A magnetometry survey by K Armstrong of Tigergeo confirmed the location of the known glass-working site together with possible traces of associated woodland exploitation in the north-west of the site. Centrally, various linear anomalies may relate to further industrial use of the woodland, while known former field boundaries and trackways were located to the south-east. In the same area, an undated complex of possible linear enclosures and circular anomalies was discovered that may relate to settlement or farming activity. Traces of cultivation were also discovered in the area but on a different alignment to the ditched enclosures.
