The Theodore Roosevelt Nature & History Association, established in 1951, aids and promotes the historical, scientific and educational activities of the National Park Service.  We have expanded that support to include the United States Fish and Wildlife Service. TRNHA is an education institution that functions as a part of the interpretive arm of the national park system and wildlife refuges. 

A not-for-profit cooperating association chartered by Congress, TRNHA is a business that acquires or produces and sells cultural materials to enhance the enjoyment of visitors at Theodore Roosevelt National Park, Knife River Indian Villages National Historic Site, and Upper Souris National Wildlife Refuge
