Abstract: |
A detailed gradiometer survey was conducted over land off Saundercroft Road, near Ottery St. Mary, Devon. The site comprises eight arable and pasture fields to the south of Saundercroft Road. The site lies on the southern flank of a low hill, sloping gently downwards from northwest to southeast. The gradiometer survey covered 25.4ha. Across the western and northern parts of the site, linear anomalies were identified that are likely to represent parts of former field systems. In places, the anomalies extend from junctions in existing boundaries, supporting this interpretation. Whilst it has not been possible to date these former boundaries, it is likely that they relate to historic subdivisions of the existing field system. Elsewhere, other linear anomalies and isolated pit-like responses may be of possible archaeological interest, although their origin is unclear; typically they are not clearly defined and appear to be randomly distributed. Ploughing trends appear in each of the survey areas, generally oriented parallel with the longest boundary in each field. Their responses are more clearly defined in places, which may be the result of near-surface geology being ploughed to the surface. A curvilinear anomaly towards the southeastern corner of the site is characteristic of a former channel, with its broad response and poorly defined extents supporting its interpretation as a naturally occurring feature. A number of regions of magnetic disturbance have been identified. The strongest of these are centred upon pylons located in the field boundaries and the disturbance extends some 60m in diameter; two other anomalies consistent with former pylon bases have also been identified in the northern survey area. A further region of magnetic disturbance lies close to a small wood near the centre of the site and is thought to be associated with the backfilling of a former pond or quarry. |
