Buried beneath the bog for centuries, a relict stone field boundary now sits exposed on the mineral soil beneath, running roughly forty metres north to south, its stones set at right angles to the old boundary line and largely swallowed still by heather and gorse. It is not dramatic in appearance; at roughly seventy centimetres thick and thirty centimetres high, it reads less as a wall than as a long, interrupted suggestion of one.

What makes it quietly remarkable is what its survival implies. Bogs grow slowly and incrementally, layer by layer, and for a field boundary to be preserved beneath one, it must predate the bog's formation at that particular spot, meaning the land was once open, dry, and actively farmed before the waterlogged conditions took over. The boundary lies close to a togher, which is a wooden trackway typically constructed to allow passage across boggy or marshy ground, suggesting this whole area was once a working agricultural landscape before the bog advanced. The Adrigole River valley stretches away to the south, and the slopes here would have offered reasonable grazing ground before the conditions changed. Cutaway bog, where the upper layers of peat have been removed through turf-cutting, frequently exposes these kinds of pre-bog features, returning them briefly to the surface after an absence that can span thousands of years.
