Evaluating Aggregate in North West England

Questions have been raised about the effectiveness of geophysical techniques as a means of evaluating archaeological remains in the North West of England. There have been sufficient doubts, in the judgement of some professional archaeologists, to abandon its use altogether. Others, however, regard geophysical survey as one of the key evaluation techniques and commission its use on many of their projects. Concerns over the effectiveness of geophysical survey in the North West are particularly significant since there are often no good alternatives.
