An extraction pit of possible post-medieval to modern date is visible as an earthwork pit on aerial photographs of 1946 onwards, to the northwest of Blackhill Reservoir. The irregular shaped earthwork pit measures approximately 75m in length by 29m in width. It is depicted as two small ponds on the First Edition Ordnance Survey map of between the 1880’s-90’s, although likely originated as an extraction pit or quarry, particular given that the surrounding area is characterised by gravel and marl pits. The earthwork pit is visible on Lidar-derived images of 2005.
