The NNational Park System encompasses 417 national parks in the United States. They span across more than 84 million acres in each state and extend into the territories, including parks in Puerto Rico, the Virgin Islands, American Samoa, and Guam.

Americans wanted to visit these places to experience their beauty firsthand, whether they traveled by train, steamship, or, increasingly, by automobile. - Devereux Butcher
