Cliff section east of Amroth 1

Telpyn Point to Amroth

Between Amroth and Telpyn Point, magnificent cliff sections expose the upper Namurian sequence of deltaic channel-fill sandstones and intervening shale sequences.

About 1.5 km east of Amroth, this photo shows the sequence gently dipping to the west. The dark mudstones of the Gastrioceras subcrenatum Marine Band which marks the base of the Coal Measures can be seen near the top of the cliff. This is underlain by the Telpyn Point Sandstone (formerly designated as the Upper Sandstone), the uppermost main sandstone in the Namurian, and originally known as the 'Farewell Rock', so called because exploratory boreholes and shafts for coal penetrating the sandstone would no longer encounter any workable coals. Underlying the sandstone is a shale sequence, with another sandstone (pale brown-grey) visible near the base of the cliff.
