What it marks is a fulacht fia, one of the most common yet least understood prehistoric monument types in Ireland. These are the remains of ancient outdoor cooking sites, typically Bronze Age in date, where stones were heated in fire and then dropped into a water-filled trough to bring it to the boil. The process left behind characteristic spreads of shattered, burnt stone and charred soil, often arranged in a horseshoe or crescent shape around the trough pit.

This example was recorded by Alan Hawkes of University College Cork, who noted the crescent opening to the west, where a clear depression in the ground may indicate the original position of the trough. A slight mound was also visible, particularly to the south and east, which is consistent with the accumulated dumping of used, heat-shattered stone that typically builds up around these sites over repeated use. The overall spread measures 20.6 metres north to south and 15.5 metres east to west, making it a reasonably substantial example. The elevated position upslope from the glen would have kept the site above the worst of the surrounding wet ground, while still allowing access to water lower down, a practical arrangement seen at many fulacht fia across Munster.
