A detailed gradiometry survey was conducted over approximately 52 hectares of arable farmland. Cotton Henge, visible as crop-marks in aerial photography, has been identified, along with a small sub-circular feature which may be associated with a prehistoric barrow cemetery. A number of linear anomalies are likely to be related to prehistoric settlement activity, while further linear anomalies are of possible archaeological or agricultural origin. A number of former field boundaries and ridge and furrow suggest a more recent agricultural history. The remaining features are natural or modern in origin and include underground services, magnetic disturbance from nearby ferrous objects and fencing, scattered magnetic debris, a track-way and magnetic spikes that are likely to be modern rubbish.
