What makes it quietly remarkable is the sheer density of what survives within it: cairns, cashels (the circular stone enclosures that served as defended farmsteads in early medieval Ireland), hut sites, and fulachtaí fia, the last of which are the scorched, mounded remains of prehistoric cooking sites, typically identified by their characteristic horseshoe-shaped spreads of fire-cracked stone.

The system is not uniform in shape. Its northern half, sitting just 500 metres west of Corkscrew Hill on a shelf along the eastern slopes of Faunarooska, is relatively narrow, spanning only around 360 metres from east to west, as though the terrain itself compressed the settlement into a defined corridor. Further south, as the ground drops to lower elevations, the system opens out to around a kilometre across, suggesting that pressure on land, or perhaps the logic of different farming periods, shaped how people extended and organised what they held. The full extent became legible only through aerial survey, the kind of overhead perspective that collapses centuries of vegetation and soil accumulation into a single coherent pattern.
