On the 1944 to 1945 revision of the Ordnance Survey six-inch map, the spot was marked with hachures, the short radiating lines that surveyors use to indicate a slope or surface irregularity. It was the kind of mark that could mean many things, and for nearly forty years it remained unverified on the page.

When someone finally went to look in 1984, the feature turned out to be a disused quarry. Small rural quarries of this kind were once commonplace across Ireland, cut into convenient outcrops to supply local farms and estates with stone for walls, buildings, or road repairs. Because this one dates to after 1700, it falls outside the scope of archaeological protection, which in Ireland generally concerns itself with features from earlier periods. That single fact, almost administrative in tone, quietly places the quarry in a particular band of history: recent enough to be considered industrial or agricultural heritage rather than archaeology, old enough to have gone entirely out of use and been half-forgotten beneath the grass.
