The Forest of Dean is full of evidence of past coal mining. This old spoil head in Whitecroft, although overgrown, contains some excellent shale full of fossil plants. It is a shame the site is so overgrown, which means you will need to do some digging. Carboniferous, Spoil, Rating: ♦♦♦
When visiting the village of Dalmellington, you cannot help but see the huge spoil heap. This is now disused, but contains plenty of material to search through, including black shale that is rich in fish remains. Plant remains can also be found. Carboniferous, Spoil Heap, Rating: ♦♦♦♦♦
