It would be nice to see a positive date(s) put to this site. Unfortunately, modern archaeology is, by its very nature, destructive. Whether this would lead to issues, due to the fell lying within the Lake District National Park, is an obvious concern. I would expect that the site would have to be restored to its original condition, as the thin soils on the Cumbrian mountains are easily eroded by weather. The erosion caused by walkers and climbers highlights this.
