The larger of the pair stands about a metre high, leans slightly towards the east, and is oriented along a north-south axis. The smaller stone, only thirty centimetres above the ground, sits about one and a half metres to the east. The hollow in which they both rest gives the arrangement a faintly deliberate quality, as though the ground itself was shaped around them, though whether by human hands or by natural processes is not clear.

What makes the location particularly interesting is the proximity to a wedge tomb just under eight metres to the south-east. A wedge tomb is a megalithic burial monument, typically dating from the late Neolithic or early Bronze Age, built from large stone slabs and narrowing in width and height from one end to the other. Their presence across the Irish landscape is well documented, but the significance of standing stones or stone groupings found in close association with them is less well understood. Whether the two stones at Crinnaloo were erected as part of the same ritual landscape as the nearby tomb, or arrived there independently at a different period, remains an open question. It is precisely that ambiguity that earns them the designation anomalous, a label that is less a dismissal than an honest admission of what is not yet known.
