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 10 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.

The Colorado River is an essential resource for a surprisingly large part of the United States, and every gallon that flows down it is owned or claimed by someone. David Owen traces all that water from the Colorado’s headwaters to its parched terminus, once a verdant wetland but now a million-acre desert. He takes listeners on an adventure downriver, along a labyrinth of waterways, reservoirs, power plants, farms, fracking sites, ghost towns, and RV parks, to the spot near the US-Mexico border where the river runs dry.

The Last River: The Tragic Race for Shangri-la is a breathtaking account of the ill-fated October 1998 expedition of an American whitewater kayaking team who traveled deep into the Tsangpo Gorge in Tibet to run the Yarlung Tsangpo, known in paddling circles as the "Everest of rivers." For Wick Walker and Tom McEwan, extreme whitewater pioneers, best friends, and trip leaders, the Tsangpo adventure was the culmination of a twenty-five-year quest for glory. Yet the team's magnificent dreams crumbled when their ace paddler was swept over a thunderous eight-foot waterfall, never to be seen again.

In the summer of 1938, botanists Elzada Clover and Lois Jotter set off to run the Colorado River, accompanied by an ambitious and entrepreneurial expedition leader, a zoologist, and two amateur boatmen. With its churning waters and treacherous boulders, the Colorado was famed as the most dangerous river in the world. Journalists and veteran river runners boldly proclaimed that the motley crew would never make it out alive. But for Clover and Jotter, the expedition held a tantalizing appeal: no one had yet surveyed the plant life of the Grand Canyon, and they were determined to be the first.

As a park ranger with the National Park Service's law enforcement team, Andrea Lankford led search and rescue missions in some of the most beautiful (and dangerous) landscapes across America, from Yosemite to the Grand Canyon. But though she had the support of the agency, Andrea grew frustrated with the service's bureaucratic idiosyncrasies, and left the force after twelve years. Two decades later, however, she stumbles across a mystery that pulls her right back where she left off: three young men have vanished from the Pacific Crest Trail.

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.

Thus began one of history's dramatic but largely forgotten turning points in the conquest of the North American continent.
