I've always been fascinated by rocks and fossils -- some people call it "rockhounding". Are you familiar with the term (or hobby?!)
Heard of it but would love to know what it means?
It's basically the study and collecting of rocks and mineral specimens for fun.
Ok so its like amatuer geology?
*Exactly* the name for it. Basically, the first amateur geologists were prospectors looking for valuable minerals and gemstones to make money.
Are there any laws in place regarding the collection of rocks and minerals from public areas?
Depending on where you are -- definitely! Tourist info centers and chambers of commerce can provide good intel as to what's allowed where. But I do know some state parks have *strict* rules against it.
