Supporting North Dakota's National Parks Since 1951!

TRNHA, a nonprofit organization, exists to assist and support Theodore Roosevelt National Park, Knife River Indian Villages National Historic Site, and Upper Souris National Wildlife Refuge. Proceeds from our retail operations, memberships, and donations support the educational, interpretive, and scientific research programs to enhance the experience of park visitors.

We have 3 bookstores in Theodore Roosevelt National Park in remote western North Dakota.
