In partnership with the U.S. Forest Service, U.S. National Park Service, and the Bureau of Land Management, the Eastern Sierra Interpretive Association (ESIA) is dedicated to forging strong emotional and intellectual bonds between the Sierra Nevada and the visitors and residents of this broad region. Our work helps people deepen their relationship with this special place and develop a commitment to protecting it. 

Your contribution allows ESIA to provide critical interpretive programs to educate and inspire people to become stewards of the land and care for this special region.

As a token of our thanks, you will receive a discount on our retail items (both in our bookstores and online) and events, receive an ESIA Member gift (tote bag, water bottle, or artisan mug), and join our email list to keep you informed about all of our exciting projects as well as our quarterly newsletter.

Donations in smaller amounts are also greatly appreciated and will be put to good use.

Custom donation amounts are accepted and your membership perks will be described by the categories below.
