One surface holds the abstract circular grammar of prehistoric rock art; the other, running along the spine of the same stone, carries an ogham inscription, the early medieval alphabet of notched lines that was used in Ireland roughly between the fourth and seventh centuries AD. The two traditions sit close enough to touch, which is itself unusual.

The western rock, a fractured sandstone measuring about 2.9 metres north to south, bears the more elaborate carvings. Its decorated face carries a central cup-and-four-ring motif, the concentric rings radiating out from a small carved hollow, with a fourth ring that was cut short by a natural fracture in the stone. Beside it are a single cup-and-ring, a plain ring, and a loose cupmark. Cup-and-ring art of this kind is a widespread feature of the Atlantic Bronze Age, though its precise meaning remains unresolved. The eastern rock, unfractured and slightly larger, holds seven plain cupmarks on a west-facing surface at its northern end. What complicates the picture further is a cross-like pattern recorded on the outcrop, noted as resembling motifs described by O hÉailidhe in a 1958 article on the Rathdown slabs, a group of decorated stones associated with early Christian contexts in the Dublin and Wicklow area. If that parallel holds, it suggests the site attracted attention and perhaps re-use across a very long span. The ogham inscription runs 0.93 metres along the stone's edge, adjacent to the rock art rather than overlapping it. About 150 metres to the south, a single standing stone occupies the same field. The site sits in the valley of the River Maine, with the Gap of Dunloe visible to the south and the MacGillycuddy's Reeks to the south-west.
