The wall is curvilinear, meaning it follows a gently curved rather than straight line, a form more commonly associated with early medieval or prehistoric enclosures than with the rectilinear field systems introduced during later centuries of agricultural improvement. At roughly sixty centimetres thick and forty centimetres high where it is visible, it is modest in scale, but it extends for approximately seventy metres up from the northern bank of the river before the bog finally claims it.

What makes it quietly compelling is the detail of the upright stones set at right angles to the main wall line. This kind of arrangement suggests the boundary was more than a simple property marker; the projecting stones may have served as reinforcement, as anchoring points, or as part of a system for controlling the movement of animals across rough hill pasture. A hut site recorded approximately fifteen metres to the north implies that someone not only farmed this ground but lived on it, and the two features together begin to suggest a small, self-contained world tucked into a valley that is now largely given over to bog. The gradual encroachment of that bog over the wall is itself a piece of history, a record of how land that was once dry and workable became waterlogged over time, preserving the stonework even as it buried it.
