It is not especially dramatic to look at; heather and gorse have colonised its surface, and at a maximum height of around 1.2 metres it could easily be passed off as a natural feature of the boggy ground. What gives it away is what lies inside: heat-shattered stones packed into dark grey soil, the signature of a burnt mound, a type of prehistoric cooking site found across Ireland and Britain in their hundreds.

Burnt mounds, known in Irish archaeology as fulachtaí fiadh, are among the most widespread monuments of the Bronze Age, though their precise function has been debated for decades. The most widely accepted explanation is that they served as outdoor cooking places, where stones were heated in a fire and then dropped into a water-filled trough to bring it to the boil. The shattered, fire-cracked stones were discarded to the side after each use, gradually building up the distinctive horseshoe or semi-circular mounds that survive today. This example measures roughly 11 metres east to west and 7 metres north to south, accumulated against the rising slope over repeated episodes of use. The damp, rush-grown pasture surrounding it, with drier grazing ground upslope, is exactly the kind of waterlogged, low-lying terrain where these sites consistently appear. What makes this particular spot a little more striking is that a second burnt mound lies just 10 metres to the west, suggesting the area saw sustained or repeated activity, with communities returning to this spot beside the lough across a considerable span of time.
