"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.

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.

His second major venture into nonfiction (after Death in the Afternoon, 1932), Green Hills of Africa is Ernest Hemingway's lyrical journal of a month on safari in the great game country of East Africa, where he and his wife, Pauline, journeyed in December of 1933. Hemingway's well-known interest in - and fascination with - big-game hunting is magnificently captured in this evocative account of his trip.

For two years, Scots-born John Muir lived in a small cabin along the Yosemite creek, observing the valley's natural beauty and reading Emerson under the stars. The experience forged a lifelong affinity with the site, which would result in its establishment as a national park in 1890. Originally written as a guidebook to the park, The Yosemite describes every aspect of wildlife and landscape that one might encounter there.

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.

The best-selling author of Truman and John Adams, David McCullough has written profiles of exceptional men and women past and present who have not only shaped the course of history or changed how we see the world but whose stories express much that is timeless about the human condition. Here are Alexander von Humboldt, whose epic explorations of South America surpassed the Lewis and Clark expedition; Harriet Beecher Stowe, "the little woman who made the big war”....

How did America become “one nation, indivisible”? What unified a growing number of disparate states into the modern country we recognize today? To answer these questions, Winchester follows in the footsteps of America’s most essential explorers, thinkers, and innovators. Introducing the fascinating people who played a pivotal role in creating today’s United States, he ponders whether the historic work of uniting the States has succeeded, and to what degree.

Thomas Edison was born into a hard-working but attentive family. He struggled in school and became deaf at an early age. Born on February 11, 1847, Edison would become, arguably, the best-known American inventor of all time. His invention of the light bulb was one of more than 1,000 patents he held during his lifetime. Others included the phonograph, the electrical grid, and motion pictures. His work changed the way we see and hear the world around us.

In a landmark work of history, Russell Shorto presents astonishing information on the founding of our nation and reveals in riveting detail the crucial role of the Dutch in making America what it is today.

Frederick Law Olmsted is arguably the most important historical figure that the average American knows the least about. Best remembered for his landscape architecture, from New York's Central Park to Boston's Emerald Necklace to Stanford University's campus, Olmsted was also an influential journalist, early voice for the environment, and abolitionist credited with helping dissuade England from joining the South in the Civil War. This momentous career was shadowed by a tragic personal life, also fully portrayed here.

Pulitzer Prize winner Wallace Stegner recounts the remarkable career of Major John Wesley Powell, the distinguished ethnologist and geologist who explored the Colorado River, the Grand Canyon, and the homeland of the Southwest Indian tribes. This classic work is a penetrating and insightful study of the Powell’s career, from the beginning of the Powell Survey, in which Powell and his men famously became the first to descend the Colorado River, to his eventual expulsion from the Geological Survey.

John Wesley Powell’s first descent of the Colorado River through the Grand Canyon in 1869 counts among the most dramatic chapters in American exploration history. When the Canyon spit out the surviving members of the expedition - starving, battered, and nearly naked - they had accomplished what others thought impossible and finished the exploration of continental America that Lewis and Clark had begun almost 70 years before.

Meriwether Lewis discovered far more than the history books tell - ancient civilizations, strange monuments, "nearly white, blue-eyed" Indians, and evidence that the American continent was visited long before the first European settlers arrived. And he was murdered to keep it all secret. Examining the shadows and cracks between America's official version of history, Xaviant Haze and Paul Schrag propose that the America of old taught in schools is not the America that was discovered by Lewis and Clark and other early explorers.

The career of John Charles Frémont (1813-90) ties together the full breadth of American expansionism from its 18th-century origins through its culmination in the Gilded Age. Tom Chaffin's biography demonstrates Frémont's vital importance to the history of American empire and illuminates his role in shattering long-held myths about the ecology and habitability of the American West.
