Studying Rocks

I’m heading off to study rocks at the Wilderness Center.
I’m checking out small pieces of coal.
The area around here used to have lots of coal .
Most people around this area in the past had coal furnaces
to heat their homes.
Pretty erratic rock.
So many different rocks to look at and read about.
Looking at the coral display.
I have seen so many different rocks.
Read so much information.
I hope I can remember some of what I’ve read.
If not I can always come back.
