It measures thirteen metres east to west and six and a half metres north to south, rising to about ninety centimetres in height, with its opening facing north. Dense ferns and gorse have grown thickly over it, which is precisely the kind of vegetation that tends to colonise these features and, in doing so, preserve them.

The mound is a fulacht fia, a type of prehistoric cooking site found in considerable numbers across Ireland, typically dating to the Bronze Age. The usual interpretation is that water was heated in a trough by dropping fire-cracked stones into it; those spent, blackened stones were then raked aside into a mound, which is what survives. The characteristic burnt and shattered material in such mounds is what makes them identifiable even when nothing else remains above ground. What makes this particular example quietly interesting is that another probable fulacht fia lies just three metres to the south, suggesting repeated or overlapping use of the same sheltered, well-watered slope over time. Proximity to a stream is almost always a feature of these sites, since a reliable water source was essential to the whole process.
