THE NATIONAL PARKS is the story of an idea as uniquely American as the Declaration of Independence: that the most special places in the nation should be preserved for everyone. The series traces the birth of the national park idea in the mid-1800s and follows its evolution for nearly 150 years, chronicling the addition of new parks through the stories of the people who helped create them.
The National Parks: America's Best Idea by Ken Burns. This film series first aired on PBS in October, 2010 and is fantastic both in history and videography. DVD and Soundtrack are stunning. Can buy on PBS or Amazon.
