Where a V-shaped drain cuts north to south through the field, burnt material is exposed on both opposing faces, giving a glimpse into what lies beneath the uneven, waterlogged surface. On the western side of the drain, a spread of this burnt material, mixed with upcast spoil, runs roughly twenty metres north to south and eighteen metres east to west. A narrower spread sits on the eastern side. Together, they mark the disturbed remains of what archaeologists believe to be a fulacht fia.

A fulacht fia is a type of prehistoric cooking site, typically consisting of a mound of fire-cracked stone accumulated beside a trough or pit used for boiling water. They are among the most common archaeological monuments in Ireland, found especially in low-lying and wet ground, and most date to the Bronze Age. This particular example appears to correspond with a site recorded in the 1940s as covering some 400 square yards, roughly 334 square metres, on land then belonging to a man named Daniel O'Keeffe. The record, preserved in the Schools Manuscript collection for County Kerry, notes that material from the mound had been drawn off and used as road fill, a fate that was not unusual for these monuments, whose loose burnt stone made them a convenient and free source of hardcore. That removal likely accounts for the reduced and scattered state of the remains visible today.
