What remains visible tells only part of the story: a single flat stone slab, measuring about 1.7 metres by 1 metre and nearly half a metre thick, resting on a submerged pile of stones. The structure beneath the peat is subrectangular in outline, running roughly 20.5 metres on its longer axis and about 8 metres across, with an exposed height of around a metre. No kerbstones, the upright or flat stones that would typically edge and define a cairn's perimeter, can be made out at the surface.

Cairns of this kind are among the older monuments in the Irish landscape, generally understood as burial or ceremonial structures raised during the Neolithic or Bronze Age periods. The peat that obscures this one is both a concealer and a preserver; bog conditions are famously effective at protecting organic and stone material from decay, which means that what lies beneath the surface here may be considerably more intact than it appears from above. The plateau setting, overlooking the Glenaniff valley to the north, suggests a deliberate placement, perhaps chosen for its visibility across the valley or its relationship to the wider landscape, though the monument's purpose and precise date remain unknown from what survives above ground.
