Rockhounding in Wyoming depends on the exact property and land manager. This database currently models 6 Ready, 12 Conditional, 28 Research-only, and 0 Protected/viewing records. A map pin or directions link is not permission to collect.
Where can I go rockhounding in Wyoming?
The strongest current leads are the records classified Ready or Conditional. Ready means the modeled activity is currently supported by the evidence; Conditional means a named condition still has to be verified.

Is rock collecting legal on public land in Wyoming?
There is no single statewide “yes” that applies to every public parcel. Rules depend on the exact land unit, land manager, resource type, collecting method, claims, closures and permits. The database therefore refuses to inherit broad permission from a state, agency or nearby parcel. Check the record’s status reason and primary blocker, then verify the current rule for the exact place before collecting.
What research-only or protected places are on the map?
Research examples
- Laramie Mountains — Jade Research Explainer — Albany/Converse. WSGS references nephrite deposits in the Laramie Mountains; exact modern collecting footprint and rights remain unresolved. Context: Wyoming State Geological Survey research context.
- Red Gulch Dinosaur Tracksite — Vertebrate Track Viewing Control — Big Horn. Red Gulch is a managed vertebrate tracksite. The database never converts general BLM common-fossil rules into permission to remove vertebrate tracks or material from the developed/special site. Context: Bureau of Land Management — Wyoming.
- Seminoe Mountains — Jade Research Explainer — Carbon. WSGS cites Seminoe Mountains jade research, but historic occurrence cannot establish current collecting permission. Context: Wyoming State Geological Survey research context.
- Atlantic City / Big Atlantic Gulch — 2026 Access & Prospecting Research — Fremont. BLM opened Atlantic City and Big Atlantic Gulch campgrounds for the 2026 season, confirming current recreation access. Campground opening does not establish gold-panning or mineral-removal authority across the historic district or active claims. Context: Bureau of Land Management — Lander Field Office.
- Green Mountain — Jade & Agate Research Explainer — Fremont. BLM says jade and agate occur in the surrounding areas and posts a Dec 1–Jun 15 seasonal closure, but “surrounding areas” does not define a lawful collecting footprint or resolve mineral claims. Context: Bureau of Land Management — Lander Field Office.
- South Pass Historic Mining Area — Gold Research Explainer — Fremont. BLM verifies the historic gold district, but the page is a historic/cultural recreation page rather than a modern recreational gold-panning authorization. Context: Bureau of Land Management — Lander Field Office.
- Wiggins Fork Agate — Research Explainer — Fremont. WSGS specifically illustrates Wiggins Fork agate; current land ownership, legal footprint and collection authority remain unresolved. Context: Wyoming State Geological Survey.
- Granite Mountains — Wyoming Jade Research Explainer — Fremont/Natrona. WSGS references established jade research in the Granite Mountains; current parcel, manager, mineral-right and claim-level collection authority is unresolved. Context: Wyoming State Geological Survey research context.
Why are county research records kept inside the atlas instead of becoming separate pages?
County-scale geology is valuable for discovery, but a county occurrence record is not automatically a field destination. Keeping broad research records inside the state guide and interactive map preserves their geological value without pretending that every county-level occurrence has unique public access, collecting authority or specimen-level coordinates.
Does the Wyoming map cover every county?
The current state layer reports 23 county or county-equivalent areas. County/context markers are intentionally distinguished from exact field coordinates.

How do directions work?
46 Wyoming records are navigation-active in this release. The interactive popup can open Google Maps, Apple Maps or OpenStreetMap. Exact coordinates are shown only where the database marks them safe; otherwise the navigation destination is a named place or county/context query.
Can I use Near Me for rockhounding in Wyoming?
Yes. The current Wyoming layer has 6 Ready Near-Me records. Near Me deliberately excludes Conditional, Research-only and Protected/viewing records.
How current is this Wyoming guide?
The latest evidence check recorded for this state is August 19, 2026. Treat that as the database review date, not a guarantee that nothing has changed since then.
What do Ready, Conditional, Research and Protected mean?
Ready supports the modeled activity on current evidence. Conditional requires a stated condition to be verified. Research is useful location/geology context without established collecting authority. Protected/viewing is not a collecting recommendation. These classifications are intentionally more conservative than a simple occurrence map.
