I had this old book when I was little. It was all about different kinds of rocks and minerals, and I would carry it around, and make notes about it, even though I couldn’t quite read yet. I came across these pictures the other day, and yup, rocks are still cool.

I was fascinated with rocks growing up, we has a friend who polished rocks, so I ended up with quite a collection which I still have to this day
