The mound is roughly ten metres across and reaches about one and a half metres at its highest point, tapering away on either side into an inverted U shape. That particular profile is one of the things that caught the attention of observer John Loesberg, who identified it as a possible fulacht fia, a type of prehistoric cooking site found in considerable numbers across Ireland, typically dating from the Bronze Age. The classic model involves heating stones in a fire, dropping them into a water-filled trough to bring it to boiling point, and using the resulting heat to cook meat. Over time, the cracked and discarded stones build up into the characteristic horseshoe or kidney-shaped mound that survives long after everything else has disappeared.

What makes this particular example quietly puzzling is the question of water. Fulachtaí fia are almost always found near a reliable water source, usually a stream or spring, since the whole process depends on a ready supply. Here, no obvious watercourse runs close by. However, Loesberg noted that the soil to the east is saturated, and older, now-dry watercourses are visible in places, suggesting that the local hydrology has shifted over the centuries or millennia since the site was in use. The mound is also surrounded by dry stone walling, some of which appears to be ancient, and further intermittent stone walls extend across the broader area, hinting at a landscape that was organised and worked over a long period. Whether the fulacht fia classification will hold under closer examination remains an open question; the site has so far been recorded as a possibility rather than a confirmed example.
