Sitting about 135 metres west of a watercourse that still serves as the boundary between the townlands of Kilgarriff and Ahnaguarra, this earthwork is the kind of feature that rewards a second look. A scarp, meaning a short but distinct slope in the ground surface, defines its edge and gives it a raised, platform-like quality. Its diameter is approximately 24 metres, making it a modest but clearly intentional piece of shaping in the landscape.

The site appears on the first edition Ordnance Survey six-inch map of 1840, where it is recorded as an oval-shaped area defined by that scarp. By the time the 25-inch edition was produced in 1897, its outline had shifted slightly in description, appearing as a raised, roughly circular form, and the scarp itself had been absorbed into a field boundary, the kind of practical reworking of ancient features that happened routinely as agricultural land was enclosed and reorganised across rural Ireland. A related enclosure, a separately recorded monument, lies about 200 metres to the southwest, suggesting this part of Kilgarriff once held a more complex arrangement of features than what survives today. The record was compiled by Martin Fitzpatrick and uploaded to the national monuments database in November 2021.

On recent satellite imagery, including Digital Globe orthoimages taken between 2011 and 2013 and images available via Google Earth, the earthwork shows up clearly as a circular area picked out by trees, which have grown along or near the old scarp line. This tree cover is, in a practical sense, what makes the feature legible from above and likely what has helped protect it from more intensive ploughing or levelling over the years. On the ground in a working pasture, it would be easy to overlook without knowing what to look for; the rise is subtle, and the boundary between the earthwork and the surrounding field is softened by grass and time. The nearby watercourse and the tree ring remain the clearest navigational anchors for anyone approaching the site.
