On the 1920 edition of the Ordnance Survey six-inch map, the feature appears as a hachured marking, the fine radiating lines surveyors used to indicate a depression or slope in the terrain. It looked, on paper, like something worth noting. When someone finally went to look in person, in 1983, the reality was more prosaic: a disused gravel pit, its outline traced by an irregular depression in the earth.

Gravel pits of this kind were a routine part of rural infrastructure throughout the post-medieval period. Locally dug gravel served roads, farmyard surfaces, and building work, and such pits were opened and abandoned as need dictated, leaving little behind except a dip in a field. Because this one post-dates AD 1700, it falls outside the scope of formal archaeological classification, which in Ireland generally concerns itself with the more distant past. The 1920 map entry is in some ways the most interesting thing about it, a reminder that Ordnance Survey cartographers recorded the visible landscape without always knowing precisely what they were capturing, and that the gap between a mark on a map and the thing it represents can take decades to close.
