During John Muir's extraordinary life as a conservationist, he traveled through most of the American wilderness alone and on foot, without a gun or a sleeping bag. In 1903, while on a three-day camping trip with President Theodore Roosevelt, he convinced the president of the importance of a national conservation program, and he is given major credit for saving the Grand Canyon and Arizona's Petrified Forest. Muir's writing, based on journals he kept throughout his life, gives our generation a picture of an America still wild and unsettled only one hundred years ago. Edwin Way Teale has collected here the best of Muir's writing, selected from all of his major works, including MY FIRST SUMMER IN THE SIERRA and TRAVELS IN ALASKA. THE WILDERNESS WORLD OF JOHN MUIR provides "reading that is often magnificent, thrilling, exciting, breathtaking, and awe-inspiring" (Kirkus Reviews).
