Knopf 2009 America’s national parks spring from an idea as radical as the Declaration of Independence: that the nation’s most magnificent and sacred places should be preserved, not for royalty or the rich, but for everyone. In this evocative and lavishly illustrated narrative, Ken Burns and Dayton Duncan delve into the history of the park idea, from the first sighting by white men in 1851 of the valley that would become Yosemite and the creation of the world’s first national park at Yellowstone in 1872, through the most recent additions to a system that now encompasses nearly four hundred sites and 84 million acres.
