I was labeling my whole rock collection wrong for a solid year.
I was at a club meeting in Boise and showed off a piece of 'granite' I found near the river. This older guy, Frank, just squinted and said, 'Kid, that's not granite, that's a piece of quartz monzonite. Look at the pink feldspar.' I went home and checked my other labels with a hand lens. Turns out I'd been calling anything with big crystals 'granite' for months. How many of you have had a basic ID totally flipped on you like that?
