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.

Since its inception, however, America’s public land system has been embroiled in controversy - caught in the push and pull between the desire to develop the valuable resources the land holds or conserve them. Alarmed by rising tensions over the use of these lands, hunter, angler, and outdoor enthusiast Mark Kenyon set out to explore the spaces involved in this heated debate, and learn firsthand how they came to be and what their future might hold.

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.

On a mountain somewhere above treeline, in some of the coldest and worst winter conditions imaginable, two men lie unconscious in the snow as explosive winds batter the nearby summits. In The Last Traverse: Tragedy and Resilience in the Winter Whites, Ty Gagne masterfully lays out the events that led up to an epic and legendary rescue attempt in severe and dangerous winter conditions in the White Mountains of New Hampshire. More than a cautionary tale, it is a tribute to all the volunteers and professionals who willingly put themselves in harm's way to save lives.

From one of our most acclaimed and original colonial historians, a groundbreaking book - the first to look at the critical "long year" of 1774 and the revolutionary change that took place from December 1773 to mid-April 1775, from the Boston Tea Party and the First Continental Congress to the Battles of Lexington and Concord.

His destination was the uncharted end of the earth: the icy continent of Antarctica. But de Gerlache’s plans to be first to the magnetic South Pole would swiftly go awry. After a series of costly setbacks, the commandant faced two bad options: turn back in defeat and spare his men the devastating Antarctic winter, or recklessly chase fame by sailing deeper into the freezing waters.

At the dawn of the 20th century, when human flight was still considered an impossibility, Germany’s Count Ferdinand von Zeppelin vied with the Wright Brothers to build the world’s first successful flying machine. As the Wrights labored to invent the airplane, Zeppelin fathered the remarkable airship, sparking a bitter rivalry between the two types of aircraft and their innovators that would last for decades, in the quest to control one of humanity’s most inspiring achievements. And it was the airship—not the airplane—that led the way.

In The Ice at the End of the World, Jon Gertner explains how Greenland has evolved from one of earth’s last frontiers to its largest scientific laboratory. The history of Greenland’s ice begins with the explorers who arrived here at the turn of the 20th century. Their original goal was to conquer Greenland’s seemingly infinite interior. Yet their efforts eventually gave way to scientists who built lonely encampments out on the ice and began drilling - one mile, two miles down.Their aim was to pull up ice cores that could reveal the deepest mysteries of earth’s past.

The history of Iceland began 1,200 years ago, when a frustrated Viking captain and his useless navigator ran aground in the middle of the North Atlantic.

This kaleidoscopic book covers almost 3,000 years of Arab history and shines a light on the footloose Arab peoples and tribes who conquered lands and disseminated their language and culture over vast distances. Tracing this process to the origins of the Arabic language, rather than the advent of Islam, Tim Mackintosh-Smith begins his narrative more than a thousand years before Muhammad and focuses on how Arabic, both spoken and written, has functioned as a vital source of shared cultural identity over the millennia.

When Conor Knighton set off to explore America's "best idea", he worried the whole thing could end up being his worst idea. A broken engagement and a broken heart had left him longing for a change of scenery, but the plan he'd cooked up in response had gone a bit overboard in that department: Over the course of a single year, Knighton would visit every national park in the country, from Acadia to Zion.

“As Albert Einstein almost certainly never said, everyone is a genius—but if you judge a fish by its ability to climb a tree, it will live its whole life believing that it is stupid.” So begins Katie Spalding’s spunky takedown of the Western canon, and how genius may not be as irrefutably great as we commonly understand. While most of us may never become Einstein, it may surprise you to learn that there’s probably a bunch of stuff you can do that Einstein couldn’t. And, as Spalding shows, the famous prodigies she explores here were quite odd by any definition.

With rare detail and in consummate style, Steve Inskeep tells the story of a couple whose joint ambitions and talents intertwined with those of the nascent United States itself.

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.

Standing on the Rim, surrounded by the profound and almost mystical silence, Fletcher knew that something had happened to the way he looked at things.
