What appears on an Ordnance Survey map from the 1944 to 1945 revision as a hachured feature, the cartographic shorthand for a depression or earthwork of some kind, was investigated in person in 1984 and found to be nothing more, and nothing less, than a small disused quarry. The gap between map symbol and ground truth is a neat reminder of how much ambiguity can be encoded in a single surveyor's mark.

The quarry dates to after 1700, which places it firmly in the era of improving landlords, estate building, and the steady demand for local stone that accompanied both. Small quarries of this kind were common across rural Ireland, opened to supply material for field walls, farmhouses, or estate infrastructure, and quietly abandoned once the immediate need was met. Because this one falls within the post-medieval period, it sits outside the scope of prehistoric and early historic archaeology, which is why it occupies an unusual administrative position, noted and inspected, but not quite belonging to any formal canon of monuments.
