The area surveyed was located in an area where ditches seen in trial trenches could be confidently predicted to continue. Readings were taken at 0.5m intervals and transects taken 1m apart. None of the predicted lines of the ditches could be identified in the plots, though the area of intense activity SW of trench 06 did produce slightly higher magnetic readings. The opportunity was taken to test whether the 'burnt mound' deposits could be located. However, even when the 'burnt mound' type deposits were exposed, or covered by a maximum of 0.1m of colluvium, they only registered 1 - 2 nT above the background readings, insufficient to use this technique to locate such deposits.
