Can I bring rocks to be identified? And is there an admission fee if you just want to do that?

They do identify rocks and the gift shop is where you could find someone for that which is free. Only admission fee for the museum.

Yes you can. I brought something and they were able to identify it for me. Great rock museum. BIG collection of fascinating rocks. Go and have a rock & roll time. Lol.

Yeah, just ask at the gift shop counter and they will find someone who can answer, no charge.

I think you can and probably not.
