The wall is roughly ninety metres long, about seventy centimetres thick and forty centimetres high where it remains visible, and it curves downslope in a way that distinguishes it from the straight-edged boundaries of more recent agricultural work. Fallen rubble lies embedded in the bog alongside it, suggesting a structure that has been sinking and settling for centuries rather than decades.

What makes this boundary quietly arresting is less its size than its situation. Bog formation is a gradual process, and when a wall becomes subsumed into peat it signals a landscape that has changed substantially since the wall was first laid. At some earlier point, this hillside above the Flesk was being managed, divided, perhaps farmed or grazed in a more organised way than the rough hill pasture that surrounds the remains today. The curvilinear form of the wall is often associated with early medieval field systems in Ireland, where boundaries followed the natural contours of the land rather than being imposed in straight lines. A related enclosure sits approximately seventy metres to the south-west, suggesting that this was not an isolated feature but part of a broader pattern of activity on the slope.
