Washing Crystals in the Brine
This is a picture from our trip to Gem-O-Rama in Trona, California last October. These people are scrubbing Hanksite crystals free of the mud they grew in using a saltwater/brine solution. This is one of the best places to get crystals and see geology, as long as you don't mind getting really messy. The crystals grow underground amidst the mineral-laden mud, and to get these specific crystals they scoop big piles of the mud up and let people dig through them. It's kind of crazy.
