It sits on the townland boundary between Ballygeana and Carrigeen Mountain, in rough upland pasture, and its presence is now known almost entirely through historical cartography rather than anything a visitor could crouch down and touch. A boundary cairn is, in essence, a pile of stones deliberately heaped up to mark a territorial limit, the kind of practical, unloved monument that rarely attracted much attention even when it was intact.

The cartographic record of this particular cairn traces a quiet arc of diminishment. It does not appear at all on the first edition Ordnance Survey six-inch map of 1840, which suggests it was either overlooked by surveyors or had not yet been formally recorded. By 1897, the twenty-five-inch edition annotates the spot simply as 'Mound', a vague label that hints at something visible on the ground without committing to any interpretation. The later Cassini edition of the OSi six-inch map depicts it as a small circular mound, the kind of mark that implies a modest but legible feature in the landscape. By the time satellite imagery was analysed, between 2011 and 2013, no surface remains were visible at all. Two related boundary cairns survive nearby, one roughly 150 metres to the north-west and another around 190 metres to the east, and their presence confirms that this was once part of a deliberate sequence of markers running along the ridge.

Accessing the site means crossing open upland terrain, and the rough pasture noted in the records is the kind that demands boots rather than shoes. The ridge between Carrignabinnia and Slievecushnabinnia offers reasonable orientation, and the associated cairns to either side may be easier to locate than the central example, which has left no discernible trace on the surface. Compiled as part of a formal archaeological survey by Fiona Rooney and uploaded in November 2021, the record exists primarily as documentation of absence, a place where something once stood that is now recoverable only through the layers of mapping that, decade by decade, watched it disappear.
