A detailed magnetometer survey was conducted at Staggs Farm, Great Dunmow. An area of possible later-prehistoric or Romano-British settlement activity is visible in the form of small, adjoining enclosures while further linear anomalies could have archaeological origins. Plough effects are visible in the east, and two old field boundaries, visible on historic mapping, have been identified. The remaining responses include magnetic disturbance from nearby ferrous metal objects and areas of natural magnetic variation.
