In the low-lying pastureland of Woodfield in County Galway, a gravel pit once occupied a subrectangular patch of ground, its outline recorded on Ordnance Survey maps with the hatched markings cartographers used to indicate disturbed or quarried terrain. By the time anyone went to look for it on the ground, it had already ceased to exist in any visible form.

The pit appears on the 1933 edition of the OS six-inch map as a hachured subrectangular area, and is labelled more plainly as a gravel pit on the larger-scale OS 25-inch plan. When the site was inspected in 1984, no surface traces had survived. The surrounding pasture had absorbed whatever hollow or spoil heap the workings once left behind, leaving the maps as the only record that extraction had taken place here at all.
