What makes it faintly curious is the gap between what it appeared to be on paper and what it turned out to be in person. On the 1932 edition of the Ordnance Survey six-inch map, the spot was marked with hachures, the short radiating lines cartographers use to indicate a depression or earthwork, the kind of notation that can send an archaeologist's pulse quickening. A site inspection in 1983, however, resolved the mystery without much drama: the feature is most likely a disused sand or gravel pit, probably dug sometime after 1700, and long since abandoned to the grass.
