This stone lies 10 paces west of the path junction or perhaps more obviously, 30 paces NW of the NW leg of the pylon. The incisions are up to 20 cm long and 2 cm deep.
Coflein describes it as “an arrow stone on the west side of the track near ffridd newydd. It is a natural boulder measuring 2m by 1m and on the upper surface of the stone are groups of parallel cuts from 10-18cm long.”
