Turf-cutting, the centuries-old practice of harvesting compressed peat for fuel, has stripped back the bog sufficiently to expose a series of relict stone field boundaries sitting on the mineral soil beneath. The walls, roughly half a metre high and about the same in thickness, trace a rectangular area of approximately seventy metres east to west and sixty metres north to south. They are low, unspectacular things at a glance, but their presence beneath the peat is the point.

Relict field boundaries of this kind are found across Ireland wherever bog has accumulated over previously farmed or settled land, effectively sealing earlier landscapes in place. The Dursey example is unusual in that the same stones that once divided fields were later pressed into a second use: sections of the old boundaries were adapted into rectangular turf stands, the small enclosures used to stack and dry cut sods before they were brought home. That repurposing suggests people working the bog were aware they were cutting through something older, and simply folded it into their own practice. Those turf stands are now abandoned too, leaving a layered record of two distinct phases of activity, both of them finished.
