The mound measures roughly 3.5 metres across and rises only half a metre from the surrounding ground, yet that modest heap of burnt stone is the calling card of a fulacht fia, a type of prehistoric cooking site found in enormous numbers across the Irish landscape. The working theory is that stones were heated in a fire, then dropped into a water-filled trough to bring it rapidly to the boil, with the cracked and shattered stones discarded into a horseshoe-shaped mound around the trough after use. The wet, low-lying ground here, immediately beside a reliable watercourse, is exactly the kind of setting these sites favour.

What makes this particular example worth noting is that it does not stand alone. At least three other fulachta fia have been recorded in close proximity along the same stream, forming a small cluster in the narrow east-west valley. Whether they represent repeated use of a favoured spot over generations, or something more organised, is difficult to say without excavation, but their grouping is suggestive. The boggy ground immediately around the monument gives way to a steep slope just a few metres to the south, which would have offered dry footing close to the water, a combination that clearly appealed to whoever returned to this valley again and again.
