While the surrounding wetland produces reeds, this slightly raised hump, roughly eight metres by four and about a metre high, is covered in ferns. Beneath them lie burnt stones and charcoal, the characteristic remains of a fulacht fia.

A fulacht fia is a type of prehistoric cooking site found across Ireland in considerable numbers, typically sited near a water source. The general principle was straightforward: stones were heated in a fire and then dropped into a water-filled trough to bring it to a boil, used for cooking meat or possibly for other purposes including textile processing or bathing. The spent, fire-cracked stones were discarded to one side, accumulating over repeated use into the horseshoe-shaped or irregular mounds that survive today. This example sits to the north-west of a natural spring, which would have supplied the necessary water, with a modern field fence and road forming the north-western boundary of the site. The mound measures approximately eight metres on its north-east to south-west axis and four metres across, rising to about a metre in height, modest dimensions but consistent with many examples of the type found throughout the Irish landscape.
