Full text of Powell's 1,000-mile expedition down the fabled Colorado in 1869. Superb account of terrain, geology, vegetation, Indians, famine, mutiny, treacherous rapids, mighty canyons. 240 illustrations.

One of the great works of American exploration literature, this account of a scientific expedition forced to survive famine, attacks, mutiny, and some of the most dangerous rapids known to man remains as fresh and exciting today as it was in 1874. The Exploration of the Colorado River and Its Canyons , recently ranked number four on Adventure magazine's list of top 100 classics, is legendary pioneer John Wesley Powell's first-person account of his crew's unprecedented odyssey along the Green and Colorado Rivers and through the Grand Canyon. A bold foray into the heart of the American West's final frontier, the expedition was achieved without benefit of modern river-running equipment, supplies, or a firm sense of the region's perilous topography and the attitudes of the native inhabitants towards whites.

John Wesley Powell was a pioneer American explorer, ethnologist, and geologist in the 19th Century. In 1869 he set out to explore the Colorado and the Grand Canyon. He gathered nine men, four boats and food for ten months and set out from Green River, Wyoming, on May 24. Passing through dangerous rapids, the group passed down the Green River to its confluence with the Colorado River (then also known as the Grand River upriver from the junction), near present-day Moab, Utah.

One hundred years ago John Wesley Powell set out to explore the Grand Canyon of the Colorado - something no man had attempted before. His official report of the voyage remains one of the great adventure stories in all the literature of the American West.

“A convincing case for Powell’s legacy as a pioneering conservationist.”--The Wall Street Journal "A bold study of an eco-visionary at a watershed moment in US history."--Nature A timely, thrilling account of the explorer who dared to lead the first successful expedition down the Colorado through the Grand Canyon—and waged a bitterly-contested campaign for sustainability in the West. 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. With The Promise of the Grand Canyon, John F. Ross tells how that perilous expedition launched the one-armed Civil War hero on the path to becoming the nation’s foremost proponent of environmental sustainability and a powerful, if controversial, visionary for the development of the American West. So much of what he preached—most broadly about land and water stewardship—remains prophetically to the point today.

Drawing on rarely examined diaries and journals, Down the Great Unknown is the first book to tell the full, dramatic story of the Powell expedition. On May 24, 1869 a one-armed Civil War veteran, John Wesley Powell and a ragtag band of nine mountain men embarked on the last great quest in the American West. The Grand Canyon, not explored before, was as mysterious as Atlantis—and as perilous. The ten men set out from Green River Station, Wyoming Territory down the Colorado in four wooden rowboats. Ninety-nine days later, six half-starved wretches came ashore near Callville, Arizona. Lewis and Clark opened the West in 1803, six decades later Powell and his scruffy band aimed to resolve the West’s last mystery. A brilliant narrative, a thrilling journey, a cast of memorable heroes—all these mark Down the Great Unknown, the true story of the last epic adventure on American soil.
