The wall is modest in scale, roughly half a metre thick and barely above knee height, yet it extends for some 34 metres from the arc of a nearby enclosure down to a stream. That it is visible at all is largely because peat growth, though it buries much, does not always bury everything evenly.

This is what archaeologists call a relict field boundary, meaning a division of land that ceased to function at some point in the past and has since been absorbed, at least partly, into the surrounding bog. The construction technique is worth noting: large slabs are set end-on, that is, with their narrow edge facing outward along the line of the wall, while smaller slabs are placed at right angles to it, a method that gives the structure a degree of interlocking stability. The wall abuts a pre-existing enclosure to its south-east, suggesting it was part of a wider arrangement of managed land. A second relict boundary was recorded on the north side of the same enclosure during survey work in the 1990s, but by the time researchers returned to document it more carefully, it had disappeared below ground level entirely, consumed by the bog or simply too degraded to distinguish from the surrounding terrain. The visible wall to the south-east is, in that sense, the survivor of what was once a more elaborate pattern of fields and boundaries on this hillside.
