A fulacht fia, the term used for a type of ancient outdoor cooking place typically consisting of a horseshoe-shaped mound of burnt and cracked stone beside a trough, was noted here in December 1982 as a small, irregular mound sitting within a turlough lake. Turloughs are seasonal limestone lakes, characteristic of the Connacht landscape, that flood and drain depending on the water table; they are not lakes in any permanent sense, but temporary occupants of low-lying ground. The presence of black earth and burnt cracked limestone at the site were the telling signs, the scorched residue left behind when heated stones were repeatedly plunged into water-filled troughs to bring them to the boil.

When archaeologists returned in June 1992, the turlough was still at a risen level and the mound had disappeared entirely from view, submerged or obscured beneath the water. A second fulacht fia had been recorded on the western edge of the same lake during the earlier visit, suggesting the area saw repeated use over time, though quite how these sites related to one another is unclear. The finds from 1982 were never more than tentative, the site described as a "possible" fulacht fia rather than a confirmed one, which itself speaks to how difficult these features are to read when the land keeps shifting around them.

The site sits in ordinary pastureland, and given the behaviour of the turlough, what is visible in any given season depends entirely on rainfall and the water table. There is no guarantee that the mound, if it survives at all beneath the surface, will ever be clearly visible again from the field edge.
