Roughly 31 metres north to south and 21 metres east to west, it sits unobtrusively in farmland, the kind of feature that most walkers would pass without a second glance. What makes it worth pausing over is precisely the uncertainty surrounding it: the hollow may be the remains of a post-1700 quarry, or it may be something else entirely, and the record is careful not to overstate the case either way.

The feature does not appear on the first edition Ordnance Survey six-inch map of 1840, which is itself a small piece of evidence. By the time the 25-inch edition was surveyed and published in 1897, however, the sunken oval had been noted and mapped. That gap in the cartographic record suggests the feature either came into being or became prominent enough to record somewhere in the intervening decades, which would be consistent with a post-1700 quarrying episode. Some 45 metres to the north lies a separate feature recorded as a possible enclosure, one of those ambiguous earthworks that crop up across the Irish countryside and may represent anything from a ringfort to a garden boundary to a field system of uncertain age. A linear cropmark, visible running east to west and intersecting the oval depression, adds a further layer of complexity. Cropmarks appear when buried features affect the growth of surface vegetation, and they can indicate walls, ditches, or disturbed ground lying just beneath the soil.

The site sits around 190 metres east of the townland boundary with Knockaunacurragha, which helps with orientation if you are working from a map. It is not signposted and there is no formal access; this is agricultural land, and any visit would require landowner permission. The earthwork itself is most clearly visible in aerial or satellite imagery, and both Digital Globe orthoimages from 2011 to 2013 and a Google Earth image dated November 2018 show the depression and its intersecting cropmark with reasonable clarity. For those with an interest in how the landscape records its own history in subtle, sometimes illegible ways, this is exactly the kind of site that rewards close looking rather than quick conclusions.
