It covers a modest area of roughly six metres north to south and six metres east to west, and it came to light not through formal excavation but through farm road works, which disturbed and spread the material intermittently across the ground surface.

What lies beneath such spreads is often the residue of a fulacht fiadh, the Irish term for a prehistoric burnt mound, one of the most common yet least understood monument types in the Irish landscape. These sites typically preserve large quantities of fire-cracked stone and charcoal, the byproduct of repeatedly heating stones and plunging them into water-filled troughs, a process associated with cooking, bathing, or industrial activity during the Bronze Age. The disturbance here means the original deposit has lost much of its stratigraphic integrity, but the burnt material itself survives as evidence of past activity on this hillside. A second burnt spread sits approximately forty metres to the west, which suggests this part of Islandearagh was used repeatedly or over a sustained period, perhaps drawn by a water source or the particular character of the slope. The site looks out south-westward toward the Paps of Dana, the twin-peaked hills in the Derrynasaggart Mountains that have carried mythological and ritual associations since early medieval times, named for the goddess Danu of the Tuatha Dé Danann.
