Geograph - photograph every grid square

The radio/mobile phone mast is at the centre of the view but this picture is all about the old lead workings which have followed the deposits up and down the hillside known as Tides Low. (Low means hill in this part of Derbyshire.) "Tideslow Rake is the largest surviving site in the South Pennines where an open vegetation characteristic of substrates rich in heavy metals (in this case principally lead) occurs."

I can do no better than link this picture to a much more detailed explanation than I could possibly give. See: Link (Archive Link )
