Western National Parks Association is a nonprofit cooperating association of the National Park Service. Headquartered in Tucson, Arizona, the association was founded in 1938 as the Southwest Monuments Association to support the interpretive activities of the National Park Service. Sunrise at Saguaro National Park, Tucson, Arizona. Today we operate bookstores at sixty-six National Park Service sites throughout the western United States, plus an online store with more than 600 educational products. In addition to developing publications, Western National Parks Association supports park research and helps fund programs that make park visits more meaningful. One of our founding goals was to create and publish park-related information unavailable elsewhere. Currently we have more than 175 books in print with many new publications introduced yearly. Western National Parks Association supports parks by producing more than a half million pieces of free literature annually, including trail guides, newspapers, schedules, and brochures. Since our 1938 founding, we've contributed more than $55 million to national parks, generated through store sales to park visitors and the support of our members.
