Features & Capabilities

Identify rocks from a photo, explore the new Rock Encyclopedia, and discover better rockhounding spots with improved map filters.

RockHoundR is the map every rockhound, prospector, and fossil hunter has been waiting for. Find collecting sites, know where it's legal to dig, and keep a private log of every find, all in one app.

DISCOVER THOUSANDS OF SPOTS Browse a curated map of rockhounding sites across the country. Tap any pin to see what's been found there, how to get there, and what conditions to expect.

KNOW WHERE YOU CAN LEGALLY COLLECT Toggle land overlays for BLM, National Forest, and National Parks to instantly see which areas allow casual collecting and which don't. Avoid trespassing on private land or restricted parcels before you ever leave the truck.

DETAILED SITE INFORMATION Every spot includes: • What rocks, minerals, and fossils have been found • Land agency and access rules • GPS coordinates and directions • Weather and trip-planning info • Notes from other rockhounds

PLAN YOUR TRIP Check the weather at any site before you drive out. See nearby amenities like gas, food, lodging, and restrooms so you know what you're walking into.

YOUR PERSONAL FIND LOG Save spots you've visited, mark favorites, and keep a private log of your finds. Your saved spots stay on your device. Your secret locations are yours alone.

DRAW YOUR OWN ROUTES Draw lines on the map to mark trails you've walked, ground you've covered, or routes you want to come back to. Color-code them and save them privately.

OFFLINE-READY Download map regions before you head into the field. Cell service is rare where the good rocks are, and RockHoundR keeps working when your signal doesn't.

WHO IT'S FOR • Rockhounds and gem hunters • Fossil collectors • Prospectors and gold panners • Mineral and crystal collectors • Geology students and educators • Anyone who likes spending a Saturday outside with a hammer

Whether you're chasing agates on the Oregon coast, prospecting in the Mojave, or hunting Herkimers in upstate New York, RockHoundR puts the whole country's collecting map in your pocket.

Download RockHoundR free. Browse the full map, save spots, and log your finds at no cost.

Been rockhounding for about 6 years now, mostly in Arizona and New Mexico. Tried a bunch of apps before this one. This app just works, clean, fast, no weird stuff.
