Investigation by D Britchfield of WA in advance of the construction of a Motorway Service Area comprising an evaluation to the north of the motorway, and a soil stripping, mapping and sampling exercise to its south in an area where evaluation by ASE in 2007 had revealed possible deposits of prehistoric origin. The soil stripping, mapping and sampling exercise revealed a post-medieval ditch, suggested to be a remnant of an 18th century field system, but no further evidence of the admittedly ambiguous features identified in 2007. Much of the evaluated area proved to be heavily truncated as a result of extensive remodelling associated with the construction of the M25, but a further section of the field system was identified outside of the truncated area.
