Description
A geophysical survey (fluxgate gradiometer mounted on a hand cart) was undertaken by Magnitude Surveys across a 10.2 ha. area of land on the west side of Dawes Lane in October 2019.<1>
No anomalies indicative of archaeological activity have been identified in the survey area; anomalies of natural origin dominate instead the results. Natural variations have been detected across the survey area with linear anomalies forming an irregular lattice pattern). The anomalies follow several cropmarks previously identified from aerial photographs and most likely reflect fracturing of the underlying Pliocene Clays silts and sands, and subsequent infilling by overlying deposits.
Several linear anomalies indicative of drainage features have been noted running north-south
across the survey area. Evidence of historic agricultural land usage consists in fragmentary, discrete anomalies positioned along field boundaries identified on historic OS maps.
