What makes it quietly interesting is precisely what nobody can say for certain: this feature does not appear on any of the historic Ordnance Survey Ireland maps that have long served as the baseline record for earthworks and monuments across the Irish countryside. Its existence went unregistered until aerial photography caught it from above.

The site came to attention through the Bruff aerial photographic survey of 1986, in which it was catalogued under the references Bruff 131.01 and 130.02. Aerial survey of this kind, in which low-level oblique or vertical photographs are examined for cropmarks, soil marks, and subtle variations in ground surface, has been one of the most productive tools for identifying features that ground-level fieldwork misses entirely. A separate field bank runs east to west along the northern side of the feature. The circular form and surrounding bank were subsequently confirmed visible on Ordnance Survey orthophotos taken between 2005 and 2012, and again on a Google Earth image dated 20 September 2020, suggesting the depression has remained stable and legible from the air across several decades. Researchers have noted, however, that the earthworks may not be archaeological in origin at all. The current assessment, compiled by Martin Fitzpatrick and uploaded in April 2021, raises the possibility that what looks like a monument could instead be the result of post-medieval quarrying, a not uncommon source of circular or scooped depressions in Irish farmland where stone or gravel was extracted for local use.

The feature sits in working pasture, so access would depend entirely on landowner permission. Because the earthwork is most clearly defined from above, ground-level inspection offers less than aerial or satellite imagery can. Visitors curious about what they might actually see on foot should expect a grassed-over depression with a low surrounding rise, most legible in low winter light when vegetation is short and shadows pick out slight changes in relief. The ambiguity of the site is, in some ways, the point: it is a reminder that not every mark in the Irish landscape resolves neatly into a ringfort or a rath, and that the gap between a quarry hollow and a monument can be genuinely difficult to close.
