NHER 4997 (Monument record) - Post-medieval quarries and possible flint mine

F. N. Hawards 'suspected flint mines' (polished axes etc). Flint mining industry all over this area.
R. R. Clarke (NCM).

February 1998. Walkover Survey.
Rapid Earthwork Identification Survey (Compartment 1013).
At least two large pits and a number of smaller pits were identified. The majority took the form of "long, wide trenches with deeper portions". Recorded sizes varied from 30m wide and 4m deep to 7m wide and 1m deep. No additional evidence for Neolithic flint mining was observed. A pit is marked in thie area on the First Edition Ordnance Survey map (S3) and these earthworks may relate to later flint mines or marl or gravel extractoin pits.
See report (S1) for further details.

October 2014. Breaking New Ground field visit. HA 32.
A group of pits and hollows, some circular, others very irregular in shape.
The maped extent has been revised to cover the whole area of earthworks. The site was previously mapped as a point at TL 7780 9328.
Most of these features were probably excavated to extract sand and gravel.

April 2019. Breckland National Mapping Programme
Earthworks probably relating to post-medieval extraction have been recorded from field visits and visualised lidar data (S2). The feature consists of a large area of extraction centred at TL 7775 2933 and a large pit centred at TL 7753 9326. The site has previously been interpreted as being Neolithic in date, however these features most likely relate to post-medieval sand or gravel extraction and are recorded on the First and Second Edition Ordnance Survey map (S3-S4).
The mapped extent of these earthworks has been refined based on the lidar data [1].
