On the 1944 to 1945 revision of the Ordnance Survey six-inch map, the feature appears marked with hachures, the fine radiating lines draughtsmen used to indicate a hollow or slope, suggesting something worth noting but not fully explained. It was not until 1984 that an inspection on the ground settled the matter: the feature is a disused quarry, most likely worked at some point after 1700.

That post-1700 date is not a minor administrative detail. It places the quarry outside the scope of archaeological protection, which in Ireland generally concerns itself with sites predating that threshold. Quarries of this period were a routine part of rural life, cut into local rock to supply stone for field walls, farm buildings, and roads, and then quietly abandoned when the need passed or the stone ran out. Without further investigation it is impossible to say what was extracted here, or who worked it, or when it fell out of use. What remains is a modest earthwork in a field, easy to overlook, its origin confirmed only after the map had been quietly marking it for nearly forty years.
