On the 1932 edition of the Ordnance Survey six-inch map, a hachured symbol at Kinclare in County Galway suggested the kind of earthwork that might prompt closer attention, the sort of mark that can indicate a rath, a mound, or some other feature of pre-modern origin. When someone finally went to look in 1983, they found a shallow dip in a cleared field of flat grassland, the faint depression of a disused gravel pit, almost imperceptible to anyone who was not specifically searching for it.
