It measures 1.9 metres across and half a metre thick, its long axis oriented northeast to southwest, and it has the particular quality of prehistoric standing stones everywhere: no label, no obvious explanation, just presence.

What makes the site more than a solitary monument is what sits immediately to its southwest. Two boulder-burials lie close by, a type of monument found almost exclusively in southwest Ireland, in which a large capstone rests directly on the ground or on low supporting stones, covering a burial deposit beneath. The clustering of a standing stone with boulder-burials is not accidental. These groupings suggest that the landscape around the upper Ihernagh was treated as a significant ceremonial or funerary zone during the Bronze Age, with different monument types accumulating in the same spot over time, or perhaps erected together as part of a single commemorative act. The flat, open ground around the river's headwaters would have made the standing stone visible from a considerable distance, which may well have been the point.
