Hachures, the short radiating lines cartographers used to indicate slopes or depressions, suggested something worth noting at the time of survey. When someone finally went to look in 1984, the feature turned out to be a hollow in the ground, most likely the remains of a disused quarry. It is a small and unspectacular thing, and that, in its own way, makes it quietly interesting.

The gap between the map and the inspection spans nearly four decades, and the conclusion reached was modest: probably a quarry, probably post-1700, and therefore too recent to fall within the scope of archaeological recording, which in Ireland generally concerns itself with sites predating that threshold. The working life of such a quarry, wherever it fits in the post-medieval period, would have been entirely ordinary, supplying stone for field walls, farmhouses, or road repairs in the surrounding landscape. What remains is simply a hollow where extraction once happened, the kind of feature that accumulates slowly on maps and then waits, sometimes for a very long time, for anyone to come and check.
