In flat pastureland near Tully in County Galway, a hachured feature, the cartographer's shorthand for a depression or earthwork, appeared on the 1926 revision of the Ordnance Survey six-inch map and sat quietly unexamined for decades, the kind of anomaly that invites speculation simply by being recorded at all. When someone finally went to look in 1984, the reality was more modest: a hollow in the ground, the remnant of a disused gravel pit, probably worked sometime during the nineteenth or early twentieth century.

Gravel extraction of this kind was common across rural Ireland during that period, driven by the practical demands of road maintenance and farm drainage. Small pits were opened, used until the accessible material was exhausted, and then abandoned, leaving behind a slight scar in the landscape that grass and time gradually softened. What makes this one mildly notable is less the pit itself than its paper trail: the fact that it was captured on a map revision, given the visual weight of a hachured symbol, and thus inherited a kind of official ambiguity, sitting in the record somewhere between earthwork and excavation until a physical inspection settled the matter.
