Not actually filled with asbestos, or a mine – however we originally thought it was and feared we had given ourselves mesothelioma. This is a great tunnel to explore, filled with wooden support beams and a fibrous crystals on the walls called Flos Ferri (a form of aragonite).
Went there today and am now looking at more places to explore, very cool and also very typical that there was a sesh spot at the end with a tag saying try some meth.
Where is it?
