Waterproof, Tear-Resistant Travel Map. National Geographic's Destination Map of National Parks of the United States highlights the nearly 400 magnificent parks across America. The country is represented in subtle earth-tones with shaded mountain relief and intricately drawn river systems. Photos capture some of the diverse landscapes preserved and protected by the national park system. A list of all park service units, sorted by state, is also included to help you find the closest park, national monument, or national historic site. Every Destination Map is printed on durable synthetic paper, making them waterproof, tear-resistant and tough - capable of withstanding the rigours of any kind of travel.
