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.

On December 17, 1903, at Kitty Hawk, North Carolina, Wilbur and Orville Wright's Wright Flyer became the first powered, heavier-than-air machine to achieve controlled, sustained flight with a pilot aboard. The Age of Flight had begun. How did they do it? And why?

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.

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.

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.

At once an incredible adventure narrative and a penetrating biographical portrait, Egan's book tells the remarkable untold story behind Edward Curtis's iconic photographs, following him throughout Indian country from desert to rainforest as he struggled to document the stories and rituals of more than eighty tribes.

When a shattered kayak and camping gear are found on an uninhabited island, they reignite a mystery surrounding a shocking act of protest. Five months earlier, logger-turned-activist Grant Hadwin had plunged naked into a river in British Columbia's Queen Charlotte Islands, towing a chainsaw. 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.

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.

The legendary annihilation in 1883 of the volcano-island of Krakatoa - the name has since become a byword for a cataclysmic disaster - was followed by an immense tsunami that killed nearly 40,000 people. Beyond the purely physical horrors of an event that has only very recently been properly understood, the eruption changed the world in more ways than could possibly be imagined. Dust swirled round die planet for years, causing temperatures to plummet and sunsets to turn vivid with lurid and unsettling displays of light.

The Smoky God is a classic tale from the genre of hollow Earth or subterranean literature.

While in the center of the Earth, they find an entire society and meet a race and of advanced giants.

In 1839 rumors of extraordinary yet baffling stone ruins buried within the unmapped jungles of Central America reached two of the world's most intrepid travelers. Seized by the reports, American diplomat John Lloyd Stephens and British artist Frederick Catherwood sailed together out of New York Harbor on an expedition into the forbidding rainforests of present-day Honduras, Guatemala, and Mexico. What they found would rewrite the West's understanding of human history.

I hate every wave of the ocean', the seasick Charles Darwin wrote to his family during his five-year voyage on the H.M.S. Beagle. It was this world-wide journey, however, that launched the scientists career.

Henry David Thoreau has long been an intellectual icon and folk hero. In this strikingly original profile, Michael Sims reveals how the bookish, quirky young man evolved into the patron saint of environmentalism and nonviolent activism. Working from 19th-century letters and diaries, Sims charts Henry’s course from his time at Harvard through the years he spent living in a cabin beside Walden Pond. Sims uncovers a previously hidden Thoreau - the rowdy boy reminiscent of Tom Sawyer, the sarcastic college iconoclast, the devoted son who kept imitating his beloved older brother’s choices in life.

On June 6, 1761, the world paused to observe a momentous occasion: the first transit of Venus between the earth and the sun in more than a century. Through that observation, astronomers could calculate the size of the solar system - but only if they could compile data from many different points of the globe, all recorded during the short period of the transit. Fortunately, transits of Venus occur in pairs: eight years later, the scientists would have another opportunity to succeed.

Aside from love, few actvities seem to promise us as much happiness as going traveling: taking off for somewhere else, somewhere far from home, a place with more interesting weather, customs, and landscapes. But although we are inundated with advice on where to travel, few people seem to talk about why we should go and how we can become more fulfilled by doing so.

Falling Upwards tells the story of the enigmatic group of men and women who first risked their lives to take to the air and so discovered a new dimension of human experience. Why they did it, what their contemporaries thought of them, and how their flights revealed the secrets of our planet in wholly unexpected ways is its subject.

Lewis and his partner, Captain William Clark, endured incredible hardships and witnessed astounding sights. With great perseverance, they worked their way into an unexplored West. When they returned two years later, they had long since been given up for dead.

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.
