A fulacht fia, to use the Irish term, is a type of ancient burnt mound associated with Bronze Age cooking, typically formed by heating stones in a fire, dropping them into a water-filled trough to bring it to the boil, and then discarding the cracked, heat-shattered stones in a heap nearby. Over centuries, those heaps of fire-cracked stone and charcoal-rich earth accumulate into low, often horseshoe-shaped mounds, which tend to survive well in wet ground because the waterlogged conditions preserve organic material and discourage disturbance. This one, however, has left almost nothing behind.

By 1937, when the Ordnance Survey produced its six-inch map of the area, there was still enough of a rise in the ground to be recorded as a mound. At some point between then and the present, even that low profile vanished. The site now shows no visible surface trace, which means the mound has either been levelled by agricultural activity, eroded away, or simply settled so far into the marshy ground that nothing distinguishes it from the surrounding landscape. What was once a feature legible enough to catch a surveyor's eye is now, to all appearances, gone.
