At Garraunnameetagh in County Galway, a hachured marking on the 1945 revision of the Ordnance Survey six-inch map, the kind of hatched symbol cartographers used to indicate a depression or earthwork in the landscape, drew enough attention to warrant a physical inspection. When someone finally went to look in 1984, they found a disused quarry, post-1700 in date and therefore too recent to fall under the scope of archaeological investigation. That was more or less the end of the official story.
