Measuring roughly thirteen metres along its longer axis and rising to just over a metre at its highest point, it has a central hollow nearly four metres wide that opens out to the west-southwest, a feature that distinguishes it from a simple field clearance heap and suggests it may once have served a more deliberate function.

The mound came to attention during fieldwork carried out as part of the AranLIFE Farming Project, a study running between 2014 and 2018 that examined the traditional agricultural landscape of the Aran Islands. Located at the south-western end of the island, at the base of a low terrace, it sits in an agricultural setting that has shaped and been shaped by generations of small-scale farming. A water trough has been constructed to its east at some point, suggesting the land around it has remained in active use. What makes the find quietly compelling is that a second, closely comparable mound lies in the adjacent field, roughly twenty metres to the south-west, hinting that whatever these features are, they were not accidental or isolated. Two similar structures in neighbouring fields, on a small island already dense with early medieval and prehistoric remains, raise more questions than current evidence can answer.
