The site lies on the north-eastern periphery of Sutton in Ashfield, close to Mansfield. The King’s Mill Reservoir lies at the junction of the A38 / A6075 / A617 and B6139, with the site accessed through the existing Mill Adventure Base which lies north of the A617 Sherwood Way south. The site comprises a triangular plot of c.3.9 acres of pasture with the reservoir to the northwest, the railway line to the east and the Mill Adventure Base to the south. The evaluation comprised six 30m x 2m trenches. Trenches were positioned according to a plan presented in the approved WSI. Final trench locations were recorded using a GPS accurate to 0.03m. The results of the evaluation confirm, as expected, the remains of the sandstone bed of the horse-drawn railway line that ran through the site in the early 19th century. Contained within a construction trench with flanking gullies that were probably to assist in drainage and stability of the track, the sandstone gravel is consistently present across the three interventions, possibly showing evidence of erosion and displacement of the gravels during its use or perhaps the gravels were robbed out for a later use; for example as part of the altered railway line along the eastern site boundary in the mid 19th century. Although no dating has been recovered, the position, alignment and characteristics of this feature correspond with the known position of the extinct railway. The only other feature encountered in this evaluation was an isolated pit in one pit. This ash, charcoal and sand filled pit was also undated. Plant macrofossils of wild tree and grass species were identified in the sample but no cultivated cereals which might have indicated dating. The lack of cultivated cereals does not automatically infer that there was no agriculture in the area at time of deposition, simply that no seeds or chaff were incorporated into the fuel for the fire which resulted in the charcoal in this deposit. With no other evidence this pit remains undated, but is tentatively considered most likely post-medieval or modern in date simply due to proximity to the railway lines.
