The pioneering advocate of wilderness preservation, John Muir (1838-1914) was influential in the creation of many national parks.

Part of John Muir's appeal to modern audiences is that he not only explored the American West and wrote about its beauties but also fought for their preservation. His successes dot the landscape and are evident in all the natural features that bear his name: forests, lakes, trails, and glaciers. Here collected are some of Muir's finest wilderness essays, ranging in subject matter from Alaska to Yellowstone, from Oregon to the High Sierra.

In the summer of 1869, John Muir, a young Scottish immigrant, joined a crew of shepherds in the foothills of California's Sierra Nevada Mountains. The diary he kept while tending sheep formed the heart of this book, which was first published in 1911 and which eventually lured thousands of Americans to visit Yosemite country. My First Summer in the Sierra incorporates the lyrical accounts and sketches Muir produced during his four-month stay in the Yosemite River Valley and the High Sierra.

Alexander von Humboldt (1769-1859) was an intrepid explorer and the most famous scientist of his age. His restless life was packed with adventure and discovery, whether climbing the highest volcanoes in the world or racing through anthrax-infested Siberia. He came up with a radical vision of nature, that it was a complex and interconnected global force and did not exist for man's use alone. Ironically, his ideas have become so accepted and widespread that he has been nearly forgotten.

In 1793 William Smith, a canal digger, made a startling discovery that was to turn the fledgling science of the history of the earth - and a central plank of established Christian religion - on its head. He noticed that the rocks he was excavating were arranged in layers; more important, he could see quite clearly that the fossils found in one layer were very different from those found in another. And out of that realization came an epiphany.

When his night's work was done, a unique Sitka spruce, 165 feet tall and covered with luminous golden needles, teetered on its stump. Two days later it fell.

"I am hopelessly and forever a mountaineer," John Muir wrote. "Civilization and fever and all the morbidness that has been hooted at me has not dimmed my glacial eye, and I care to live only to entice people to look at Nature's loveliness. My own special self is nothing". In Donald Worster's magisterial biography, John Muir's "special self" is fully explored as is his extraordinary ability, then and now, to get others to see the sacred beauty of the natural world.
