Thornborough Northern Henge, West Tanfield, North Yorkshire: Report on Geophysical Surveys, July 2024
Author(s): Megan Clements, Neil Linford, Paul Linford, Andy Payne
Earth resistance (0.54ha), caesium magnetometer (5ha) and Ground Penetrating Radar (GPR) (5.2ha) surveys were conducted in the field immediately to the north of the Thornborough Northern henge to investigate the area for possible buried archaeology ahead of plans to improve visitor access to the site by the English Heritage Trust. The surrounding landscape contains an important prehistoric monument complex incorporating features of Neolithic and Bronze Age origins, including the three large Thornborough henge monuments. Anomalies detected by all three geophysical techniques suggest the Northern henge extends into the survey area. The surveys have also identified a series of pits and possible pit alignments that may have archaeological significance, in addition to the former gravel haul road and anomalies related to recent agricultural activity. Field work for the survey was conducted in July 2024.
