It runs for roughly 24 metres in a northwest to southeast direction before disappearing back into the bog, and it stands only about 30 centimetres above the surface, barely knee-height. That it is visible at all is something of an accident of topography: the wall sits at a slight break in the slope, just enough of a shift in the hillside to have preserved it above the creeping accumulation of peat that has swallowed the rest.

This is a relict field boundary, meaning it belongs to a period of land use that has long since ended, the surrounding landscape having reverted to rough hill grazing. The wall is approximately 60 centimetres thick, built from one to two stones in width, with some stones set at right angles to the main line of the wall, a construction technique that lends a degree of lateral stability. Near its northwestern end, the boundary makes a short turn to the northeast, extending about 2 metres in that direction before stopping. Whether that turn once connected to another wall, or enclosed a corner, is no longer clear. What is clear is that this boundary did not stand alone: it begins about 17 metres to the southeast of a recorded hut site, suggesting that at some point this hillside was not simply grazed but lived on, the wall marking out ground that someone considered worth dividing and defining. The bog has since made its own claim on the land, and the hut and the greater part of whatever field system once existed here have been absorbed into it.
