The structure is a cist, a type of prehistoric burial chamber formed by setting upright slabs on their edges to create a rectangular enclosure, then sealing the whole thing with a capstone. This one measures roughly 1.55 metres east to west and 0.58 metres north to south, just large enough to have contained a crouched or cremated burial. It is damaged, and the damage appears deliberate.

The cairn in which the cist sits, a mound of stones heaped over the burial to mark and protect it, has itself been disturbed. On either side of the cist are loose heaps of stone, most likely the material thrown aside by whoever dug down through the cairn's centre to reach the chamber beneath. A single slab now lies flat on the ground immediately to the north-west of the cist; this may well be the capstone, levered off and discarded once whatever lay inside had been removed or examined. Whether that intrusion happened centuries ago or relatively recently is unclear. Elizabeth Gills documented the site and reported it to the National Monuments Service in 2006, which is when it entered the formal record.
