Looking westnorthwest along the top of the axial stone, to show the cup shaped depression, similiar to that at (possibly) Carrigagrenane NE and Drombeg. Located here at the left hand side, from a position inside and facing the stone, it is regular and even in shape, measuring about two and a half inches in diameter and about a third of an inch deep.
