As one of the oldest nonprofits in the region, 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, sharing with the public the importance of the Sierra public lands. 50 years later EISA continues to strive to educate, inspire, and explore!
