The site is known only because a surveyor recorded it on the Ordnance Survey's six-inch map in 1838, using hachures, the short parallel lines that cartographers of the period used to indicate earthworks and raised ground. By the time the trees came, whatever had once made these enclosures legible at ground level had already gone, leaving behind nothing more than a cartographic ghost.

The enclosures are described as conjoined, meaning the two roughly circular forms share a boundary or overlap, giving the combined footprint an approximate measurement of thirty metres by eighteen. Circular enclosures of this type are among the most common archaeological features in the Irish landscape, and they span an enormous range of dates and functions, from prehistoric settlement enclosures and early medieval ringforts to stock enclosures of much later periods. Without excavation, it is not possible to say which category these belong to. What the 1838 map does confirm is that they were detectable on the surface at the time of the first systematic mapping of Ireland, on a gentle south-east facing slope that presumably offered some shelter and usable ground before the forestry changed the character of the place entirely.
