Measuring approximately 15 metres across and standing 3.5 metres high, this grass-covered feature appears to be partly natural, partly constructed; a collaboration between geology and human hands. First documented in the OS Revision Name Book of 1848, it has intrigued archaeologists for generations.

The site's archaeological significance was noted by Colhoun in 1949, who classified it as a 'multi-chambered cairn or dolmen', though its exact nature remains somewhat mysterious. The mound consists of accumulated stones, now overgrown with grass, blending into the surrounding landscape of low rock formations that characterise this part of north Donegal. Whether it served as a burial monument, ceremonial site, or had another purpose entirely continues to be a matter of scholarly debate.

Various surveys and archaeological inventories have recorded the monument over the years, including entries by Killanin and Duignan in the 1960s and its inclusion in the Sites and Monuments Record in 1987. The Survey of the Megalithic Tombs of Ireland, compiled by Eamon Cody in 2002, provides the most recent formal description, though the site's partly natural formation makes it difficult to determine its original extent and construction. Today, it remains an enigmatic feature of the Donegal landscape, a reminder that not all ancient monuments yield their secrets easily.
