A series of parallel ridges and gullies running northeast to southwest on Bwlch y Pridd Common. The ridges are 2 metres apart. They are probably associated with the earthwork features to the east, NPRNs 534565-534568. A trackway shown on the 1st edition Ordnance Survey map appears to cut across the ridges. J.J.
