In July 1989, aerial photography revealed a pattern of fragmented rectilinear cropmarks spread across roughly 2.3 hectares, some running perpendicular to one another in a way that suggests not one but at least two field systems laid down at different times, their boundaries overlapping and cutting across each other in the soil.

Cropmarks form when buried features such as ditches, walls, or banks affect how crops grow above them, producing variations in colour or height that become legible only from altitude and usually only under particular light and moisture conditions. That the Scart marks appear fragmented rather than continuous points to centuries of disturbance, either through later ploughing, drainage, or the imposition of newer land divisions onto older ones. The site sits within a cluster of related features: a polygonal enclosure lies in the next field to the north, and a rectangular enclosure in the field to the east, suggesting this patch of North Cork was organised and reorganised repeatedly across a long period of human use. Without excavation, precise dating remains impossible, but the overlapping geometry alone implies that whoever farmed or bounded this land did so in more than one distinct phase.
