As of February 22, 2010, a new federal law allows individuals who can legally possess firearms under applicable federal, state, and local laws, to legally possess firearms in many National Park units.
Navajo National Monument is located within the exterior boundaries of the Navajo Nation. Subject to certain exceptions, Navajo Nation Code, tit. 17, § 320 (1979), provides that “[a] person commits unlawful carrying of a deadly weapon if he or she carries a loaded firearm or any other type of deadly weapon.” The Navajo Nation may enforce its laws against Navajos and may charge non-Navajos with civil violations under this and other provisions of the Navajo Nation Code. Non-Navajos may be escorted off or totally banned from the reservation. It is the responsibility of visitors to understand and comply with all applicable tribal, state, and federal firearms laws before entering this park.
Federal law still prohibits firearms in certain facilities in this park; those places are marked with signs at all public entrances and includes the Visitor Center, Ranger office, and Maintenance building.
