Description

Hanger Hill is situated on a ridge of high ground between the Maun Valley to the South and the valley of the River Meden to the north. An area of 60m x 60m was surveyed over the course of two seasons. The survey area contained nine 20m x 20m grids, and was located on the north-eastern side of Hanger Hill in Budby parish. Tapes were aligned across the top and bottom of these grid squares, and tapes were set as walking guidelines at 1m intervals at 90° to the baseline, beginning at the 0.5 metre mark. 1 metre transects were walked using the RM15. Data was collected in parallel mode, at 0.5m data collection intervals along the transects. Trees and other obstacles were avoided and a no-data value was given. The results from the survey are extremely interesting, with strong areas of high and low resistance representing a number of archaeological features. The area of the pot-boiler stone spread can clearly be seen and has a well defined extent and apparent shapes within it. It is possible to identify in the resistance data many of the features which are visible as earthworks, and/or detected in previous geophysical survey. These include the circular enclosure; this bank and ditch can be seen as a low resistance feature (the ditch) and high resistance (internal bank). The summit of Thynghowe-identifiable as a high resistance anomaly. Also the Warsop and Edwinstowe / Birklands boundary ditches seen as linear low resistance anomalies. Furthermore, the results from excavations in 2016 suggest that the area of very low resistance towards the summit is a natural geological deposit. If we assume that the excavated area in one trench is reflective of the entire deposit of the feature, then this feature represents an archaeological deposit of pot-boiler stones. It is is similar in shape and size to two other features. We can therefore cautiously suggest that these high resistance features may also represent deposits of pot- boiler stones. It is possible that this entire high-resistance area encountered in this survey represents deposits of pot- boiler stones.
