What looks from a distance like an unremarkable dip in the terrain is, in fact, all that remains of a disused quarry, the kind of working site that once supplied local stone for building and was then gradually reclaimed by vegetation once the need for it passed.

The quarry first appeared as a hachured feature on the 1933 edition of the Ordnance Survey six-inch map, the hachuring being a cartographic convention used to suggest changes in ground level or surface irregularity. It was not until 1983 that someone went to look at it properly, at which point the feature resolved itself into the overgrown hollow of an abandoned quarry. Because the site dates to after 1700, it falls outside the timeframe that governs archaeological classification in Ireland, which generally concerns itself with earlier remains. That boundary is not a judgement on significance so much as a practical division between archaeology and industrial or post-medieval history. Quarries of this period were commonplace across rural Ireland, dug to extract limestone, sandstone, or other local materials for field walls, farmhouses, and roads, then left once the immediate need was met.
