In the upper reaches of the Ox Mountains in County Sligo, on the boundary between Carrownamaddoo and Cloonagh townlands, one such structure was recorded and then quietly reassessed. The conclusion was a deflating one: it was probably a relatively modern boundary marker rather than a genuine antiquity.

The site's doubtful credentials were compounded by its absence from the 1837 edition of the Ordnance Survey six-inch map, one of the most thorough cartographic undertakings of nineteenth-century Ireland and a standard reference point for distinguishing older features from later ones. A structure not recorded by that survey, sitting precisely on a townland boundary, fits the profile of something practical and recent rather than prehistoric. The stones have since been removed entirely, leaving no physical trace on the ground.
