Metal detecting laws in Wyoming generally prohibit recreational metal detecting within the state.
State parks do not allow hobbyist detecting, and the use of metal detectors is primarily restricted to official purposes such as locating lost personal items, which requires specific permission.
These restrictions protect Wyoming’s unique historical and environmental resources.
Wyoming’s saving grace is its enormous federal land holdings. BLM land covers approximately 18 million acres of the state, and extensive National Forest land (Shoshone, Bridger-Teton, Bighorn, Medicine Bow) adds millions more.
Gold prospecting and casual detecting on BLM and USFS land under casual use rules is legal. Like Montana (state parks banned, BLM open) and Idaho (park manager permission required, BLM open), Wyoming’s federal land access compensates for restrictive state rules.

Metal Detecting Laws and Regulations in Wyoming
Metal detecting laws in Wyoming restrict the hobby on state-managed land but provide federal land access. Here is the breakdown.
State Parks (Generally Prohibited)
Wyoming generally does not allow recreational metal detecting in state parks. The use of metal detectors is primarily restricted to locating lost personal items, and even that may require specific permission. There is no permit program for hobbyist detecting in state parks.
BLM Land (~18 Million Acres)
The BLM manages approximately 18 million acres in Wyoming. Recreational detecting and gold prospecting are allowed under casual use rules. Hand tools permitted; refill all holes. ARPA prohibits removal of artifacts over 100 years old. Contact the local BLM field office (Casper, Rawlins, Rock Springs, Lander, Worland, Buffalo, Cody, Kemmerer, Newcastle, Pinedale) for area-specific rules.
National Forests
Wyoming has extensive national forest land: Shoshone, Bridger-Teton, Bighorn, and Medicine Bow-Routt. Casual detecting in developed recreation areas is generally allowed. Gold prospecting with hand tools is permitted under casual use. ARPA restrictions apply.
NPS Sites (Prohibited)
Yellowstone National Park, Grand Teton National Park, Devils Tower National Monument, Fort Laramie National Historic Site, and Fossil Butte National Monument are all off-limits.
Private Land
Private land with written landowner permission is the primary option for relic hunting. ARPA does not apply. Wyoming’s vast ranches have Oregon Trail, Pony Express, frontier fort, and cattle ranching history. Building relationships with ranch owners provides access to historically productive private land.
Rules Summary
| Land Type | Detecting Allowed? | Permit/Permission | Artifacts |
|---|---|---|---|
| State Parks | Generally no | N/A for hobby detecting | N/A |
| BLM Land | Yes (casual use) | No permit for casual use | ARPA (100+ year rule) |
| National Forests | Developed areas; casual use | Check with Forest Supervisor | ARPA restrictions |
| NPS Sites | No | N/A (prohibited) | N/A |
| Private Land | Yes | Written landowner permission | Finder keeps (per agreement) |

Best Metal Detecting Locations in Wyoming
- South Pass area BLM land (Fremont County) – Site of Wyoming’s 1867 gold rush. South Pass City is now a state historic site (off-limits), but surrounding BLM land in the gold district offers prospecting. Check claim status. See our gold panning laws in Wyoming page.
- Oregon Trail corridor private/BLM land (various counties) – The Oregon Trail crossed Wyoming from east to west. Register Cliff, Independence Rock, and other landmarks are documented. BLM land and private land along the trail produce frontier-era items.
- Fort Laramie area private land (Goshen County) – Fort Laramie NHS is NPS (off-limits). Private ranch land near the fort and along military roads produces frontier military artifacts from the 1840s-1890s.
- Bighorn Mountains BLM/USFS (various counties) – Gold prospecting in the Bighorn Mountains on Bighorn National Forest and BLM land. Mining-era history from the late 1800s.
- Wind River Range area (Fremont, Sublette Counties) – Gold districts and mountain man fur trade history. BLM and Shoshone/Bridger-Teton NF land for prospecting. Remote but historically rich.
- Casper area (Natrobe County) – Oregon Trail and Pony Express history. Oil boom town history (1890s onward). Private land and city parks (check rules) near old trail crossings and military sites.
- Cheyenne area (Laramie County) – Wyoming’s capital and a major railroad and military town from the 1860s. Private land near old town sites and Fort D.A. Russell (now F.E. Warren AFB) area.
- Eastern Wyoming BLM (various counties) – Vast BLM land with ranching, homestead, and frontier military history. Old ranch headquarters, line camps, and stage stops on federal land.

Wyoming’s History and What You Might Find
Wyoming’s European history centers on the fur trade and emigrant trails. The Oregon Trail, California Trail, Mormon Trail, and Pony Express all crossed Wyoming. Frontier forts (Fort Laramie, Fort Bridger, Fort Fetterman, Fort Phil Kearny) protected emigrants and later fought in the Indian Wars. The South Pass gold rush of 1867 brought miners. The transcontinental railroad crossed southern Wyoming in 1867-1869. Statehood came in 1890.
Wyoming’s ranching heritage includes the Johnson County War (1892) between cattle barons and homesteaders. The state’s wide-open spaces have preserved frontier-era items well in the dry climate.
Common BLM and private land finds include gold (South Pass, Wind River, Bighorn areas), Oregon Trail emigrant items (buttons, buckles, ox shoes, coins), frontier military buttons and cartridge casings, Pony Express station items, ranching-era hardware, and railroad-era artifacts.
Tips for Metal Detecting in Wyoming
- Focus on BLM land. Wyoming’s 18 million acres of BLM land are your primary detecting resource. Learn the BLM land status maps for your target area.
- Do not detect in state parks. Wyoming’s restrictions are clear. Focus on BLM, National Forest, and private land.
- Check mining claim status for gold prospecting. Wyoming’s gold districts have active claims. Use the BLM LR2000 database before prospecting.
- Plan for remoteness and weather. Wyoming is sparsely populated and weather can change rapidly. Bring extra fuel, water, food, warm clothing, and communication equipment. Cell service is limited outside towns.
- Research the Oregon Trail. The documented trail corridor across Wyoming is one of the most significant frontier detecting opportunities in the West. BLM land and private ranch land along the trail produce emigrant-era items.
- Build ranch relationships. Wyoming ranchers control vast acreage with frontier and ranching history. Approach respectfully and explain the hobby.
- Use a gold detector in mining districts. Wyoming’s mineralized mountain soils require pulse induction or high-frequency gold detectors.
- Detect June through September. Wyoming’s short summer season limits detecting. High-elevation areas may not be accessible until July. Snow returns early in the mountains.

Conclusion
Metal detecting laws in Wyoming restrict state park detecting but provide 18 million acres of BLM land and extensive national forest for casual detecting and gold prospecting. The Cowboy State’s Oregon Trail heritage, frontier forts, and gold rush history make BLM and private land detecting productive for those who prepare for the remoteness and plan their trips carefully.
This is a fitting final state in our 50-state series. Wyoming’s wide-open BLM land, frontier history, and gold prospecting opportunities embody the adventurous spirit of metal detecting at its best.
