It is classified as a burnt spread, a term that in Irish archaeology typically refers to the scorched and heat-shattered stone debris associated with a fulacht fiadh, the enigmatic cooking or processing sites found across the Irish landscape. These spreads form when stones are repeatedly heated and plunged into water-filled troughs, eventually cracking and becoming useless, and are then discarded in a mound or smear across the ground. The result, over hundreds or thousands of years, is a characteristic dark, charcoal-rich deposit that shows up clearly from the air even when nothing is visible at ground level.

This particular spread came to light during an archaeological assessment carried out in connection with a Forest Road Licence application in the area. Aerial imagery from 2004 revealed the site as a distinct dark soil mark, measuring approximately 40 metres on a north-northwest to south-southeast axis and around 25 metres across. The location is telling: historic Ordnance Survey maps consistently show this part of the townland as a mixture of dry and marshy ground, and the eastern edge of the field is defined by a watercourse, a tributary of the Brogeen River, that also marks an old townland boundary. Proximity to a reliable water source is almost a diagnostic feature of burnt spreads, since the entire process depended on a ready supply. The combination of marsh, stream, and dark subsurface material fits a pattern repeated at sites across Munster and beyond, where prehistoric communities returned again and again to the same wet, marginal ground for purposes that archaeologists still debate, cooking being the most accepted explanation, though hide preparation, bathing, and textile working have all been proposed.
