Hachuring, a cartographic convention used to suggest slopes, hollows, and disturbed ground, marked this spot as something worth noting, though the map offered no further explanation. When someone finally went to look in 1983, the feature turned out to be a disused quarry, almost certainly worked at some point after 1700.

That date matters in a particular way. Because the quarry falls within the post-medieval period, it sits just outside the scope of formal archaeological classification in Ireland, which tends to focus on earlier remains. The result is a place that was significant enough to leave a mark on a map, was investigated and identified, and then effectively filed away. Quarries of this kind were once common across rural Ireland, cut into hillsides to extract stone for field walls, farmhouses, and road surfacing. Most have no documentation beyond the scar they left in the ground.
