The enclosure is circular, roughly 22.9 metres across, and defined by a bank that rises only 0.3 metres above the surrounding ground and stretches between one and one and a half metres wide. It is the kind of feature that would be easy to walk across without noticing, yet its geometry is deliberate, its purpose once meaningful enough to warrant the labour of construction.

What makes the spot more than just a single earthwork is the cluster of archaeology around it. A second enclosure of the same broad type lies about 50 metres to the east-northeast, and to the south and southeast there are clearance cairns, mounds of stone gathered and piled by people clearing the land for agriculture or grazing. Clearance cairns are among the more understated forms of field monument: no drama of construction, just the accumulated effort of hands moving rock out of the way, the cairns growing incrementally as the ground was made workable. Together, the enclosures and cairns suggest a landscape that was once actively farmed and organised, before the peat began its slow recovery over the ridge.
