They are not immediately legible as a field system. They protrude only intermittently, their tops showing above the peat in a rough rectangle about a hundred metres from north to south and sixty metres from east to west, and what emerges is a network of low boundaries rather than any single enclosure. The effect is of a landscape that has been swallowed almost entirely, and only partially given back.

The walls are built from upright stones set roughly at right angles to the direction of the wall itself, a construction method that reflects a practical approach to working with the material at hand on exposed upland ground. Where visible, the stonework reaches no more than about half a metre in height and is similarly narrow in width, suggesting these were working agricultural boundaries rather than defensive structures. Nestled within the network, and recorded separately, is a hut site, the remnant of what was once a dwelling or seasonal shelter. Taken together, the field system and the hut point to a period when this boggy hillside was actively farmed, before the encroaching peat gradually buried the evidence of that occupation. Bog has a tendency to preserve what lies beneath it, and in this case it has preserved the shape, if not the full height, of a small agricultural world that would otherwise have vanished entirely.
