Topsoil magnetic susceptibility was tested at 10m intervals in a 100m wide transect N-S along the edge of the gravel terrace. Following this fluxgate gradiometer survey was applied to the only two fields to show enhanced MS, which included one of the finds clusters detected by fieldwalking. Prior to excavation, two further blocks of fluxgate gradiometer survey were carried out on the other two RB pottery clusters detected by fieldwalking, in order to determine the presence of features and aid trench location. (1) Grid ref centred. See E9458 for trial excavations, E9460 for fieldwalking.
