The pit was filled with heat-shattered stone, charcoal, and a small quantity of burnt bone, the characteristic debris of a fulacht fia.

A fulacht fia is essentially a prehistoric cooking or processing site, typically consisting of a trough or pit near a water source and an adjacent mound of fire-cracked stones. The method involved heating stones in a fire and dropping them into water-filled troughs to bring the water to a boil, a technique used for cooking, and possibly for other purposes such as textile processing or bathing. These sites are among the most common archaeological monuments in Ireland, mostly dating to the Bronze Age, yet individual examples are easily overlooked because they rarely survive as dramatic surface features. The Inchanappa site came to light not through a dedicated search but as part of broader archaeological test trenching carried out in 2005, catalogued under Excavation Licence 05E1193. The presence of burnt bone alongside the typical scorched stone and charcoal adds a small layer of complexity, suggesting that animal remains, whether food waste or something else, were part of whatever activity took place here.
