Cooperating Association
|
Western National Parks Association (WNPA) 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. Today WNPA operates bookstores at sixty-five National Park Service sites throughout the western United States and proceeds from the sales are returned to the National Park Service to aid the educational and interpretive activities in the parks. |
