Our national parks

"For every person who has experienced the beauty of the mountains and felt humbled by comparison . . . Take in John Muir's detailed observations of the sights, scents, sounds, and textures of Yosemite, Yellowstone, and forest reservations of the West. Be reminded (as Muir sagely puts), 'Wildness is a necessity; and that mountain parks and reservations are useful not only as fountains of timber and irrigating rivers, but as fountains of life.'"--Publisher.
