Welcome to the Craters of the Moon Natural History Association. We are a private nonprofit organization established in 1959. Our mission is to asist our National Park Service partners with interpretive, educational, and scientific activities at Craters of the Moon National Monument, Hagerman Fossil Beds National Monument, and Minidoka National Historic Site. Through the operation of two retail stores, an online store, and membership dues, the NHA provides much needed funds for these activities.
