Keenly aware that the course of the nation's destiny lay westward—and that a "Voyage of Discovery" would be necessary to determine the nature of the frontier—President Thomas Jefferson commissioned Meriwether Lewis to lead an expedition from the Missouri River to the northern Pacific coast and back. From 1804 to 1806, accompanied by co-captain William Clark, the Shoshone guide Sacajawea, and thirty-two men, Lewis mapped rivers, traced the principal waterways to the sea, and established the American claim to the territories of Idaho, Washington, and Oregon. Together the captains kept this journal: a richly detailed record of the flora and fauna they sighted, the native tribes they encountered, and the awe-inspiring landscape they traversed, from their base camp near present-day St. Louis to the mouth of the Columbia River, that has become an incomparable contribution to the literature of exploration and the writing of natural history.

    Their initial optimism is short-lived, however, as the ice field slowly thickens, encasing the ship Endurance in a death-grip, crushing their craft, and marooning 28 men on a polar ice floe.In an epic struggle of man versus the elements, Shackleton leads his team on a harrowing quest for survival over some of the most unforgiving terrain in the world. Icy, tempestuous seas full of gargantuan waves, mountainous glaciers and icebergs, unending brutal cold, and ever-looming starvation are their mortal foes as Shackleton and his men struggle to stay alive.What happened to those brave men forever stands as a testament to their strength of will and the power of human endurance.This is their story, as told by the man who led them.

    Indeed, the expeditions of both Back (1837) and Ross (1849) were forced to retreat because of the rapacious illness that stalked their ships. The authors make the case that this illness was due to the crews’ overwhelming reliance on a new technology: tinned foods. This not only exposed the seamen to lead, an insidious poison, but also left them vulnerable to scurvy.The revised "Frozen in Time" will also update the research outlined in the original edition, and will introduce independent confirmation of Dr. Beattie’s lead hypothesis, along with corroboration of his discovery of physical evidence for both scurvy and cannibalism. In addition, the book includes a new introduction written by Margaret Atwood, who has long been fascinated by the role of the Franklin Expedition in Canada’s literary conscience.Includes never before seen photographs from the exhumations on Beechey Island and rarely seen historical illustrations.

    Gabrielle Walker, author, consultant to New Scientist and regular broadcaster with the BBC has written a book unlike any that has ever been written about the continent. Antarctica weaves all the significant threads into an intricate tapestry, made up of science, natural history, poetry, epic history, what it feels like to be there and why it draws so many different kinds of people back there again and again. It is only when all the parts come together that the underlying truths of the continent emerge. Antarctica is the most alien place on Earth, the only part of our planet where humans could never survive unaided. It is truly like walking on another planet. And yet, in its silence, its agelessness and its mysteries lie the secrets of our past, and of our future.

    The lifesaving serum was a thousand miles away, the port was icebound, and planes couldn't fly in blizzard conditions—only the dogs could make it. The heroic dash of dog teams across the Alaskan wilderness to Nome inspired the annual Iditarod Trail Sled Dog Race and immortalized Balto, the lead dog of the last team whose bronze statue still stands in New York City's Central Park. This is the greatest dog story, never fully told until now.

    Sir Douglas Mawson is remembered as the young Australian who would not go to the South Pole with Robert Scott in 1911, choosing instead to lead his own expedition on the less glamorous mission of charting nearly 1,500 miles of Antarctic coastline and claiming its resources for the British Crown. His party of three set out through the mountains across glaciers in 60-mile-per-hour winds. Six weeks and 320 miles out, one man fell into a crevasse, along with the tent, most of the equipment, all of the dogs' food, and all except a week's supply of the men's provisions.Mawson's Will is the unforgettable story of one man's ingenious practicality and unbreakable spirit and how he continued his meticulous scientific observations even in the face of death. When the expedition was over, Mawson had added more territory to the Antarctic map than anyone else of his time. Thanks to Bickel's moving account, Mawson can be remembered for the vision and dedication that make him one of the world's great explorers.

