Sitting in rough hill pasture and embedded within an older field system, it survives as a horseshoe-shaped mound of burnt material, grass-covered now, measuring roughly 8.5 metres northeast to southwest and 8 metres northwest to southeast, rising to about 1.3 metres at its highest point. The opening of the horseshoe faces northwest and spans around 4 metres across, which is where erosion has begun to expose some of the dark, scorched material beneath the turf.

A fulacht fia, broadly speaking, is a Bronze Age cooking site, or at least that is the most widely accepted interpretation. The typical arrangement involved a trough dug into the ground, filled with water, and heated by dropping fire-cracked stones into it. Those stones, once spent and discarded, accumulated over time into the characteristic horseshoe mound that surrounds the trough on three sides. The burnt and shattered stone that makes up these mounds is almost always what survives, since the timber troughs and any organic material associated with them have long since decayed. What makes the Gearhanagoul example quietly interesting is its setting within a relict field system, with a wall of that system extending northward from the northern arm of the mound, suggesting the site was not simply abandoned in open wilderness but became incorporated, at some point, into a managed agricultural landscape.
