Geophysical Survye Report Generally, anomalies identified through the geophysical survey are considered to relate to agricultural or geological activity. Three possible regimes of regularly spaced linear anomalies were identified within the survey results, along with two former field boundaries. Anomalies associated with a former stream that was culverted towards the end of the 19th century appear in the south of the survey area, as well as several broad anomalies that are likely to relate to natural pedological deposits belonging to the pre-channelled route of Sudbury Beck, which presently forms the southern extent of the site.
