Post medieval coal workings are visible as earthworks on historical air photos. They are located in the fields around Hawthorn Cottage. At NZ2574 8840 small rows of pits can be seen and at NZ2579 8869 more amorphous and converging pits are visible. In between these and in in other areas the ground surface is dotted with small low spoil heaps. The pits and spoil appear to be cut by post medieval ridge and furrow. Some of these remains survive as earthworks but some areas have been destroyed by open cast coal mining.
