As one of the region's oldest nonprofits, the Eastern Sierra Interpretive Association (ESIA) was established in 1970 by visionary citizens interested in helping the U.S. Forest Service provide interpretive education relevant to the unique surrounding landscape. Upon receiving its nonprofit 501(c)3 status in 1971, ESIA became one of the first independent organizations in the United States to operate under a Participating Agreement with the U.S. Forest Service for educational purposes. Today, ESIA's ongoing agency partnerships include the Inyo National Forest, Humboldt-Toiyabe National Forest, Tahoe National Forest, Devils Postpile National Monument, Manzanar National Historic Site and the Bureau of Land Management Bishop Field Office. 

ESIA along with our public land agency partners operate successful visitor centers, and provide high quality interpretive programs and exhibits. Through sale of interpretive products and philanthropic contributions. Learn more >>
