The Ordnance Survey six-inch map, revised in 1944 and 1945, carries a hachured marking at this spot, the kind of notation cartographers used to indicate a rise or hollow in the terrain. For decades, that symbol sat unexplained on the map, a minor question mark in the landscape.

When the site was inspected in 1984, the feature turned out to be a disused limestone quarry, its former activity now reduced to a scatter of bumps, hollows, and limestone boulders. Limestone quarrying of this kind was commonplace in rural Ireland from the eighteenth century onwards, with local stone extracted for building, for road repairs, and for burning in lime kilns to produce agricultural lime that sweetened acidic soils. Because this quarry dates to after AD 1700, it falls outside the formal scope of archaeological classification in Ireland, which generally concerns itself with earlier remains. That boundary is not a judgement on the site's interest, only a bureaucratic threshold, and it means the quarry exists in a quiet gap between the historical and the archaeological record.
