Abstract:

This report presents the results of an archaeological magnetometer survey and, in the light of this magnetometer survey, the re-interpretation of a resistance survey previously undertaken along the northern edge of the magnetometer survey area. Seventeen magnetic anomaly groups were mapped as representing potential archaeological deposits or features. One of these groups partially coincides with, and likely represents, the western side of the cropmark-defined southern boundary of Clovelly Dykes hillfort. It does not follow the cropmarks north-eastwards to re-join extant banks of the monument and appears to have a slight curve south-eastward at its eastern end. Two groups may represent ring ditches. One group may represent a routeway of unknown date. Speculatively, three linear anomalies may represent sections of an enclosure abutting the Clovelly Dykes southern boundary. The remaining anomaly groups have characteristics typical of fragmentary remains of field and enclosure boundaries of unknown date. In the previously completed resistance survey dataset, some curvilinear anomaly groups were suggestive of stony banks with flanking earthen deposits which were interpreted as a possible, partial mirroring continuation of the Clovelly Dykes extant features. In the light of the current magnetometer dataset, some of the curvilinear resistance anomalies are more likely to represent near-surface geological patterns and the remainder of these are of uncertain provenance with a geological or archaeological origin possible. One resistance anomaly group is likely to be associated with the southern boundary of the Clovelly Dykes monument.
