It is only about six metres across at its widest and barely a metre across the bank itself, with the interior rising no more than twenty centimetres above the surrounding ground. What it describes, once you know what to look for, is the footprint of a booley hut, a temporary shelter used during the seasonal practice of booleying, the Irish form of transhumance in which families or herders drove their cattle to upland summer pastures and lived beside them for the grazing season.

The structure is semi-circular, or roughly C-shaped, running from east through south to west, leaving the northern side entirely open. This orientation is not accidental. Positioning the closed arc to the south and east would have offered some protection from prevailing winds while keeping the entrance sheltered. Booley huts were rarely built to last; they were functional, seasonal constructions, typically low-walled and roofed with whatever materials were to hand, which is precisely why so few survive even as earthworks. The bank here, composed of earth and stone and long since colonised by moss, is all that remains of what would once have been the base of such a structure. The interior is now grassed over, leaving little sign of the domestic activity that once filled it.
