How to Stay Legal: - Don't dig on federal land without understanding rules - If you find something historic, report it - Get permits when required - Stick to modern-loss areas
Always: - Get written permission on private land - Know the rules before you hunt - Fill all holes completely - Remove all trash found - Report significant finds
Never: - Trespass for any reason - Dig on protected sites - Remove artifacts from federal land - Hunt posted private property
When in Doubt: Call ahead. Land managers, park rangers, and local clubs can clarify rules.
