Geology at Pen Anglas
Geology at Pen Anglas
Rocky headland is owned by the National Trust and famed for its remarkable rock formations. "Pen Anglas is formed of a dolerite intrusion, and on the NE-facing cliffs below the stone pillar there are some excellent examples of columnar jointing. This inclined rock face shows sections through the columns demonstrating the hexagonal cooling joints. Climb over the ridge to the SW side of the headland where the long axes of the columns can be seen. The whole intrusion therefore appears to be dipping at about 450 towards the NE where the upper surface is exposed."
