What makes it immediately peculiar is the hollow at its centre, an irregular depression that suggests something was once built, buried, or collapsed here, and a pair of stone walls that slice through its edges at the north-west and south-east, apparently indifferent to whatever the mound originally was. The structure measures roughly 21 metres along its longer axis and rises only about a metre and a half, modest dimensions that might cause a casual walker to dismiss it as a natural undulation in the ground.

The mound forms part of a broader archaeological grouping recorded as Baile na mBocht, a place name that translates from Irish as something close to "townland of the poor." The site was noted by Tim Robinson, the cartographer and writer who spent decades mapping the landscapes of Connemara and the Aran Islands in extraordinary detail, and his 1980 observation was later incorporated into the published archaeological inventory of West Galway compiled by Paul Gosling in 1993. The mound is composed mainly of stone beneath its grassed surface, which distinguishes it from earthen burial mounds and raises questions about whether it was ever a field clearance feature, a structural remnant, or something altogether older. The central depression is a detail worth dwelling on; similar features elsewhere in Ireland sometimes indicate the collapse of an internal chamber or the robbing out of stone over centuries.
