Detailed magnetometry using hand held magnetometers spaced 1m apart collecting data along 0.25m over 2.9ha. A detailed magnetometer survey was undertaken by Archaeological Surveys Ltd on land at Soho Farm, Leigh upon Mendip in Somerset. The results revealed a number of positive linear, rectilinear and discrete anomalies that may relate to natural features within the underlying Carboniferous limestone bedrock. The site also contained a cluster of strongly magnetic discrete anomalies surrounded by magnetic debris. Although these may be modern in origin, iron tap slag was noted on the field surface in the vicinity of these anomalies, and this may indicate early industrial activity.
