It does not appear on the Ordnance Survey Ireland maps that documented much of the island's landscape in painstaking detail. It is not visible on satellite imagery, including a Google Earth orthoimage captured as recently as June 2018. The only reason it is known to exist at all is because a low-flying aircraft happened to pass over it in 1986.

That aerial survey, the Bruff photographic survey of 1986, recorded the site under the reference Bruff 250 AP 4/3740. The image revealed a roughly circular enclosure with an external diameter of approximately 35 metres. An enclosure of this type is broadly understood as a defined area bounded by an earthwork, bank, or ditch, which in Irish archaeology often indicates early medieval settlement or agricultural activity, though without excavation the precise function remains unknown. Three sides of the enclosure, the northern, eastern, and southern arcs, are reasonably legible in the aerial photograph. The western side is considerably less distinct, suggesting either partial collapse or differential crop and soil response that the camera did not catch clearly. The site sits about 25 metres west of the townland boundary with Pust South. A ringfort, a related but separately recorded type of circular earthwork enclosure, lies around 160 metres to the northeast, and further enclosures have been recorded approximately 200 metres to the southwest, suggesting this pocket of Limerick farmland once held a cluster of activity that has since sunk almost entirely beneath the pasture. The record was compiled by Edmond O'Donovan and uploaded to the Sites and Monuments Record in September 2020.

Because the enclosure is invisible at ground level and does not register on current satellite images, there is little a visitor can expect to see in the conventional sense. The value here is conceptual as much as anything else: standing on ordinary-looking pasture and knowing that the outline of something old was once legible from above, even if it has since disappeared from view entirely. The Bruff survey image, referenced in the monument record, remains the clearest evidence of its existence. Those with a particular interest in aerial archaeology or the Sites and Monuments Record database may find it worth cross-referencing the surrounding cluster of monuments, given how closely this enclosure sits to its recorded neighbours.
