The National Park System
The National Park System of the United States is administered by the National Park Service, a bureau of the Department of the Interior. Started with the establishment of Yellowstone National Park on March 1, 1872, the system includes not only the most extraordinary and spectacular scenic exhibits in the United States, but also a large number of sites distinguished for their historic or prehistoric importance, scientific interest, or superior recreational assets. The National Park System is made up of 388 areas covering more than 84 million acres in every state except Delaware. It also includes areas in the District of Columbia, American Samoa, Guam, Puerto Rico, and the Virgin Islands. A list of the areas follows, excluding those without ?national? status.
