The Derbyshire Caving Club recently had a day out under the alien landscape of Parys Mountain, Anglesey.
Perhaps one of the more unusual mines, with evidence of some of the first mining from the Bronze age period, right up to fairly recent times, it has seen a long history, and produced huge amounts of copper.
Worth a note are the unusual conditions provided by sulphorous minerals, providing acidic water below a ph of 4! This in turns creates the perfect conditions for "extremophile" bacteria, and even turns copper carbonates back to high grade copper when all the conditions are met!
A big well done to Sam(2) for her first propper adventure underground! I think she found this quite the challenge!
Thanks to Sam, Kelly and Pete for the photos :-)
