On the Ordnance Survey 25-inch map it is labelled simply as a quarry. Yet the same feature, rendered with hachures on the 1939 edition of the OS map, was later recorded as a possible enclosure, which in Irish archaeological terms typically refers to a roughly circular earthwork demarcating a settlement, ritual, or boundary space.

The discrepancy first surfaced formally when the feature was entered into the Sites and Monuments Record in 1992 and again in the Record of Monuments and Places in 1996, each time with the cautious qualifier "possible". Hachures on older Ordnance Survey maps indicate a raised or banked outline, the kind of marking cartographers used for earthworks they could see on the ground. The trouble is that a quarry worked in a roughly circular fashion, or one cut into an older earthwork, could easily produce the same visual signature on a map. Without excavation or detailed survey, there is no reliable way to settle the question from the record alone. It is the sort of ambiguity that turns up regularly in the Irish archaeological inventory, where centuries of land use have blurred the distinction between what humans built deliberately and what they extracted, levelled, or repurposed afterwards.
