A geophysical survey, comprising detailed magnetometry, was carried out over a 850m long corridor ahead of the construction of a proposed new access track to Euridge Manor Farm, Colerne, Wiltshire. The survey was conducted using a hand-pushed, cart-based system of 5 magnetometers spaced 0.5m apart collecting data at 20Hz. The results indicate the presence of a number of positive linear and discrete anomalies which cannot be confidently interpreted as cut features. At the northern end of the corridor a number of positive linear, discrete and amorphous anomalies may relate to naturally formed features within the underlying geology, but an anthropogenic origin cannot be completely ruled out. The majority of the anomalies located within the site lie to the east of the proposed route of the new access track.
