So awhile back I decided to check out this really cool geological park known as the Bear's Den. There were several granite pegmatite outcrops at this location, which formed small cave-like openings (which I assumed were brought there by the glaciers 20,000-ish years ago since they were displaced and at random locations). Granite pegmatite's composition primarily consisted of quartz, potassium feldspar, muscovite mica and black tourmaline (schorl). I chipped a few black tourmaline specimens out, just to further add to my collection. Once it warms up, I'm going to make a trip out there again, but the weather hasn't been cooperating.
Here's some pictures that I took of the specimens and the trip:
And idk, this current event reminded me of the trip out there and I kinda wanted to share my discoveries, even if it's not such a big deal.
I can think of a few other locations in the US where you can find different varieties of tourmaline (like the super expensive watermelon tourmaline for example). Sadly, black tourmaline is pretty common. Probably as common as those orange tourmalines in game, haha.

Anyway, what about you guys? Does anyone else go out collecting? If so, find anything cool? Find any tourmalines?
