Metal detectors are allowed in national forests areas that don’t contain historic or archeological sites or resources. Generally they can be used in developed campgrounds and recreation areas, swimming beaches and picnic grounds. Signs are posted at some but not all off-limits locations.

The U.S. Forest Service recognizes fur types of metal detector use, some of which require permits.

• Hunting for hidden treasure, such as jewelry, money and precious metals
• Prospecting for gold and other mineral deposits
• Searching for historic or prehistoric artifacts
• Recreation, such as looking for items less than 50 years old that have no historical value.
