When it came to notice in 1996, the spread measured roughly five metres across, exposed where the covering layer of peaty soil had been disturbed. Even then, its full extent could not be determined, its edges dissolving into the surrounding ground.

The site is a fulacht fia, a category of monument found in great numbers across Ireland, particularly in low-lying, wet ground near water. The term, loosely translated as "cooking place of the deer," refers to the characteristic mounds of fire-cracked stone that accumulate where water was repeatedly heated by dropping hot stones into a trough. The method was efficient, and the sites cluster wherever people needed to cook, process hides, or perhaps bathe, over extended periods of prehistory. What makes this particular example notable is not its individual size but its context: it sits within a linear cluster of fulachtaí fia running along the course of the Fiddaunglass stream, with at least one further example recorded just twenty-five metres to the south-south-east. The grouping suggests sustained, repeated use of this particular stretch of water over time, the stream itself as much a part of the archaeology as the scorched stones beside it.
