The Ordnance Survey's 1907 edition of the six-inch map records it in the understated italic lettering reserved for antiquities and curiosities, labelling it simply as a 'Pile of Stones'. That description, plain as it is, carried real legal and social weight. Boundary cairns were practical landmarks, built or adapted to mark the edges of townlands, the smallest unit of land division in the Irish administrative tradition, and disputes over where one townland ended and another began could carry serious consequences for grazing rights, taxation, and inheritance.

The cairn marked the line between Cortober to the south and Drumnafinnila Barr to the north. Whether it was constructed specifically for that purpose or was an older, repurposed feature pressed into service as a boundary marker is now impossible to say. What is certain is that by the time it was captured on the 1907 map, it was already being treated as a known, named feature of the landscape, significant enough to record, even if only in a handful of italic words. It is no longer extant. The stones are gone, dispersed or absorbed back into the ridge, and the boundary they once made visible on the ground is now traceable only through the map itself.
