This zone is predominantly found across the coal measures in the districts of Barnsley, Rotherham and Doncaster, with some outlying areas on Doncaster’s gravels and sandstones. In the past extractive industries dominated the landscapes of South Yorkshire. This zone represents the collieries and large quarries active in 2003. These sites often contain large spoil heaps, winding gear and surface structures.
