It is not a standing stone or a carved slab that was moved and placed; the mark is made on a natural outcrop, as if whoever made it was claiming the hillside itself rather than erecting anything upon it. The Latin cross, a form with arms of equal or near-equal length, is deeply incised into the eastern face of the outcrop, measuring roughly 24 centimetres high and 20 centimetres wide, with rounded terminals at the end of each arm. Small in absolute terms, but deliberate and assured in execution.

Cross-inscribed rocks of this kind are found across Ireland and are generally associated with early medieval Christianity, roughly the period between the sixth and twelfth centuries, when the marking of landscape features with simple crosses served purposes that could range from devotional to territorial. Placing such a mark on a prominent outcrop on a hillside may have indicated a boundary, a place of prayer, or a point along a route with religious significance. The eastern orientation of the incised face is worth noting; east-facing carvings and east-facing altars share a long association in Christian practice with the direction of sunrise and resurrection. The rounded terminals distinguish this cross from plainer, more austere cuts and suggest a maker with some awareness of the decorative conventions of the period, even if the work itself is modest in scale.
