Abstract: |
Eight magnetic anomaly groups were characterised as representing potential archaeological deposits. Of these, two anomaly groups are likely to represent the ditch of the enclosure that is the main target of this survey. There is a gap in the anomaly pattern representing the ditch on its south-western side that does not correspond to any gap in the enclosure earthworks recorded on a RCHME map of the monument. One group may reflect a stony deposit in this gap. It may reflect either the surface of an original gap in the enclosure ditch or a later in-filling of the ditch. A gap shown in the RCHME earthworks map on the enclosure's eastern side is not reflected by the geophysical survey data which shows the anomaly group representing the enclosure ditch as continuous at this point. Two anomaly groups may represent disturbed ground with archaeological material and another could possibly represent a sub-circular archaeological feature such as a ring-ditch although all three may represent natural deposits or ground disrupted during the clearance of the woods across the site. Two groups may represent disturbed ground and deposits associated with the ploughed-out enclosure bank. The anomaly groups representing the enclosure ditch do not coincide exactly with the earthworks of the enclosure as depicted on the RCHME earthworks survey but it is thought that the earthworks survey and this geophysical survey depict the same feature and that the geophysical data is likely to be more positionally accurate. |
