The carvings are faint, worn down by centuries of exposure, yet once your eye adjusts to the surface, the pattern that emerges is surprisingly intricate: a central curvilinear groove running more than a metre across the rock, with four shorter curved branches splitting away to the north, each one terminating in either a simple cupmark or a cup-and-ring motif. Cupmarks are shallow, roughly circular depressions pecked into stone, a common element in prehistoric rock art across Atlantic Europe; cup-and-ring motifs add one or more concentric rings around the central depression. Two of the branch grooves here end in these ringed forms, and the southernmost is the best preserved of the group, its ring and cupmark still measurably distinct despite the weathering. Two further cupmarks with radial grooves sit to the south of the main composition, giving the whole surface a quality that is more organised than accidental.

The boulder itself is a subrectangular block of sandstone, fractured but smooth across much of its decorated face, which has a sharp southeast-facing aspect at around 170 metres above sea level. It sits to the northwest of a stream, with long views down over the Behy River valley to the northeast and mountains rising to the south, west, and northwest. The purpose of such carvings remains genuinely unresolved. Atlantic rock art of this kind dates broadly to the Neolithic and Bronze Age, and while the motifs appear across Ireland, Scotland, and the Iberian Peninsula, their meaning, whether territorial, ceremonial, astronomical, or otherwise, has never been established with any confidence. What is clear at this particular site is that the stone was not chosen carelessly: its elevated position and the orientation of the decorated surface suggest the maker, or makers, had a specific relationship in mind between the carvings and their wider landscape. A second piece of rock art lies approximately two and a half metres to the south, making this a small concentration of carved surfaces rather than an isolated find.
