State-specific Mineral Maps
No matter what state you or your rockhound in is, there is a map just for you. Each state has a unique geology and this page gives options for each one. In addition to individual states, there are maps for the entire USA, the National Parks, and maps specifically for finding gold. Each map shows the different types of rock and mineral formations in the state or area and gives tips on where to find the best specimens in your state. Handy to have in the old pack, but in some cases, you may want to frame the maps, as they are professionally made and incredibly beautiful.
