That is partly because the marks are deeply weathered, some faded almost to nothing, and partly because the boulder has long since been pressed into service as part of a field boundary wall, its prehistoric purpose quietly absorbed into the everyday geometry of a working landscape. What survives on its sloping face, across a decorated area roughly 1.3 metres by 0.9 metres, is a dense and still only partially legible arrangement of prehistoric rock art, the kind found across upland Kerry and elsewhere in Atlantic Europe, and dated broadly to the Later Neolithic or Early Bronze Age.

The centrepiece of the design is a cruciform motif, about 45 centimetres across, formed by seven equilateral shafts radiating outward from a single point, each one terminating in a cup-and-ring or partial cup-and-ring. Cup-and-ring marks are among the most common motifs in prehistoric rock art, consisting of a small circular depression, the cup, enclosed by one or more carved concentric rings. Here the cruciform arrangement of those terminals gives the whole composition an unusual, almost wheel-like character. To its south-east sits a keyhole motif, a form in which a cup mark and its surrounding ring are joined to an elongated groove, producing a shape resembling a keyhole in outline. This feature, measuring roughly 25 by 19 centimetres, is particularly weathered, and may have suffered additional damage from freeze-thaw action over the centuries, water expanding in the carved grooves and gradually widening the fractures in the sandstone. Other grooves and cupmarks are distributed across the boulder's surface, though many are now too faint to read with confidence. A. O'Sullivan and J. Sheehan documented the full design in their 1996 archaeological survey of the Iveragh Peninsula, and subsequent fieldwork has confirmed that some of the features they recorded have since deteriorated further.

The boulder sits at roughly 138 metres above sea level on an east-facing slope, with views across the River Behy valley and towards a sweep of mountains including Beenreagh, Macklaun, Knocknaman, Coomreagh, and Drung Hill. A grass-covered trackway runs immediately to the east of the stone. The combination of elevation, outlook, and elaborate carving suggests this was not an incidental spot, though what the carvings meant to the people who made them remains, as with nearly all prehistoric rock art, genuinely unknown.
