In a lifetime of exploration, writing, and passionate political activism, John Muir made himself America's most eloquent spokesman for the mystery and majesty of the wilderness. A crucial figure in the creation of our national parks system and a visionary prophet of environmental awareness, he was also a master of natural description who evoked with unique power and intimacy the untrammeled landscapes of the American West. This book collects his most significant and best-loved works in a single volume.
