The qualification "said to be" is doing some work here, because when archaeologists came to look for it, they could not find it. The site exists on record primarily as a matter of local knowledge, a piece of information passed on by someone who knew the land, but which the ground itself declined to confirm on the day of inspection.

Burnt spreads of this kind are a reasonably familiar presence in the Irish archaeological landscape, particularly in low-lying or waterlogged ground. They are often associated with fulachtaí fia, the enigmatic burnt mound sites found across Ireland and dated broadly to the Bronze Age, though their precise function remains debated. The characteristic signature is scorched and shattered stone, sometimes mixed with charcoal and dark, greasy soil, the residue of repeated heating and quenching. Whether this Corbally spread belongs to that tradition is unknown. What is recorded is that another burnt spread lies approximately 120 metres to the north, which at least suggests the area has seen this kind of activity more than once.
