Book excerpt: The flagship publication of the National Parks Conservation Association, National Parks Magazine (circ. 340,000) fosters an appreciation of the natural and historic treasures found in the national parks, educates readers about the need to preserve those resources, and illustrates how member contributions drive our organization's park-protection efforts. National Parks Magazine uses images and language to convey our country's history and natural landscapes from Acadia to Zion, from Denali to the Everglades, and the 387 other park units in between.
