At once an incredible adventure narrative and a penetrating biographical portrait, The River of Doubt is the true story of Theodore Roosevelt's harrowing exploration of one of the most dangerous rivers on earth.

In 1803, President Thomas Jefferson selected his personal secretary, Captain Meriwether Lewis, to lead a voyage up the Missouri River, across the forbidding Rockies, and - by way of the Snake and the Columbia rivers - down to the Pacific Ocean. 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.

The number one New York Times best seller by Pulitzer Prize-winning historian David McCullough rediscovers an important chapter in the American story that's "as resonant today as ever" (The Wall Street Journal) - the settling of the Northwest Territory by courageous pioneers who overcame incredible hardships to build a community based on ideals that would define our country.

The high points in the story of Alaska since the American acquisition are brought vividly to life through more than 100 characters, real and fictional.

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.

"Dr. Livingstone, I presume?" So goes the signature introduction of New York Herald star journalist Henry Morton Stanley to renowned explorer Dr. David Livingstone, who had been missing for six years in the wilds of Africa. Into Africa ushers us into the meeting of these remarkable men. In 1866, when Livingstone journeyed into the heart of the African continent in search of the Nile's source, the land was rough, unknown to Europeans, and inhabited by man-eating tribes.

For millennia the location of the Nile River’s headwaters was shrouded in mystery. In the 19th century, there was a frenzy of interest in ancient Egypt. At the same time, European powers sent off waves of explorations intended to map the unknown corners of the globe—and extend their colonial empires.

In the late nineteenth century, people were obsessed by one of the last unmapped areas of the globe: The North Pole. No one knew what existed beyond the fortress of ice rimming the northern oceans. On July 8, 1879, the USS Jeannette set sail from San Francisco to cheering crowds in the grip of "Arctic Fever." The ship sailed into uncharted seas, but soon was trapped in pack ice. Two years into the harrowing voyage, the hull was breached. Amid the rush of water and the shrieks of breaking wooden boards, the crew abandoned the ship.

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.

When gold was discovered at Sutter's Mill on the American River, it completely transformed the territory of California. Hundreds of thousands of people sped to California by any means possible, and small cities sprung up to service their needs as they sought the precious metal. By 1850, California had become a state; it had also become a symbol of where the nation was going.

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.

In late October 1846, the last wagon train of that year's westward migration stopped overnight before resuming its arduous climb over the Sierra Nevada Mountains, unaware that a fearsome storm was gathering force. After months of grueling travel, the 81 men, women and children would be trapped for a brutal winter with little food and only primitive shelter. The conclusion is known: by spring of the next year, the Donner Party was synonymous with the most harrowing extremes of human survival.

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.

Over a half century, Malibu went from an untamed ranch in the middle of nowhere to a paradise seeded with movie stars. Behind its transformation is the love story of Frederick and May Rindge. He was a Harvard-trained confidant of presidents; she grew up on a hardscrabble Midwestern farm; yet their unlikely bond would shape history.

A remarkable true story of adventure, betrayal, and survival set in one of the world's most inhospitable places. In 1906, from atop a snow-swept hill in the ice fields northwest of Greenland, hundreds of miles from another human being, Commander Robert E. Peary spotted a line of mysterious peaks looming in the distance. He called this unexplored realm "Crocker Land". Scientists and explorers agreed that the world-famous explorer had discovered a new continent rising from the frozen Arctic Ocean.

A riveting history of America's most beautiful natural resources, The Quiet World documents the heroic fight waged by the U.S. federal government from 1879 to 1960 to save wild Alaska - ;Mount McKinley, the Tongass and Chugach national forests, Gates of the Arctic, Glacier Bay, Lake Clark, and the Coastal Plain of the Beaufort Sea, among other treasured landscapes - from the extraction industries.

No American president has been more enthusiastic in appreciating the wilderness and in conserving our nation’s natural treasures than Theodore Roosevelt (1858-1919). And no other president wrote more about nature and his explorations of it than T. R., in scattered books, such as African Wilderness, and in his countless letters, including those collected in The Selected Letters of Theodore Roosevelt).

As 1909 dawned, the greatest jewels of exploration - set at the world's frozen extremes - lay unclaimed: the North and South Poles and the so-called "Third Pole", the pole of altitude, located in unexplored heights of the Himalaya. Before the calendar turned, three expeditions had faced death, mutiny, and the harshest conditions on the planet to plant flags at the furthest edges of the Earth.

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.

The Last Viking unravels the life of the man who stands head and shoulders above all those who raced to map the last corners of the world. In 1900, the four great geographical mysteries - the Northwest Passage, the Northeast Passage, the South Pole, and the North Pole - remained blank spots on the globe. Within twenty years Roald Amundsen would claim all four prizes.

The enthralling and often harrowing history of the adventurers who searched for the Northwest Passage, the holy grail of 19th-century British exploration. After the triumphant end of the Napoleonic Wars in 1815, the British took it upon themselves to complete something they had been trying to do since the 16th century: Find the fabled Northwest Passage, a shortcut to the Orient via a sea route over Northern Canada. For the next 35 years the British Admiralty sent out expedition after expedition to probe the ice-bound waters of the Canadian Arctic in search of a route.
