What was once recorded as a midden, a word for the accumulated refuse of past human settlement, typically comprising shells, bones, ash, and other domestic waste, has left no visible trace on the surface. The shells noted by the writer Tim Robinson in 1980 are gone, absorbed back into the landscape or disturbed beyond recognition, and what remains instead is a substantial drystone wall that was never quite the point.

Locally the site is known as Creig an Bheallach, and the wall itself is considerable: more than twenty-one metres long, roughly five metres wide, and still standing to about a metre in height, running on a northwest to southeast axis across the gentle north-facing slope. Drystone construction, which uses no mortar and relies entirely on the careful placement of stone against stone, was the dominant building method across the Aran Islands for centuries, and the technique is still visible throughout the island's landscape today. This particular wall, however, has been robbed at both ends, meaning that later generations removed stones from it to build the field boundaries that now pattern the surrounding land, a common fate for ancient structures in areas where useful stone was scarce. The midden that gave the site its classified name had already vanished by the time Robinson documented it, and by the 1990s even that documentary trace had faded into absence.
