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.
