Traces the birth of the national park idea in the mid-1800s and follows its evolution for nearly 150 years. Using archival photographs, first-person accounts of historical characters, personal memories and analysis from more than 40 interviews, and what Burns believes is the most stunning cinematography in Florentine Films' history, the series chronicles the steady addition of new parks through the stories of the people who helped create them and save them from destruction.
