 There is evidence of settlement in the Heacham area over the last 5,000 years, with numerous Neolithic and later Bronze Age finds within the parish.This is presumably because the local geology consists of primarily cretaceous sands and underlying chalk, meaning that there is very little surface water for miles in any direction.This can also be seen along the banks of the Caudle Carr, just outside Dersingham, where numerous archaeological finds have been made.
