These are pre-bog walls, meaning they predate the formation of the blanket bog that eventually buried and, in doing so, preserved them. Where the bog has eroded or been cut away, the outlines of an entire farmed landscape come into view.

The remains are scattered across an area measuring approximately 1.2 kilometres north-east to south-west and 600 metres north-west to south-east, which gives some sense of the scale of the original settlement. The walls form a broken network of both curvilinear and rectilinear fields, with the longer stretches, some reaching up to 100 metres, oriented east to west. They are modest things physically, averaging about a metre wide and half a metre high, but collectively they describe a community that once organised land, livestock, and labour across this now largely empty hillside. The field system does not stand alone. Within the same area are two small enclosures, a hut, and two fulachta fiadh. A fulacht fiadh is a type of prehistoric cooking site, typically identified by a horseshoe-shaped mound of burnt and fire-cracked stone beside a trough, and they are among the most common ancient monuments in Ireland, though finding them alongside a functioning field system adds context to both. The smaller of the two enclosures, near the northern limits of the complex close to the Coomavoon and Keel townland boundary, is subcircular in plan with an internal diameter of 5.6 metres, a roughly built bank of boulders and earth, and a poorly defined entrance just under two metres wide on the north side. Its interior is now filled with loose stone.
