Start With the We Lick Rocks Map
The quickest way to find rockhounding spots near you is the We Lick Rocks explore map. It shows GPS coordinates for hundreds of documented mineral localities across all 50 states. Just allow location access and zoom to your area.
Use the MRDS Database
The USGS Mineral Resources Data System (MRDS) is a free, searchable database of over 300,000 mineral occurrences in the US. Search by state and mineral type to get GPS coordinates for historic localities near your zip code.
Join Your Local Gem Club
The American Federation of Mineralogical Societies lists gem and mineral clubs in every state. Most clubs run monthly field trips to local collecting sites — often on private land not accessible to the public. Annual membership is typically $20–30.
Check BLM Land Near You
The BLM's "My Public Lands" web map shows BLM land boundaries overlaid on a regular map. Most BLM land allows casual rock collecting for free. Even in heavily populated states, BLM land is often within a 2–3 hour drive.
Road Cuts Are Underrated
Highway construction exposes fresh rock faces that are rarely visited. Legal road cut collecting varies by state (you must be outside the right-of-way), but exposed pegmatite, quartzite, and limestone road cuts can yield excellent specimens within miles of home.
