The book covers all periods of time from prehistory to the present, for a typical moorland walk might take in the standing stones of a prehistoric stone circle, a medieval boundary marker, a guide stoop dated 1709, the straight walls of nineteenth-century enclosure, a row of Victorian grouse butts, a long line of flagstones brought in by helicopter, and very much more besides. Some of this physical evidence remains puzzling, but most of it can be explained by assiduous research in local record offices. The author has not referenced the documents, as that would have made the book twice as long, but the bibliography provides leads to where the information may be found.
