Poking through the soft, waterlogged surface are the collapsed remains of stone field walls, their lines curving and branching across a roughly oval area of around 120 metres east to west and 80 metres north to south. What makes the sight quietly arresting is not any single dramatic feature but the sheer persistence of pattern: the walls are mostly fallen, reduced to low ridges of tumbled stone around half a metre high, yet enough of their layout survives to suggest the organised division of land that once took place here, at the foot of a south-facing rocky slope.

These are relict field boundaries, meaning they belong to an agricultural system that was abandoned and then gradually swallowed by encroaching bog. The bog preserved them rather than erasing them, which is why the stone courses still protrude above ground at all. At intervals along the walls, upright slabs have been set at right angles to the main wall line, a construction technique seen in various forms of Irish field walling and likely intended to reinforce or stabilise the boundary. The walls themselves are curvilinear in plan, which often indicates considerable age; early medieval and prehistoric field systems in Ireland commonly follow organic, curved alignments rather than the straight lines associated with later planned enclosures. Without excavation it is difficult to assign a precise date, but the combination of relict status, boggy burial, and curvilinear form points to a landscape that was active a very long time ago.
