Spoil heaps and extractive landscapes surrounding Grimethorpe and Ferry Moor Collieries. The collieries expanded to this size by the 1960s. Grimethorpe was closed in 1992 (Hill 2001, 161) but much of this area has since been used for opencast reclamation of the spoil heaps. There is no legibility of the former enclosed landscape. The fields shown on historic maps are fairly regular and probably late in date, however, this area is likely to have been assarted from woodland although parts of the land may have been enclosed from the edges of the Cudworth open field system.
