Archaeology, Artifacts and the Law
Verdict summary
On US federal land, the Archaeological Resources Protection Act makes it a crime to dig up or remove archaeological resources more than 100 years old without a permit. National Parks prohibit metal detecting. State and tribal land have their own laws, and private land needs the owner's permission. Responsible hunters research first, get permission, and report significant historic finds.
Federal land.
The Archaeological Resources Protection Act of 1979 protects archaeological resources over 100 years old on federal and tribal land. Agencies such as the Bureau of Land Management and the Forest Service allow some casual activities, such as hobby collecting of modern coins or common rocks in some areas, but not the removal of historic artifacts.
State, tribal and private land.
State land rules vary widely and often require permits. Tribal land requires the tribe's permission. On private land you need the owner's written permission, and historic objects generally belong to the landowner.
How PinPoint Treasure helps.
For any US point PinPoint Treasure reports the land manager and what is and is not allowed there before it recommends fieldwork. Ask PinPoint Treasure about a specific place or story and it researches the records for you: newspapers, land and mining records, old maps, LiDAR and land status, with the source behind every claim.
Is metal detecting legal on BLM land? Casual metal detecting is generally allowed on much Bureau of Land Management land, but removing archaeological resources over 100 years old is illegal without a permit, and some areas are closed. Check the specific location.
Who owns treasure found on private land? Generally the landowner, subject to state law. Always get written permission and agree on finds before you search.
