"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." . .

"In 1851, a band of Indian fighters in California encounters a place of astonishing beauty, setting in motion events that bring other newcomers to Yosemite Valley: artists, writers, entrepreneurs, tourists, and eventually John Muir, who becomes a national voice for preservation. Meanwhile, reports emerge from Wyoming Territory of a fantastical place at the headwaters of the Yellowstone River. An exploration confirms the rumors, and in 1872 Congress creates the world's first national park at Yellowstone, but does nothing to provide for its protection. In 1886, General Phil Sheridan and the U.S. Cavalry ride to the park's rescue."@en . . . . . "Television programs for the hearing impaired"@en . . "Nature television programs"@en .
