Yes, they include that information in the docent led tours which i recommend.

Not alot about it there. You can ask them to show you where they have more information about it.
They often have volunteers who can talk on that topic as well as a "gold panning" trough where you can learn how to pan for "gold" (fool's gold/iron pyrite) and take a sample home.
