The course of the wall was traced across NS 7215 7622 to NS 7250 7622. A geophysical survey in 1989 by Bradford University had suggested an alignment radically different from the traditional one plotted on OS maps; this was found to be erroneous, having been caused by a ridge of rock. The true line was established in Trenches 4 - 5 slightly N of that shown by the OS. Here the stone base was 4.2m wide with good kerbs. In Trenches 6 - 8, c.20m to the E, the stone base was missing, but the ditch was located. The berm in area B is c.9m wide. In Area C, where there is much disturbance by recent quarrying, the stone foundation was found to be increasingly robbed out, but the surviving section was 4.2m wide and the Ditch had a width of 9.2m, although nothing remained of an upcast mound.
