They are not dramatic, averaging only about half a metre in height, but their curved form and association with a shallow depression set them apart from natural landforms. These are the kinds of traces that reward careful attention rather than a passing glance.

The banks sit on the southern side of the reef, to the north-west of a separate enclosure that contains a cave entrance, suggesting this corner of Kerry preserves more than one layer of prehistoric activity in close proximity. According to research by Michael Connolly, presented in his 2008 doctoral thesis at University College Cork on the prehistoric settlement of the Lee Valley near Tralee, the banks and their associated depression may indicate the presence of a further, as yet uncharacterised, archaeological feature. An enclosure in this context refers broadly to a defined area bounded by banks, ditches, or walls, a form used across prehistoric Ireland for settlement, ritual, or agricultural purposes. What precisely this particular arrangement enclosed, or what activity the shallow depression records, remains an open question.
