Identity HelpOrphan Girl Mine, Butte Montana unknown
14th Jun 2012 02:37 UTCKarl Volkman Expert
While working through several rocks from Orphan Girl mine in Butte, Dad found several of these crystals. They are on an unidentified red/brown mineral that coats pale pink rhodochrosites. The rock is from the 2011 crosscut constructed in the Orphan Girl. Crystals are no more then about 2mm long

Does it fluoresce under LW? It may be to small to detect fluorescence but if so, you might be correct about Cerussite.

Did it fluoresce under LW only, SW only or both? Also, if you have many of these minute crystal and don't mind sacrificing one to the acids gods, Cerussite should effervesce in dilute HNO3.

I found an odd pair of women's shoes at the bottom of the waste rock pile. They were probably 100 years old and were designed for someone with what was once called a "clubfoot".
I took the shoes down to one of the entrances to a building on the Montana Tech campus and placed them on the flat rails of the entry to one of their buildings. I left them right there, but I did take a creepy photograph of them. It was a 35mm slide, and will be hard to re-locate, but maybe worth the effort since there is some interest in the Orphan Girl on Mindat.
My interests these days is in early mining history of the U.S. Especially the experiences of children in mining camps. They had nothing to do but join gangs and get into mischief. Our Monte Cristo camp had many high angle tramlines. The kids would hide in the ore buckets and get a free ride up to the high peaks. There is an excellent book about those kids. Written by Elof someone. "The Coffee Chased us Up". Still don't understand the title.
