By the time cartographers surveyed the area between 1912 and 1916, the workings had already been classified as disused, recorded on the OS 1:2500 plan under the matter-of-fact label "Gravel Pits (Disused)". The 1931 edition of the six-inch map rendered the site with hachures, the cartographic convention of short radiating lines used to indicate a depression or earthwork, suggesting the pits still left a visible mark on the landscape at that point. When the site was physically inspected in 1984, even that had softened into little more than a hollow in the field.
