Glen Canyon Natural History Association. We are a non-profit organization dedicated to education, interpretation, and research within Glen Canyon National Recreation Area, Rainbow Bridge National Monument, Glen Canyon Dam, Grand Staircase-Escalante National Monument, and other federal lands.

Glen Canyon Natural History Association was created in 1986, and provides aid to the National Park Service and the Bureau of Land Management through sales of educational materials at interpretive bookstores, and to the Bureau of Reclamation by managing the tours of Glen Canyon Dam.
