A detailed magnetometer survey was carried out at the former Elm Grove Nursery in Locking, North Somerset, ahead of a proposed residential development. The survey was conducted using a hand-pushed, cart-based system of 5 sensors space 0.5m apart. The survey located a number of linear, curvilinear and rectilinear anomalies that appear to relate to linear and rectilinear ditches and possible enclosures. The features are generally located towards the north western and south eastern corners of the site, but there are a number of weak and indistinct positive responses in between that may also relate to cut features.
