Hachuring, the technique of using short radiating lines to indicate a hollow or depression in the landscape, was the cartographer's way of saying something was there, even if its exact nature was uncertain. By the time anyone went to look more closely, in 1984, nothing remained to be seen. A silage pit had taken over the site, and whatever had once shaped the ground into something worth recording was gone, or at least invisible.

What the original feature actually was remains a matter of cartographic inference. The evidence points toward either a quarry pit, the kind of small working extraction that was commonplace across rural Ireland in the post-medieval period for sourcing limestone, gravel, or building stone, or simply a natural depression in the land. Either way, it post-dates AD 1700, which places it in the relatively recent agricultural past rather than in the deeper layers of Irish prehistory. The gap between the map and the visit on the ground is itself telling: roughly four decades separated the recording of the feature and the inspection that found it gone, replaced by the functional demands of a working farm.
