The boulder is triangular in plan, and it is the sloping south-westerly face, roughly a metre wide and one and a half metres long, that holds the carvings. Rock art of this kind, sometimes called cup-and-ring art, is among the oldest monumental tradition in Ireland, generally attributed to the Neolithic or Bronze Age. The forms are consistent across a broad Atlantic arc stretching from Galicia to Scotland, yet what they meant to the people who made them remains genuinely unresolved.

Aoibheann Lambe identified and recorded the panel in detail. The surface carries a cup-and-two-rings motif, the central cup measuring six centimetres across with an outer ring reaching twenty centimetres in diameter, from which a radial line runs upslope from the cup as far as the outer ring. Beside it sits a two-cups-and-ring motif, where one cup sits on a natural crack in the rock and a second, slightly larger off-centre cup lies to its right, both enclosed by a ring fourteen centimetres across. A short radial line extends from that larger cup in what Lambe describes as a four o'clock position, reaching only as far as the ring. Above and to the left of these two grouped motifs are three plain cupmarks, each around five centimetres in diameter. At the base of the carved panel, two narrow pocked horizontal grooves run parallel to one another, enclosing a band of the rock's surface between them, with some general pocking also present in the area. Another rock art panel lies immediately to the north-west of this boulder, suggesting that this part of Kerry preserves a small concentration of prehistoric carved surfaces rather than an isolated find.
