I only know that because I went to the "Mineral Discovery Center" south of Tucson.

The other thing I learned was "Don't get run over by a mine truck!"

So, those are the two important things I learned there. My brain is just a big old bucket of useless knowledge. Although if I ever am at a mining truck accident, while they are waiting for the coroner, I can say.
"HEY! Those aren't headlights!! Those are air cleaners!" and it will sound like I really know what I'm talking about.
