RockHoundR is the map every rockhound, prospector, and fossil hunter has been waiting for. Find collecting sites, know where it's legal to dig, check for mining claims, and keep a log of every find, all in one app.
DISCOVER THOUSANDS OF SPOTS
Browse a curated map of rockhounding spots and fossil sites across the country. Tap any pin to see what's been found there, how to get there, and whether it's open to the public. Filter by best spots, public access, or the material you're after.
KNOW WHERE YOU CAN LEGALLY COLLECT
Turn on land layers for BLM, National Forest, National Parks, and more to see which areas allow casual collecting and which don't. Tap anywhere on the map to see who manages the land, with the field office phone number and website.
SEE EVERY MINING CLAIM
Collecting on someone's active claim can get you in real trouble. With Pro, see active mining claims on the map, tap one for its serial number, type, and status, and see claims that have been closed.
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
• The source of the record
SEE THE ROCKS UNDER YOUR FEET
Turn on the geology layer to see surface rock colored by age, from Precambrian to today. Tap an era to learn what to look for there.
PLAN YOUR TRIP
Check the weather at any site before you drive out. With Pro, see wildfires, snow, and rain on the map. Find nearby fuel, restrooms, water, and campgrounds so you know what you're walking into.
YOUR COLLECTION
Log every find with photos, location, and notes. Finds are private by default, and you choose who sees each one. Add catalog numbers, weights, and sizes to keep your collection organized.
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, and see the distance.
OFFLINE-READY
Download map areas before you head into the field. Cell service is rare where the good rocks are, and RockHoundR keeps working when your signal doesn't.
JOIN THE COMMUNITY
Share finds, follow other rockhounds, and get help naming a mystery rock. Find a rockhounding club near you or start your own, with field trips and events in one place.
