yup. Abandoned mine - a photo on Flickriver

            This was a happy day. This the place the guy at Walmart Pond told me about, the crystal cave. It's been picked clean as far as I could see, but still a happy day for me. The first one the city hadn't got to first and filled in (edit - they did, actually, just partially eroded back out, was a large moist mine tunnel). That not mafic, that felsic rock. Yet Cowles mountain right by it, those hills you can see the mafic construction, and the columnar jointing on some. So possibly this is a result of boundary issues. Hmm. 

Research online indicated that this was an extensive pre-Columbian mine. Folk have said it used to be very extensive, and this is it after being filled in. I've never been able to find out what was extracted online, but the immediate area is super-abundant in black tourmaline and (mica mud?). Locals have mentioned multi-color tourmaline. Have also seen multiple mentions online that it was a government thorium mine. Did get repetitive nosebleeds the day after crawling in there for a while. Dunno. 

If you want to get here I have the location mapped. If I ever find out what was miined here I'll update and post up the info.
