstones and seatearths, 11 m. thick. The top coal is 'washed out' by the succeeding 8 m. of sandstone which can be seen channelling down on the right of the picture. Deposits of paler head and darker opencast spoil extend to the skyline.
