The feature appears as a hachured depression on the 1948 revision of the Ordnance Survey six-inch map, while the more detailed twenty-five-inch plan names it plainly as a sand pit, already disused by the time the surveyors passed through. Hachuring, a system of short radiating lines used by cartographers to indicate slopes or hollows, was the standard way such workings were marked before contour lines became universal, and it gives the feature a slightly antique look even on a mid-twentieth-century sheet.
