Historic England's Aerial Mapping and Field Survey of Warton Crag Hilltop Enclosure - Full Report - Research Report 2017
Historic England’s Aerial Mapping and Field Survey Report of Warton Crag Hilltop Enclosure (Research Report 33/2017, Final Version 53 pages, 67mb downloadable pdf). This report of 2017 assesses results from previous surveys of Warton Crag, which historically was thought likely to be an Iron Age hillfort. Using the results from the 2016 high definition LIDAR aerial survey plus their own field observations, Historic England concludes that the site is likely to have originated earlier than the Iron Age, and was probably not defensive in nature. However nothing will be sure without proof from some future excavations ( if any ! ).
