On the 1945 revision of the Ordnance Survey six-inch map, it appears as a hachured feature, the small radiating lines cartographers use to suggest a depression or earthwork in the landscape. To anyone reading that map, it might easily have passed for something ancient, perhaps a collapsed structure or a feature of archaeological interest.

When the site was inspected in 1984, the reality turned out to be more modest. The hollow was irregular in shape and almost certainly the remains of a disused quarry, the kind of small local extraction site that once supplied stone for field walls, farmyard buildings, or road repairs across rural Ireland. Because it dates to after AD 1700, it falls outside the scope of formal archaeological classification, which in Ireland generally concerns itself with earlier remains. That boundary is a useful reminder of how recently much of the visible Irish countryside was actively worked and reshaped, and how easily the evidence of that labour can look, from a distance or on a map, like something far older.
