Those interested in mining in the Peak, may like to know that I have
uploaded quite a few 1899 25 inch Barmasters' maps to the Mine Explorer web
site some time ago. They have been scanned at a good resolution and you will
find them as PDF files. Not the whole of the Peak is included but, from
memory there are about 25 to thirty such maps. For example, go to Snake Mine
and here you will see one of the maps in question. There are many more
scattered about the site and I know that Bonsall is there too!
