The outline measures roughly 22 metres across internally, and the wall, where it can still be made out, averages about 65 centimetres wide, enough to suggest deliberate construction rather than field clearance or natural scatter. What makes this particular feature quietly compelling is its uncertainty. The word "possible" hovers over it: it may be an enclosure, the kind of roughly circular or oval boundary wall that would have defined a domestic or agricultural space in early medieval Ireland, but the surviving evidence is too fragmentary to say so with confidence.

A short distance to the south-west of a related site also recorded in Canearagh, this semicircular remnant was documented as part of a comprehensive archaeological survey of the Iveragh Peninsula compiled by A. O'Sullivan and J. Sheehan and published by Cork University Press in 1996. The survey catalogued the remarkable density of archaeological remains across this part of Kerry, a landscape that has preserved evidence of human activity across many centuries partly because it was never heavily industrialised or intensively redeveloped. The boulders at Canearagh represent one of the more ambiguous entries in that record, a site where the physical remains have been reduced to a faint arc, and interpretation depends as much on what is absent as on what survives.
