It is a fulacht fia, a type of prehistoric cooking site found in great numbers across Ireland, typically identified by a horseshoe-shaped mound of heat-shattered stone left over from repeated use. The basic method involved heating stones in a fire, then dropping them into a water-filled trough to bring it to a boil. Over time, the cracked and spent stones were raked aside, accumulating into the distinctive mound that survives, in reduced form, here.

The site may be one of a pair. In 1937, a researcher named Broker noted two fulachta fiadh on the farm of a Mrs Daniel Dennehy, recording them in what appears to have been a local or regional survey. This site at Cloghboola More is a candidate for one of those two, but the other, catalogued separately, has never been definitively located. The mound's current flattened state reflects what often happens to these sites once farmland is improved and ploughed; what was once a visible feature becomes a faint shadow beneath pasture grass, identifiable mainly by the scorched, fragmented stone beneath the surface.
