There is nothing to see at ground level, no ridge or hollow, no trace of a bank or ditch. The field looks like a field. And yet the site is recorded, classified, and mapped, because for one brief window in 1973, an aircraft flying overhead caught something that the ground itself no longer shows.

What gave the site away was a cropmark, the faint but legible signature that buried archaeological features can leave in growing vegetation. When soil has been disturbed by old ditches or foundations, it retains moisture differently from the surrounding ground, and in dry conditions those differences become visible from above as variations in crop colour and growth. The aerial photographs taken in 1973, held by the Geological Survey of Ireland Air Photography collection, captured just such a mark here, indicating a monument that has since been levelled flat. By 1983, a field visit found nothing discernible at all; the site was under a heavy crop of hay, and even with that allowance, there were no features of archaeological interest to report. The earthwork does not appear on any Ordnance Survey historic maps, which suggests it had already been reduced or obscured before systematic cartographic recording began, or that it was simply never substantial enough to attract a surveyor's attention. Its presence about twenty metres north of a field boundary running roughly east-northeast to west-southwest is the closest thing to a precise location that the record offers.
