Stone walls, now reduced to traces roughly half a metre high and just over half a metre thick, push up intermittently through the peat across an irregularly shaped area measuring around eighty metres east to west and sixty metres north to south. They are relict field boundaries, the surviving edges of enclosures that once divided this south-east-facing slope into workable ground.

What makes the site quietly strange is the detail that the walls have not simply sunk or collapsed in line. Several upright slabs are set at right angles to the main wall lines, a feature that suggests deliberate construction rather than casual field clearance. The boundaries are not continuous; they appear and disappear as the bog surface rises and falls across the rough terrace, with outcropping rocks punctuating the slope to the west. Relict field systems of this kind, sometimes called fossil landscapes, are common throughout the Irish uplands, where peat growth after the abandonment of marginal farmland has preserved, and simultaneously obscured, the evidence of earlier agricultural use. The bog both buries and protects, keeping stone courses intact even as it renders the original ground surface invisible.
