Hachuring, the short radiating lines cartographers used to indicate slopes or depressions, suggested something sunken into the landscape, something worth a second look. When that second look finally came, in 1984, the feature turned out to be an irregularly shaped, tree-filled hollow, most likely the remains of a disused quarry. By that point the trees had long since moved in, softening whatever sharp edges the original digging had left behind.

Because the site dates to after AD 1700, it falls outside the scope of archaeological protection in Ireland, which generally concerns itself with features from earlier periods. That cut-off is a reminder of how recently much of the Irish landscape was actively worked for stone, with small local quarries supplying material for field walls, roads, and buildings before industrialised extraction made them redundant. The quarry at Eskerboy left no dramatic scar, only a hollow in the ground and a canopy of trees where once there may have been the sound of chisels.
