Some photos of that glorious piece of garnet mica schist I found on the hill behind my house:
There she is! Kitteh for scale.
And a shot through ye olde hand lens. Look! Garnets!
I have no idea where this thing actually came from. The hill behind my house seems predominately outwash, and there isn't bedrock around so far as I know. Certainly not bits of the metamorphic core. I'm wondering if someone just abandoned it, like people do puppies. No matter, it's got a happy home now.

I will be eternally grateful to her for writing these. A round of applause, please, my darlings, and if you're ever lucky enough to meet her IRL, be sure to buy her a drink. I owe her a few gallons, so I hope she's thirsty when we finally meet.
Don't be surprised if I post more photos of this find. These were shot in haste on my lunch break, and it deserves better. But several people have wanted to see it, and I just couldn't wait anymore.
