The story of the world's largest, longest, and best-financed scientific expedition of all time, triumphantly successful, gruesomely tragic, and never before fully told. The immense 18th-century scientific journey, variously known as the Second Kamchatka Expedition or the Great Northern Expedition, from St. Petersburg across Siberia to the coast of North America, involved over 3,000 people and cost Peter the Great over one-sixth of his empire's annual revenue.

For the last 50 years, the trees of the boreal forest have been moving north. The Treeline takes us along this critical frontier of our warming planet from Norway to Siberia, Alaska to Greenland, to meet the scientists, residents, and trees confronting huge geological changes.

For decades, Dick Conant paddled the rivers of America, covering the Mississippi, Yellowstone, Ohio, Hudson, as well as innumerable smaller tributaries. These solo excursions were epic feats of planning, perseverance, and physical courage. At the same time, Conant collected people wherever he went, creating a vast network of friends and acquaintances who would forever remember this brilliant and charming man even after a single meeting.

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.

In the summer of 1913, the wooden-hulled brigantine Karluk departed Canada for the Arctic Ocean. At the helm was Captain Bob Bartlett, considered the world’s greatest living ice navigator. The expedition’s visionary leader was a flamboyant impresario named Vilhjalmur Stefansson hungry for fame. Just six weeks after the Karluk departed, giant ice floes closed in around her. As the ship became icebound, Stefansson disembarked with five companions and struck out on what he claimed was a 10-day caribou hunting trip. Most on board would never see him again.

Traveling along the Yukon as the salmon migrate, a four-month journey through untrammeled landscape, Adam Weymouth traces the fundamental interconnectedness of people and fish through searing and unforgettable portraits of the individuals he encounters. He offers a powerful, nuanced glimpse into indigenous cultures and into our ever-complicated relationship with the natural world.

In 1541, the brutal conquistador Gonzalo Pizarro and his well-born lieutenant Francisco Orellana set off from Quito in search of La Canela, South America's rumored Land of Cinnamon, and the fabled El Dorado, "the golden man". Driving an enormous retinue of mercenaries, enslaved natives, horses, hunting dogs, and other animals across the Andes, they watched their proud expedition begin to disintegrate even before they descended into the nightmarish jungle, following the course of a powerful river.

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.

What causes people to forsake their country and take arms against it? What prompts their neighbors, hardly distinguishable in station or success, to defend that country against the rebels?  That is the question H. W. Brands answers in his powerful new history of the American Revolution.

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.

In 1899, railroad magnate Edward H. Harriman organized a most unusual summer voyage to the wilds of Alaska: He converted a steamship into a luxury "floating university", populated by some of America's best and brightest scientists and writers, including the anti-capitalist eco-prophet, John Muir. Armed with Dramamine and an industrial-strength mosquito net, Mark Adams sets out to retrace the 1899 expedition. Using the state's intricate public ferry system, the Alaska Marine Highway System, Adams travels 3,000 miles.

Deep in the Arctic wilderness, Peter Freuchen awoke to find himself buried alive under the snow. During a sudden blizzard the night before, he had taken shelter underneath his dogsled and become trapped there while he slept. Now, as feeling drained from his body, he managed to claw a hole through the ice only to find himself in even greater danger: his beard, wet with condensation from his struggling breath, had frozen to his sled runners and lashed his head in place, exposing it to icy winds that needed only a few minutes to kill him. If Freuchen could escape that, he could escape anything.

In 1930, two novice paddlers - Eric Sevareid and Walter C. Port - launched a secondhand 18-foot canvas canoe from the Minnesota River at Fort Snelling for an ambitious summer-long journey from Minneapolis to Hudson Bay. Without benefit of radio, motor or good maps, the teenagers made their way over 2,250 miles of rivers, lakes, and difficult portages.

Even among iconic frontiersmen like John C. Fremont, Kit Carson, and Jedediah Smith, Jim Bridger stands out. A mountain man of the American West, straddling the fur trade era and the age of exploration, he lived the life legends are made of. Here, in a biography that finally gives this outsize character his due, Jerry Enzler takes this frontiersman's full measure for the first time—and tells a story that would do Jim Bridger proud.

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.
