The possible shooting butt is located on a rock outcrop near the summit of Pen Cerrig-calch. It consists of about eight stones, each roughly 0.2 metres across, placed on top of a boulder measuring about 1 metre across. It would act as a hide from the upslope, northwest side, though a person would be exposed from the southeast side. N.A. Vaughan, ArchaeoPhysica Ltd, 10/05/2007
