I want to become a rockhound, but I am definitely an amateur geologist.
It is cool you can chose some recreation in geology. All you have to do is to collect rocks and mineral specimens from their natural environment.
But how do I identify them?
It is very simple, a collection can begin by simply picking up a rock.
I have some geodes, but when my friends ask me what it inside, I just say "pretty stuff."
You can have more friends that share common interest by joining clubs or groups that search for specimens and compare them in groups as a hobby.
That's a good idea!  Maybe a rock club could help me learn about my rocks!
You can also search for in Information on where to find such groups  at libraries, bookstores, and "gem and mineral shows".
