The decorated surface is roughly triangular, measuring about 40 cm by 55 cm, and faces south. On it, prehistoric hands pecked out cup-and-ring motifs, the characteristic prehistoric rock art form in which a shallow circular depression, the cup, is surrounded by one or more incised concentric rings. Two cup-and-ring combinations are present here, one retaining a portion of a second ring, and from that second motif a faint curved radial line extends outward. There are also up to five simpler cupmarks, small and shallow, between two and three centimetres across. The stone's surface is weathered and naturally striated, which makes reading the carvings a careful exercise in distinguishing the worked from the accidental.

The outcrop sits at around 156 metres above sea level in a level area of blanket peat, with cutaway bog to the west and the land rising steeply to the south-west. The Ballaghbeama Gap lies to the north-west and the Kealduff River runs close to the north-east, placing this modest carved stone within a landscape of considerable topographic drama. The rock art was documented by Finlay in 1973, and later incorporated into A. O'Sullivan and J. Sheehan's archaeological survey of the Iveragh Peninsula, published by Cork University Press in 1996. About 50 metres to the south, a small knoll carries a standing stone, suggesting that this corner of Derrynablaha held some kind of significance across time, even if the nature of that significance is no longer recoverable.
