The qualification matters: the site exists primarily as an arc of hachures on a 1914 Ordnance Survey six-inch map, and it is not visible at ground level. What was once legible to a surveyor as the curve of an earthwork has since been swallowed entirely, leaving the map as the only witness.

Hachures are short lines used by cartographers to indicate slope or raised ground, and when they appear in an arc on a period OS map, they typically suggest the remnant bank of a ringfort or similar enclosed settlement. Circular enclosures of this kind were common features of the early medieval Irish landscape, used variously as farmsteads, cattle enclosures, or places of local assembly. The 1914 map also records a trackway immediately to the north-west of the site, which hints that this corner of Cabragh was once navigated and used in ways no longer obvious from the ground. Cutaway bog, where the upper layers of peat have been removed, sometimes exposes earlier features but can just as easily obscure or destroy them, and in this case the enclosure, if it survives at all, remains buried or eroded beyond surface recognition.
