It measures roughly 15 metres along a northwest to southeast axis, 5 metres across, and less than a metre in height. A large stone block, about 1.5 metres at its widest, sits at the southeast corner, and the tops of several other stones break through the turf above. What it actually is remains genuinely uncertain.

The mound was noted by archaeologists Ruaidhrí de Valera and Seán Ó Nualláin in their 1972 survey of megalithic monuments, where it appears catalogued under County Cavan as entry number seven. The term megalithic, meaning constructed using large stones, covers a broad family of prehistoric structures, including court tombs, portal tombs, and passage tombs, many of which were built in Ireland during the Neolithic period, roughly four to six thousand years ago. The trouble with this particular example is that its proportions and the arrangement of its stones do not clearly fit any of those categories. Whether it is a heavily degraded burial monument, a natural glacial feature that acquired some human modification, or something else entirely, the available evidence has not been enough to settle the question.
