Irregularly shaped pits and mounds are visible as earthworks on visualisations derived from lidar data captured between 1998 and 2017. The extensive earthworks occupy an area of circa 2.7 hectares of southwest facing slope, on the northeast side of the River Erme. They do not correspond with any pit and mound features shown in this location on the mid-19th century Parish Tithe Map and accompanying Apportionment, which records this area as comprising orchard (land parcel 26), wood (land parcel 1010) and coppice (land parcel 1016). Nor do the earthworks correspond with any features on later available historic maps. Transcription of these earthworks was carried out primarily using Simple Local Relief and Positive Openess lidar visualisations. Given their complexity and in places subtle nature, not all visible earthworks have been transcribed and an extent of area polygon has been used to define the approximate limit of the earthworks. Their character and form support the interpretation they represent the extractive pits, stream channels and associated spoil heaps of a medieval or post-medieval alluvial tin streamworks, which had passed out of use by the mid-19th century when the area was given over to woodland and orchard. The earthworks are not visible on other available aerial imagery owing to dense tree cover. Further investigations, such as targeted trenching is recommended to help define the character of these earthworks. A more extensive area of possible tin workings has also been recorded circa 50m to the north (MDV126213).
