It was not recorded by any surveyor walking the land; instead, it was spotted from the air. That absence from the official cartographic record is itself telling, suggesting that whatever once rose or sank here had already been absorbed so thoroughly into the agricultural landscape that ground-level observation simply passed it by.

The site at Coolscart was identified as a possible barrow during the Bruff aerial photographic survey in 1986, catalogued as Bruff 68 (AP 5/2076). A ditch-barrow, for those unfamiliar with the term, is a prehistoric funerary monument defined not by a raised mound but by a surrounding fosse, or ditch, which in some cases would originally have enclosed a low central platform. The circular shape defined by that fosse became legible again on Ordnance Survey orthophotos taken between 2005 and 2012, and is also traceable on Google Earth imagery, where the feature sits immediately north of a drainage ditch running northeast to southwest. A separate earthwork, recorded as LI040-029, lies roughly 90 metres to the west, hinting that this small corner of Limerick may have held more significance in the prehistoric period than the surrounding farmland now suggests. The record was compiled by Martin Fitzpatrick and uploaded in June 2021.

Because the site lies within reclaimed agricultural pasture, there is no formal public access, and nothing dramatic marks the spot for a visitor scanning the field. The barrow's outline is most readily appreciated through aerial or satellite imagery rather than on foot. Those interested in visiting the broader area should be aware that a watercourse runs approximately 90 metres to the south, and the land is actively farmed. If you do examine the Google Earth orthoimages before going, the drainage ditch running diagonally across the field provides the clearest orientation point; the faint circular shadow of the fosse sits just to its north, easy to miss unless you already know what you are looking for.
