Semi regular straight sided enclosure boundaries subdividing larger sinuous enclosures typical of assarts. There is good survival of the irregular patterns amongst the more regular enclosure giving significant legibility of the assarted landscape. Also the pattern of the roads is very sinuous. Within the polygon were post-medieval coal pits and a sandstone quarry. Also a small late 17th century Colliery on the edge of the village of Thurgoland which was no longer marked on map by 1894.
