Hachures are short lines used by cartographers to suggest slopes or surface irregularities, and on a map of that era they could indicate anything from a natural hollow to a worked cutting. For nearly four decades, this particular feature remained just that, an unverified symbol on ageing paper.

When the site was inspected in 1983, the feature resolved itself into something more specific: a quarry. Small rural quarries like this one were once commonplace across Ireland, typically worked to extract stone for local field walls, road surfaces, or building material for nearby farms and cottages. They rarely attracted documentation and were often abandoned once local demand was satisfied or a more convenient source found. What makes this example quietly interesting is the gap between its appearance on a mid-century map and its eventual identification on the ground, a reminder that even modest features in the Irish landscape can carry a small ambiguity until someone actually walks out to look.
