Ken Burns: The National Parks - America's Best Idea (Blu-ray)

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.
