At least four spreads of dark soil became visible when the field was turned over, observed from a distance and reported locally by Jane O'Shaughnessy. On subsequent visits, with the land returned to pasture, nothing could be positively confirmed.

What those dark patches might represent are fulachta fiadh, a type of prehistoric cooking site found in enormous numbers across Ireland, particularly from the Bronze Age. The typical form involves a trough, often timber-lined or stone-lined, filled with water, which was then heated by dropping fire-cracked stones into it. Over time, the shattered, burnt stone and charcoal-rich soil accumulate into a distinctive horseshoe-shaped mound. The characteristic dark, scorched earth is precisely what tends to catch the eye when a field is ploughed, which is why agriculture so often brings these sites to attention before grassing-over conceals them again. In this case, the evidence remained stubbornly ambiguous: the dark spreads were consistent with fulachta fiadh, but without closer examination, they could not be formally identified as such.
