Hachures, the short radiating lines cartographers use to suggest slopes or depressions in the landscape, indicated something worth noting. When someone finally went to look in 1984, they found not a monument or an earthwork of ancient significance, but a disused gravel pit, its outline softened almost to invisibility by dense vegetation.

The pit dates to after 1700, which places it firmly in the era of agricultural improvement and local industry rather than prehistory. Gravel extraction of this kind was commonplace in rural Ireland, used for road surfacing, drainage work, and construction. What remains today is essentially a depression in a field, overgrown enough that it reads more as a hollow in the ground than any obvious sign of former industry. The 1944 to 1945 map revision that first flagged the feature was part of a broader national effort to update Ordnance Survey coverage across Ireland, and it captured this small landscape scar at a moment before vegetation had entirely swallowed it.
