Beneath that canopy, where moss grows thin and patchy, bare patches of soil reveal something more telling: a dense scatter of limestone fragments in dark grey-black earth, the characteristic signature of a fulacht fia. These Bronze Age cooking sites, found in their thousands across Ireland, typically worked by heating stones in a fire, then dropping them into a water-filled trough until the water boiled. The discarded, heat-shattered stones are what survives, mounded up around the trough over repeated use, and it is exactly that accumulation of cracked limestone that surfaces here through the moss.

The mound itself is compact, measuring roughly nine metres east to west and seven metres north to south, and reaches about 0.8 metres in height at its western end. Its U-shaped central hollow, open to the south-west, measures approximately 2.5 metres by two metres at the mouth, and the eastern side of the structure presses against jutting bedrock, with a vertical rock face rising above it. The site was formally listed as a fulacht fia in the Record of Monuments and Places in 1996, but its existence in a broader landscape context was noted earlier: in 1994, Tom Coffey recorded a cluster of such sites in the area on annotated maps. That cluster is more than a footnote. A second fulacht fia lies roughly 50 metres to the north-east on the same terrace, and two further examples sit about 200 metres to the south-west on a higher terrace above. Whatever drew people to this particular stretch of the Burren, they returned to it, or others followed, leaving behind four separate monuments within a short distance of one another on the same limestone plateau.
