Theodore Roosevelt Nature and History Association

Supporting North Dakota's Public Lands Since 1951!

Supporting Our Park Partners

TRNHA works hard to support our partners and we couldn't do it without the support of our members and friends. In 2017, we were honored to receive several donations to help us host and support events within the parks we serve.


Donations in 2017 were used to host our Teddy Bear Picnics and assist with the Dakota Nights Astronomy Festival in Theodore Roosevelt National Park. We also used these funds to provide support to Knife River Indian Villages NHS annual Lifeways of the Northern Plains Event.
