[Editor's note: Thanks to Tom's efforts, we continue to expand Natural Earth coverage this week by adding U.S. National Parks to the 1:10,000,000 scale set. Do you have a few hours to spare? We'd like to add National Forests, large state parks, and wilderness areas to our Parks and Protected Areas theme.]

Includes the 392 authorized National Park Service units in the United States of America. The data does not include affiliated areas and unauthorized park units. Park units over 100,000 acres (~40,000 hectares) appear as areas, park units under 100,000 acres as points, and linear parks, including rivers, trails, and seashores, as lines. There are a few exceptions to this rule.
Many parks are comprised of scattered, non-contiguous land parcels. Not all of these are shown, especially in urban areas and the northeastern US. Dots generally indicate the center of the largest parcel or the parcel where the visitor center is located.
(above) Units in the southern United States include Great Smoky Mountains National Park, the Appalachian National Scenic Trail, Stones River National Battlefield, Andrew Johnson National Historic Park, the Obed Wild and Scenic River, and Big South Fork National River and Recreation Area.
