Full description

Devon County Council, 1838-1848, Tithe Mosaic, approximately 1838-1848 (Cartographic). SDV349431.

The visible earthworks did not correspond with any depicted pit.

Ordnance Survey, 1880-1899, First Edition Ordnance 25 inch map (Cartographic). SDV336179.

The visible earthworks did not correspond with any depicted pit.

Royal Air Force, 1947, RAF/CPE/UK/1974, RAF/CPE/UK/1974 RP 3450-3451 (Aerial Photograph). SDV356127.

A sub-oval earthwork pit was visible west of a relict field boundary. Map object based partly on this source.

A sub-oval earthwork pit was visible east of a relict field boundary. Map object based partly on this source.

Next Perspectives, 2010, Aerial Photography for Great Britain, Next Perspectives APGB Imagery ST1101 22-MAY-2010 (Aerial Photograph). SDV356259.

A sub-oval earthwork pit was visible east of a relict field boundary. The pit to the west has probably been levelled.

Ordnance Survey, 2016, MasterMap (Cartographic). SDV359352.

The eastern pit is depicted as an earthwork.

Hegarty, C. + Knight, S. + Sims, R., 2016-2018, The Blackdown Hills AONB and East Devon River Catchments National Mapping Programme Project (Interpretation). SDV359463.

Two broad but shallow pits circa 50 to 60 metres across are visible as earthworks on aerial photographs of 1947 onwards and digital images derived from lidar data captured between 1998 and 2014. The visible earthworks did not correspond with any pit features depicted in this location on the 19th century mapping available to the survey. This supports the interpretation that the visible earthworks are the remains of extractive pits that had passed out of use prior to the mid-to-late 19th century. The eastern of the two survives as an earthwork but the western has probably been levelled.
