The field where it lies has been absorbed into reclaimed pasture, its surface smoothed over by centuries of agricultural use. The only time the place ever revealed itself was under the blade of a plough, when a spread of burnt and scorched material came briefly to light before being swallowed back into the earth.

What the plough disturbed was almost certainly a fulacht fia, a type of prehistoric cooking or processing site found in considerable numbers across Ireland. The typical form involves a trough, usually timber-lined or stone-lined, into which water was poured; stones were heated in a nearby fire and dropped into the trough to bring the water to a boil, and the cracked, fire-shattered stones were then piled to one side, forming the characteristic horseshoe-shaped mound that survives at many such sites. At Lismeelcunnin, that mound is gone, but the burnt stone scatter is a recognisable signature of the type. A researcher named Bowman noted in 1934, in a publication that recorded the local archaeology of the area, that there were two fulachta fiadh on land belonging to a M. O'Sullivan in this townland, and this site is believed to be one of them. The pairing is itself a small detail worth noting; such sites often cluster, suggesting repeated use of favourable ground, perhaps near a reliable water source, over long periods.
