Grand Teton Natural History Association (GTNHA) was founded in 1937 as a Cooperating Association to provide informational materials to be sold to park visitors. All sales items are approved by the Park Service and must serve educational and interpretive functions. Under this continued authority, space is provided in National Park Service buildings.

When you make a purchase from our park bookstores, you are supporting the educational, interpretive, and scientific programs in Grand Teton National Park. All profits from your purchases are used to finance new publications and to assist the National Park Service to lead visitors not only to admire but to better understand our parks.

Annual memberships in GTNHA are available. Members receive a 15% discount on all purchases through GTNHA and in Cooperating Association Bookstores in most national parks.
