Being a rockhound means always researching the next great spot to go mineral hunting. Since I was taking the time to enter locations into my GPS I thought it’d be nice to share this resource and save you the work. Most of these locations are primarily sourced from a few key books: Gem Trails of California, Gem Trails of Nevada, Rockhounding California and Rockhounding Nevada. Sites derived from these source books have entries referencing the book and page number for more detailed information. I plan on expanding the map to include sites in California, Oregon and Utah in the future and will also be integrating a form for submitting your own locations. We really hope you enjoy the map and get some use out of it! Please give us your feedback, comments and any missing locales.
