The Death Valley Natural History Association (DVNHA) is a non-profit organization dedicated to providing quality educational products to the public and services to Death Valley National Park. DVNHA functions as: a part of the interpretive arm of the National Park Service, a business that acquires or produces and sells materials to enhance the enjoyment of park visitors, and a philanthropic organization that disperses its net income to the National Park Service for its diverse programs. The DVNHA operates sales outlets at the Furnace Creek Visitor Center, the Stovepipe Wells Ranger Station, Scotty's Castle Visitor Center and Museum, and the Beatty Information Station. The DVNHA Online Bookstore has just gone live and is available through the Association's website. The Natural History Association also conducts sales by telephone and by mail. All purchases benefit Death Valley National Park.
