NHER 65950 (Monument record) - Undated ditch and potentially post-medieval extraction pit

May 2020-January 2021. Geophysical Survey.
Magnetometer survey of site on proposed route of onshore cable for Norfolk Vanguard and Boreas Offshore Wind Farms (Area 202).
This survey identified no potentially archaeologically-significant anomalies.
Although various discrete patches of magnetic enhancement were recorded, these are all thought to be the result of variations in the underlying geology.
Areas of magnetic disturbance at the margins of the field and scattered dipolar anomalies were all probably caused by ferrous material on or close the surface, most likely modern debris.

October 2020-June 2021. Trial Trenching.
Evaluation of site on proposed route of onshore cable for Norfolk Vanguard and Boreas Offshore Wind Farms (Area F202; Trench 256).
The single trench excavated at this location revealed a north-north-east to south-south-west aligned ditch and a large probable extraction pit, neither of which produced any dating evidence. A large 'sand pit' is though marked to the south-east on the Ordnance Survey First Edition Six-inch map (S1), suggesting the pit was most likely associated with post-medieval quarrying.
