The mound itself is oval, roughly 23 metres long and just over 20 metres wide, and it has a definite central depression, the kind of hollow that often signals something buried, collapsed, or long since removed from beneath the surface. Whatever its origins, the land around it has been worked and subdivided across generations, and the mound has been quietly incorporated into that working landscape rather than fenced off or remarked upon.

The site lies at Cill Mhuirbhigh, approximately 460 metres south-southwest of Dún Beag, a stone fort whose name translates roughly as the small fort. The area around Cill Mhuirbhigh, on Inis Mór, is dense with early medieval and prehistoric remains, and a stony mound with a central depression in this context could indicate any number of things: a collapsed cairn, which is a burial monument typically formed of heaped stones; the remains of a structures whose internal features have subsided over centuries; or something more difficult to classify without excavation. Paul Gosling documented it in the Archaeological Inventory of County Galway Vol. I, published by the Stationery Office in 1993, recording its dimensions and the curious detail of those converging field walls, but offering no firm interpretation of what lies beneath the grass and stone.
