It sits incorporated into the wall of a small enclosure, its surface carrying a cluster of prehistoric cup-marks, those shallow, deliberately ground circular depressions whose precise meaning remains one of Irish archaeology's more stubborn puzzles. The boulder is not large, roughly 1.75 metres across its longest axis and about 0.4 metres high at its western end, but its decorated face looks east across the Behy river valley toward the Seefin and Droum Mountains, a placement that feels deliberate even if we cannot say why.

The decorated surface itself measures roughly 0.9 metres by 0.35 metres and bears three well-preserved cup-marks arranged in a triangular pattern near the highest point of the stone. Each is between 4.5 and 5 centimetres in diameter and cut to a depth of 6 to 7 millimetres, which is a reasonable degree of effort for a hand-worked hollow in sandstone. A fourth cup-mark on the northern edge is shallower, around 3 millimetres deep, and a possible fifth to the south-east has worn down far enough that it is difficult to distinguish from a natural solution mark, the kind of shallow pit produced by weathering rather than human intent. Sitting adjacent to the south-west of the decorated surface is a small square of metal, just 6 millimetres across, whose origin and purpose go unrecorded. The boulder also adjoins a hut site to its west, suggesting this was once a place where people lived, though the relationship between the domestic structure and the carved stone is not documented. At 189 metres above sea level, the setting is exposed heath, with a drystone wall about 12 metres to the south-east and a stream roughly 14 metres beyond that.
