Thread: You found what? Over where?

So, a week and a half ago, I was in northern Minnesota, in the Iron Range, known for its iron ore mining. Now, it's all surface mining. But years ago, there was a mine at Tower/Sudan that was deep - like wake up a Balrog deep. Anyways, as I took my small family on a tour of this mine, I saw some of the stones lining the mine walls half a mile under ground, a different type of stone. In one spot, the tour guide pointed it out because water smoothed out the surface. Apparently it's Ely Greenstone, called such because of its color, and location where found - not in that order. Super old. Super hard. Kinda green.

I asked, "how can I get a couple pieces?" To which they replied "it's a federal crime to take any out of the mine." Well. There goes that idea. Or does it? Now, don't get me wrong, I did not take any from out of the mine...but they have recently excavated for a science lab, and deposited a bunch of the stones in the parking lot as fill. They also said those, were not protected. Score.

now, I've been too busy to take photos of the actual stones I snagged, but these are VERY similar:
