Hachuring on maps of that period typically signals a slope or earthwork of some kind, something the cartographers considered worth recording. When the site was physically inspected in 1984, the feature turned out to be a disused limestone quarry, the kind of small, localised extraction pit that once supplied the raw material for an entire agricultural economy.

The quarry almost certainly fed the limekiln that stands roughly 300 metres to the south-west. A limekiln is a stone-built furnace in which limestone was burned at high heat to produce quicklime, used widely from the eighteenth century onwards to dress acidic soils and improve agricultural yields. The pairing of a small quarry and a nearby kiln was a common arrangement across rural Ireland during this period: the stone came out of the ground at one point, was burned a short walk away, and the resulting lime was spread across the surrounding fields. Because the quarry dates to after 1700, it falls outside the scope of formal archaeological classification, which tends to focus on earlier remains, but that administrative boundary should not suggest the site is without interest. It is a legible trace of the way ordinary farming communities organised their land and their labour.
