Earth Resistance Survey

In 2002 and 2007 earth resistance surveys were carried out. The results (seen below) can be sub-divide into three areas.

1 - The field to the south of the boundary on which enclosure lies (Grids 1-6). This shows little evidence of variation within the rsults except what appears to be a large pit in Grid 5 and partially in Grid 4

2 - The field to the north of the boundary on which the enclosure lies and which surrounds the enclosure (Grids 7-12). This shows what appears to be a series of linear anomalies which appear to form a rectangle. No definite interpretation can be made for this feature but it is thought to relate to a drilling operation carried out in the mid twentieth century (see below).   A vague sub-oval anomaly can just be seen 'inside' this  rectangle. This sub-oval anomaly related to a former pit excavated around a broken drilling rig pipe (see below). 

3 - The internal land within the enclosure. This shows a central almost circular grey area suggesting loser soil surrounded by darker grey and black areas suggesting more compacted soil. The boundaries of the enclosure show linear black boundaries on its northern and to a lesser extent on its eastern side suggesting very dense compacted soil. It is possible that the vague circle represents the remains of a very large pit excavated by Woodford in 1818 and the darker areas represent the un-returned spoil from his excavations.
