That hollow, a cupmark roughly seven centimetres across and two and a half centimetres deep, is easily overlooked. Cupmarks are among the most enigmatic traces left by prehistoric people across Ireland and Britain: simple circular depressions ground or pecked into rock surfaces, found singly or in clusters, on boulders, outcrops, and megalithic monuments alike. What they meant, whether ritual, territorial, astronomical, or something else entirely, remains genuinely unknown.

The boulder itself is not large, about 1.2 metres long and 0.6 metres high, and it sits on a northwest-sloping surface amid ferns, gorse, and heather. A nearby oval depression in the same stone was judged to be a natural feature rather than an intentional mark, which is a reminder of how carefully such distinctions have to be made when reading ancient surfaces. What gives the site a little more weight is that a second cupmarked stone lies roughly fifteen metres to the south, suggesting this patch of hillside was, at some point, a place where people repeatedly chose to leave their mark on the landscape, modest as those marks appear today.
