A substantial ditch, flanked by banks on either side, is visible running roughly parallel to the River Stour on 1940s aerial photographs. The ditch runs for 600m on a sinuous E-W course and is flanked by banks on both sides over most of its course. These features do not appear to be part of the field system shown in this area on historic Ordnance Survey mapping. It is likely that they are of medieval or earlier post-medieval date and may represent water management features related to the reclamation of land from the Wantsum Channel during these periods. The features appear to have been largely plough levelled by the 1960s as Ordnance Survey vertical aerial photographs of this date show them as cropmarks.
