As of February 22, 2010, a new federal law allows people who can legally possess firearms under applicable federal, state, and local laws, to legally possess firearms on lands owned by the National Park Service.
Lands along the Lewis and Clark National Historic Trail are owned by many entities. The Lewis and Clark National Historic Trail traverses eleven states and numerous Indian lands. It is the responsibility of visitors to understand and comply with all applicable state, local, tribal and federal firearms laws before traveling the Lewis and Clark National Historic Trail.
Federal law also prohibits firearms in certain facilities along the Lewis and Clark National Historic Trail. These places are marked with signs at all public entrances.
