The field is known locally as the "big meadow", and it runs along the north side of a stream, which is precisely where you would expect to find a fulacht fia. These are ancient outdoor cooking sites, typically Bronze Age in date, where water was heated by dropping fire-cracked stones into a trough; the shattered, blackened stone accumulated in a horseshoe-shaped mound around the pit, and it is this burnt material that tends to survive.

What survives at Curracahill is slight but telling. Burnt material spreads for roughly seven metres along a field fence running parallel to the stream, and its depth varies considerably, from around fifteen centimetres on the north side of the fence to as much as 1.2 metres on the south side. That variation in depth suggests the mound was once more substantial, and that the fence line cuts across it at an angle. By the time Broker recorded the site in 1937, the structure had already been cleared, the note reading simply that it was "removed long since, traces there still." The site was, in other words, already a ghost of itself nearly ninety years ago, reduced to scorched earth and the faint profile of what had once been a working mound.
