Abstract: |
This report presents the results of a magnetometer survey. It has been prepared for SLR Consulting Ltd on behalf of clients. Part of the current site was surveyed by Substrata on behalf of SLR in December 2013 which was reported in Dean (2014). The data and interpretation of this part of the site has been incorporated in this report. The magnetic responses across the survey area were sufficient to be able to differentiate between anomalies representing possible archaeological features and background magnetic responses. Thirty-nine magnetic anomaly groups were mapped as representing possible archaeological deposits or features. Six of these anomaly groups represent former field boundaries recorded on historic maps. One group represents a track and footpath recorded on historical maps. One group may represent double curvilinear deposits typical of a former track. One group may represent a curvilinear deposit which may have archaeological significance although this is not certain. The western end of one group appears to show a collection of postholes, pits or tree bowls aligned with the footings of a former Devon bank field boundary. Alternatively, the aligned anomalies may represent the remnants of a once continuous pair of ditches flanking the Devon bank that have been subjected to later ground disturbance. The remaining groups are most likely to represent linear and disrupted linear deposits, such as former ditches or banks, of unknown period and from one or more phases of past land management. |
