On the 1920 edition of the Ordnance Survey six-inch map, the feature appears as a hachured marking, the small radiating lines surveyors used to indicate a depression or slope in the terrain. Without further context, such a marking can suggest something much older, the kind of earthwork that draws archaeologists and enthusiasts alike.

When the site was inspected in 1983, the feature turned out to be a quarry pit of post-1700 date, relatively recent by the standards of Irish field archaeology. Because it falls within the modern period, it lies outside the scope of archaeological classification, which generally concerns itself with sites predating AD 1700. Quarrying of this kind was common across rural Ireland in the eighteenth and nineteenth centuries, often carried out to extract limestone or other local stone for building, road-making, or agricultural lime production. What remains here is a pit in soft, marshy ground, more a footnote in the landscape than a monument, but one that spent decades wearing the ambiguous costume of something more ancient on a folded paper map.
