A shell midden, the accumulated debris of shellfish consumption over time, was recorded within the interior of this large stone enclosure, only to have vanished entirely by the time anyone went looking for it in 1997. The official record noted its existence; the site itself offered nothing.

A cashel is a roughly circular stone enclosure, typically of early medieval date in the Irish context, used to define and defend a farmstead or settlement. This one sits at the northern end of its valley, and within its walls there were once at least two house sites as well as the midden deposit. Shell middens of this kind represent the mundane arithmetic of daily life, layers of limpet, periwinkle, and oyster shell building up over seasons or generations wherever people were eating close to the coast and discarding their waste in the same spot. That the Burren's limestone interior supported communities with access to shoreline foods is itself a small, useful detail. The midden was documented through personal communication and entered into the Record of Monuments and Places in 1996, but a year later the physical evidence had either been disturbed, removed, or simply reabsorbed into the ground surface in a way that left no visible sign.
