Evaluation by J Pine and A Weale of TVAS in advance of possible mineral extraction involved the excavation of 149 trenches. A high density of certain and probable archaeological deposits was revealed, with 60% of the trenches proving positive, although little cultural or environmental dating evidence was recovered from them. Where such evidence was present, the deposits reflected Early Neolithic and probable Middle to Late Bronze Age occupation, with prehistoric activity of other periods represented by a few pieces of possible Mesolithic flintwork, Late Neolithic and Late Iron Age pottery. Roman and medieval finds and deposits are very few, suggesting that the area was probably used as farmland in those periods. The evaluation was unable to confirm that cropmarks on the site were of archaeological interest or origin.
