The decorated face looks westward, which is itself slightly unusual given the stone's northeast-facing slope, and what it holds are cupmarks, the small, deliberately ground or pecked depressions found on prehistoric rock art across Ireland and Atlantic Europe. Cupmarks are among the most enigmatic of all prehistoric markings; their purpose remains genuinely unresolved, with interpretations ranging from territorial or ritual signifiers to astronomical references, none of them conclusively proven.

The stone itself is roughly subrectangular in plan, measuring about 1.10 metres along its northeast-southwest axis and 0.80 metres across, and rising only 0.26 metres at its highest point. The decorated area is a modest patch, roughly 0.45 by 0.35 metres, bearing two principal motifs: a circular cupmark around 4 centimetres in diameter and an adjacent oval cupmark of similar dimensions. There may be the faint remnants of a surrounding ring around parts of the oval, though the surface is fractured and the traces extremely uncertain. A small pockmark sits a little further northwest on the same surface, and three possible pickmarks lie to the southeast. The boulder does not stand alone in the landscape; another piece of rock art lies approximately 15 metres to the south, and the setting is enclosed on three sides by a horseshoe of mountains running from the southeast around through south and west to north, with an open view down into the Behy River valley to the northeast. A low drystone field wall runs roughly east-west just under two metres to the northwest, and a stream passes close by.
