I'm doing a spot of research into lead speciation in relation to historic mining activity in the Dales. I'm currently trying to identify a suitable site but it's proving a little tricky. For example, I thought Faggergill might be a good option but there is little information online and I've not had any response from speculative emails. Another potential is Fossil Cave, which is a little easier to gather information about. If anyone has a good knowledge of the caves/mines in the Grassington Moor/Swaledale area, or can put me in touch with someone in the know then please feel free to message me. It would be greatly appreciated.
