That absence is its most immediately curious quality. The mound stretches 61.2 metres in length, roughly 14 metres across at its base, and rises only about 0.4 metres above the surrounding ground, a low, almost reticent presence in a field that is, by all accounts, poor grazing land.

The site at Carhooearagh was documented as part of the North Kerry Archaeological Survey, published in 1995 under the authorship of C. Toal. Beyond its dimensions and general setting, the record is spare. What the mound represents, whether a buried field boundary, a long barrow of prehistoric origin, or something else entirely, is not stated. Long earthen mounds of this kind can serve very different purposes across Irish archaeology, from Bronze Age funerary monuments to much later agricultural or boundary features, and without excavation or further investigation it is difficult to assign this one to any particular tradition with confidence. The landscape around it, low-quality pasture in a part of Kerry that does not attract the same volume of archaeological attention as more celebrated regions, may be part of why so little follow-up work appears to have been carried out.
