Zion Natural History Association The Zion Natural History Association ( ZNHA ) is a non-profit organization established in 1929 to support education, research, publication and other programs for the benefit of Zion National Park, Cedar Breaks National Monument, and Pipe Spring National Monument. Financial support by ZNHA members combines with the sales from our bookstores to provide the parks with approximately $600, 000 in aid annually. The educational arm of ZNHA is the Zion Canyon Field Institute ( ZCFI ) which provides dozens of hands-on one- to three-day seminars each year. Your membership in ZNHA not only sustains the programs listed above, but also helps finance the free Junior Ranger Programs for children, and publications such as the "Zion Map and Guide" received upon entrance to Zion National Park.
