Roughly two metres of this burnt spread continues outward to the south-south-east, suggesting the deposit is not confined to the drainage channel but extends into the surrounding ground. It is the kind of thing that goes unnoticed for generations until a spade or a digger exposes a cross-section and the dark, scorched layer suddenly appears.

Deposits of this kind are often associated with fulachta fiadh, a type of prehistoric cooking or industrial site found in considerable numbers across Ireland, typically in low-lying or marshy ground near a water source. The method generally involved heating stones in a fire, then dropping them into a water-filled trough to bring the water to a boil. The cracked and shattered stones, blackened by repeated heating, accumulated into a mound or spread around the trough over time. The presence of a spring well nearby, noted in local knowledge, fits that pattern well. Burnt spreads of this sort date most commonly to the Bronze Age, though some examples span a wider range, and without excavation it is impossible to say more precisely what activity took place here or when.

The site sits in ordinary farmland, with nothing on the surface to mark it out. The burnt layer is visible only in the section exposed by the drain, which runs roughly north-east to south-west across the field.
