A hachured area, the cartographic shorthand used on Ordnance Survey sheets to indicate a slope or earthwork, can suggest an ancient enclosure, a natural feature, or something else entirely, and it takes a site visit to settle the question. On the southern slope of a low hill in the undulating pastureland of Cloonkeen Eighter, such a marking appeared on the 1931 edition of the six-inch OS map, quietly inviting speculation about what lay beneath the notation.

When the site was inspected in 1985, the answer turned out to be modest but instructive. The feature was not a rath, not a collapsed souterrain, not anything ancient. It was a depression left behind by quarrying operations, the kind of working that once supplied local farms and townlands with stone for field walls, road surfaces, or building foundations. These small, informal quarries were once common across the Irish countryside, often dug out over generations and then simply abandoned when the material ran out or the need passed. They rarely made it into historical records in any meaningful way, which is part of why the gap between a mark on a mid-twentieth-century map and a confirmed identification on the ground took over fifty years to close.
