The mound is horseshoe-shaped, measuring roughly 7.3 metres across its northeast to southwest axis, open to the northwest and nearly flush with the ground at its southeastern end. Leaning stone slabs push up through the centre of it, indicating the presence of a trough approximately 2.3 metres by 1.44 metres, and there is scattered evidence of heat-shattered stone nearby.

A fulacht fia is a type of Bronze Age cooking site found in large numbers across Ireland and Britain. The basic method involved heating stones in a fire until they were intensely hot, then dropping them into a water-filled trough to bring the water to a boil. The cracked and broken stones, discarded after use, gradually built up into the characteristic horseshoe-shaped mound that survives at sites like this one. The proximity of a water reservoir roughly 15 metres to the southwest is consistent with the known pattern; these sites are almost always found close to a water source, whether a stream, a spring, or a natural hollow that retained water. A ringfort, the circular enclosed farmstead that was the standard rural settlement type of early medieval Ireland, sits about 115 metres to the southwest, suggesting that this area was occupied and used across a considerable span of time, though the fulacht fia and the ringfort need not be contemporary with one another.
