This one exists almost entirely as a ghost in aerial photography, a small circular mark in reclaimed wet pasture in County Limerick that has left no trace a walker could detect underfoot. It is a ditch barrow, a type of prehistoric burial monument defined by a circular enclosing ditch rather than a raised mound, and its diameter here is approximately four metres. The Ordnance Survey never recorded it on historic maps, and between 2011 and 2013 a Digital Globe orthoimage showed nothing at the surface at all. What keeps it in the archaeological record is essentially a shadow in a crop.

The site came to light not through excavation or fieldwork but through an unlikely administrative exercise. When Bórd Gáis Éireann was planning a gas pipeline, aerial photographs were taken across the relevant corridor on 3 November 1984, at a scale of 1:5,000. Analysts examining those images noticed a circular feature in the fields near Ballinvana, in the area bounded to the east by the Morningstar River, which marks the townland boundary with Elton, and to the north by the boundary with Stephenstown. The monument sits roughly 45 metres west of that river and 55 metres south of the northern boundary. It is the most northerly of six possible barrows in the vicinity, all of which may form part of a wider possible field system, suggesting the landscape here was organised and used over a long period. A later Google Earth orthoimage taken in September 2019 confirmed the circular cropmark, and also showed a linear cropmark intersecting it from the west, possibly a drainage ditch running northeast to southwest, which complicates any reading of the feature's original extent.

Cropmarks appear when buried features affect how vegetation grows above them, with ditches often producing lusher, greener growth that becomes visible from the air, particularly during dry summers when the contrast is sharpest. There is nothing here for a visitor to see from ground level; the reclaimed pasture gives no indication of what lies beneath. The value of the site is archival and interpretive rather than visual, a reminder that a significant number of Irish monuments exist only in the record of what a camera caught from altitude on a particular November afternoon four decades ago. The compiled record was uploaded to the national monuments database by Fiona Rooney in June 2021, and it is there, rather than in the field, that this particular barrow can be most usefully encountered.
