These are relict field boundaries, meaning walls that predate the current pattern of land use and no longer function as working enclosures. They survive here as intermittent stretches across a roughly rectangular area of around 100 metres by 70 metres, the individual walls standing roughly 0.6 metres high and about 1.6 metres thick. The ground around them is thin and stony, which turns out to be a clue rather than incidental detail.

The exposure of so many wall sections appears to owe something to turf-cutters who worked this hillside in the past. Cutting and removing peat gradually strips away the covering that accumulates over centuries, and in doing so it can bring older landscape features back to the surface. The best preserved portion of the boundary system forms a roughly D-shaped enclosed area, about 70 metres across its longest axis, with a notably straight edge along its northwest side extending some 50 metres. That geometric regularity, faint as it is across rough grazing ground, is legible enough that it was recorded on the Ordnance Survey six-inch maps, those extraordinarily detailed mid-nineteenth-century surveys that captured field patterns, ruins, and townland features across the whole island. The valley to the west, opening towards Mullaghmesha, would have made this slope a logical place for enclosure at some point in the past, though exactly when these walls were in active use is not recorded.
