Roughly 21 metres east to west and 14 metres north to south, rising to about 1.8 metres, it is grassed over and in fair condition, with occasional stones pushing through the soil. What makes it genuinely peculiar is the natural well enclosed by a drystone wall sitting within the mound's western half, a combination that does not fit neatly into any single category of archaeological feature.

The mound's classification has remained a question mark for decades. A 1952 study by McCaffrey recorded it tentatively as a tumulus, the Latin term used in archaeology for a burial mound, though without any certainty that this is actually what it is. The 1838 edition of the Ordnance Survey six-inch map, one of the earliest systematic cartographic records of the Irish landscape, shows the site not as a mound at all but as an unenclosed tree-ring, suggesting that whatever the feature looked like or was understood to be in the mid-nineteenth century, it was not yet being read as an ancient monument. It may simply be a landscape feature of some kind, shaped by agricultural or drainage activity over centuries, with the well predating, postdating, or entirely unrelated to the earthwork around it. The presence of both elements together is the kind of ambiguity that the Irish landscape specialises in.
