Within the grounds of Eyrecourt Demesne in County Galway, there once existed a sand pit substantial enough to be marked and named on Ordnance Survey mapping, yet by the time anyone went looking for it on the ground, it had gone entirely. No hollow, no exposed face, no change in the vegetation to suggest the earth had ever been disturbed there.

The feature appears on the 1944 to 1945 revision of the Ordnance Survey six-inch map, rendered with hachures, the small radiating lines cartographers use to indicate a pit or depression in the terrain. The larger scale twenty-five inch plan names it plainly as a sand pit, and marks it as already disused. When the site was inspected in 1984, the surrounding land had been reclaimed as undulating pastureland, and no visible surface trace of the pit survived. The reclamation had been thorough enough to erase whatever physical impression the extraction had left behind.
