Described as one of the most isolated rock art sites in the country, it is the kind of place that demands considerable effort to reach before it offers anything in return. What it offers, once found, is a rough, fractured surface roughly 2.72 metres by 1.65 metres, carrying around fifty cupmarks and four cup-and-ring motifs, all carved at some point during the prehistoric period, most likely the Bronze Age.

Cupmarks are exactly what the name suggests: shallow, roughly circular depressions hammered or ground into stone, whose original purpose remains genuinely unclear. Cup-and-ring motifs add one or more concentric rings around the central cup, and occasionally a groove radiating outward from it. On this boulder, the motifs vary considerably in scale and character. One cup-and-ring is just four centimetres across in its entirety, barely larger than a thumbnail. Another features a ring formed not from a continuous groove but from a series of individual pickmarks arranged in an arc. Four pairs of cupmarks on the eastern end of the surface form two parallel lines, a degree of deliberate arrangement that stands out even among the denser, less ordered scattering elsewhere. Part of the decorated surface is now hidden under peat and sod, and some linear elements recorded in a 1996 survey of the Iveragh Peninsula by A. O'Sullivan and J. Sheehan are no longer visible, lost either to erosion or to creeping ground cover.

The site sits between Broaghnabinnia to the north and the Knocklomena mountains to the south, overlooking the Gearhameen river to the south-east, though not in any direct or commanding way. The boulder occupies mountain heath, tucked into the landscape rather than marking it. Whatever the carvers intended by placing their work here, legibility from a distance was clearly not part of it.
