When inspected in 1998, fragments of shattered stone and charcoal-dark soil were still surfacing intermittently through the thin turf, the scattered remnants of what was probably a fulacht fia, a type of prehistoric cooking or processing site typically consisting of a horseshoe-shaped mound of fire-cracked stone built up beside a water source over repeated use. This one had been levelled, most likely during land reclamation, and so little of it survived that its full extent could not be measured.

Fulachtaí fia are among the most common archaeological monument types in Ireland, found in their thousands across the country, almost always close to water or marshy ground. The working interpretation is that stones were heated in a fire and then dropped into a water-filled trough to bring the water to a boil, though what exactly was being boiled, whether meat, hides, or something else entirely, has been debated for decades. The Tooraree site sits within a small cluster of such monuments. A second fulacht fia survives about a hundred metres to the south-east, while a third, noted in earlier records a short distance to the north-west, had left no visible trace at all by the time the area was examined.
