Intermountain Natural History Association is a private, not-for-profit 501(c)(3) organization created to aid the educational and scientific activities of the National Park Service at Dinosaur and Fossil Butte national monuments, the U.S. Forest Service at the Ashley, Uinta-Wasatch-Cache national forests and the Bureau of Land Management at the John Jarvie Historic Property in Browns Park. The profits from all bookstore sales are donated back to these public lands. Since INHA's inception in 1956, donations have exceeded $2.5 million.

Donations are given to the agencies to support specific activities or projects. These can include production and printing of newspapers, construction of information kiosks, or the financing of roadside displays, trail guides, and handouts. INHA donations help to purchase items as large as the cast skeleton of Allosaurus at Dinosaur, and as small as a roll of film for documenting projects.

Our organization was founded in 1956 as the Dinosaur Nature Association. In 1999, we expanded beyond our relationship with the National Park Service to begin serving the USDA Forest Service and the BLM. To better reflect these relationships, in 2002 we officially became Intermountain Natural History Association.
