The cairn, a mound of stones or earth heaped over a megalithic burial chamber, is often what survives most visibly at prehistoric sites; its absence here gives this tomb an exposed, skeletal quality, the bones of a structure whose outer body has long since disappeared.

The tomb sits on the northern bank of a stream running east to west, with rock outcrop breaking through the ground just to the west. Its chamber is aligned on a northwest to southwest axis. The only cartographic record to name it as anything at all appears on the 1907 edition of the Ordnance Survey six-inch map, which labels it a "Cromlech", an older and now largely deprecated term once used loosely to describe megalithic structures of various kinds. That the word appears on just one edition of one map suggests the site was already slipping from local memory by the early twentieth century, known well enough to be marked, but not well enough to be described with any precision.
