Horseshoe-shaped in plan, it measures roughly fourteen metres along its longer axis and rises to about 1.6 metres at its steepest northern edge, where it drops away sharply before flattening more gently towards the south. A collapsed field wall cuts across it from east to west, the kind of detail that suggests generations of farmers working around something they could not easily remove or simply chose to leave alone. The mound opens to the west-northwest, giving it an orientation that carries a faint suggestion of deliberate design.

The monument came to light during the AranLIFE Farming Project, a survey of agricultural heritage across the Aran Islands carried out between 2014 and 2018. Its shape initially raised the possibility that it might be a fulacht fia, a type of prehistoric cooking site typically identified by a horseshoe-shaped burnt mound formed from the repeated heating and cracking of stones used to boil water in a trough. However, the current assessment leans toward a different interpretation: that this is more likely a settlement mound, possibly the remains of a round house, the circular dwelling form that was common across Ireland from the Bronze Age onward. A second mound of similar character lies approximately forty-five metres to the southwest, which raises the possibility that the two features are connected, perhaps the remnants of a small enclosed or clustered settlement whose precise date and function remain unresolved.
