My bookshelf collapsed yesterday morning. In the debris I found these nice minerals that I collected a few years ago very close to the actual type-locality for this mineral. There were nice vein-like bodies of this mineral also accompanied by a number of other minerals. It was a bit of a risk collecting next to a big collaps funnel of old mine workings. So a piece of advise for all your mineral collecting fans - be careful, never collect alone, always have your cellphones with you!
