Examines the beginning of the American conservation movement and the impact of the idea of wilderness on American society and culture. Chronicles the lives of John Muir and Gifford Pinchot, including their opposition over the use of the Hetch Hetchy valley in Yosemite National Park.
"En 1913, le projet de faire un barrage dans le Yosemite National Park en Californie dans le but de subvenir aux besoins en eau de la ville de San Francisco, a soulevé la première contreverse environnementale aux Etats-Unis. Gifford Pinchat (chef des services forestiers) et John Muir (naturaliste et fondateur du Sierra Club) s'affrontent avec des visions différentes sur les méthodes de protections de l'environnement. Le gouvernement américain tranchera en faveur de la construction du barrage. Plusieurs extraits d'images de films d'archives et d'images du parc d'aujourd'hui sont présentées."

"Tells the story of the two founders of American conservation, John Muir and Gifford Pinchot, and their historic battle over whether a remote valley in California, Hetch Hetchy, should be dammed and flooded to form a reservoir. The battle reflected the two sides of the conservation issue--absolute protection of wilderness lands versus careful management and use of nature to serve human needs."@en
