Investigation of a Possible Neolithic Causewayed Enclosure at White Hall Farm, Isleham, Cambridgeshire

Aerial photographs taken during the dry summer of 2018 showed several concentric arcs of possible interrupted ditches across a peninsular created by the former courses of the rivers Snail and Lark. A series of 24 adjacent 30m x 30m grids were set out using the N-S field drain as the east boundary for field walkers. An E-W and N-S survey transect was undertaken using an Arrow GPS/GNSS antenae on a 2m pole and later compared to the 1m LiDAR DEM image. Due to a partial collapse of the field drain where the feature cut it, it was possible to investigate the exposed geology. Aerial photography crop marks together with the finds assemblage from field walking suggest that this may be a Neolithic interrupted ditch enclosure. Unusually it is sited on a peninsular, bounded on three sides by watercourses. The rich resources of the marshy fen edge and lagoon would have made it an attractive location for hunter-gatherers.
