What came to light near Kilcor was a spread of burnt material, the characteristic signature of a fulacht fia, one of the most common yet still not fully understood monument types in the Irish landscape.

Fulachtaí fia, found in their thousands across Ireland, are the remains of prehistoric cooking or processing sites. The typical form is a horseshoe-shaped mound of fire-cracked stones and charcoal-rich soil, built up over repeated use. The working method involved heating stones in a fire and dropping them into a water-filled trough to bring the water to a boil, a technique that leaves behind exactly the kind of scorched, fragmented debris that appeared at Kilcor. The site was identified in 1987, recorded by Cleary and colleagues, and noted as unexcavated. That status has not changed. Whatever the ground at Kilcor still holds, whether a timber trough, animal bone, or charred wood suitable for radiocarbon dating, it remains undisturbed beneath the surface, the pipeline having revealed just enough to confirm the presence of something worth recording.