    For three men in particular, 1998 would become a grueling battle for a new North American birding record. Bouncing from coast to coast on frenetic pilgrimages for once-in-a-lifetime rarities, they brave broiling deserts, bug-infested swamps, and some of the lumpiest motel mattresses known to man. This unprecedented year of beat-the-clock adventures ultimately leads one man to a record so gigantic that it is unlikely ever to be bested. Here, prize-winning journalist Mark Obmascik creates a dazzling, fun narrative of the 275,000-mile odyssey of these three obsessives as they fight to win the greatest -- or maybe worst -- birding contest of all time.

    In this moving testimonial to the preservation of the Arctic wilderness, Mardy Murie writes from her heart about growing up in Fairbanks, becoming the first woman graduate of the University of Alaska, and marrying noted biologist Olaus J. Murie. So begins her lifelong journey in Alaska and on to Jackson Hole, Wyoming where along with her husband and others, they founded The Wilderness Society. Mardy's work as one of the earliest female voices for the wilderness movement earned her the Presidential Medal of Freedom.

    Alexander von Humboldt (1769 – 1859) was an intrepid explorer and the most famous scientist of his age. In North America, his name still graces four counties, thirteen towns, a river, parks, bays, lakes, and mountains. His restless life was packed with adventure and discovery, whether he was climbing the highest volcanoes in the world or racing through anthrax-infected Siberia or translating his research into bestselling publications that changed science and thinking. Among Humboldt's most revolutionary ideas was a radical vision of nature, that it is a complex and interconnected global force that does not exist for the use of humankind alone. Now Andrea Wulf brings the man and his achievements back into focus: his daring expeditions and investigation of wild environments around the world and his discoveries of similarities between climate and vegetation zones on different continents. She also discusses his prediction of human-induced climate change, his remarkable ability to fashion poetic narrative out of scientific observation, and his relationships with iconic figures such as Simón Bolívar and Thomas Jefferson. Wulf examines how Humboldt's writings inspired other naturalists and poets such as Darwin, Wordsworth, and Goethe, and she makes the compelling case that it was Humboldt's influence that led John Muir to his ideas of natural preservation and that shaped Thoreau's Walden.With this brilliantly researched and compellingly written book, Andrea Wulf shows the myriad fundamental ways in which Humboldt created our understanding of the natural world, and she champions a renewed interest in this vital and lost player in environmental history and science.

    He was also a man obsessed. He spent his life idolizing Ernest Shackleton, the nineteenth-century polar explorer, who tried to become the first person to reach the South Pole, and later sought to cross Antarctica on foot. Shackleton never completed his journeys, but he repeatedly rescued his men from certain death, and emerged as one of the greatest leaders in history.Worsley felt an overpowering connection to those expeditions. He was related to one of Shackleton's men, Frank Worsley, and spent a fortune collecting artifacts from their epic treks across the continent. He modeled his military command on Shackleton's legendary skills and was determined to measure his own powers of endurance against them. He would succeed where Shackleton had failed, in the most brutal landscape in the world.In 2008, Worsley set out across Antarctica with two other descendants of Shackleton's crew, battling the freezing, desolate landscape, life-threatening physical exhaustion, and hidden crevasses. Yet when he returned home he felt compelled to go back. On November 2015, at age 55, Worsley bid farewell to his family and embarked on his most perilous quest: to walk across Antarctica alone.

    For centuries, Antarctica has captured the imagination of our greatest scientists and explorers, lingering in the spirit long after their return. Shackleton called it "the last great journey"; for Apsley Cherry-Garrard it was the worst journey in the world. This is a book about the call of the wild and the response of the spirit to a country that exists perhaps most vividly in the mind. Sara Wheeler spent seven months in Antarctica, living with its scientists and dreamers. No book is more true to the spirit of that continent--beguiling, enchanted and vast beyond the furthest reaches of our imagination. Chosen by Beryl Bainbridge and John Major as one of the best books of the year, recommended by the editors of Entertainment Weekly and the Chicago Tribune, one of the Seattle Times's top ten travel books of the year, Terra Incognita is a classic of polar literature.

    They attracted followers ranging from Thomas Jefferson, who laid out mastodon bones on the White House floor, to twentieth-century doctors who used their knowledge of new species to conquer epidemic diseases. Acclaimed science writer Richard Conniff brings these daredevil "species seekers" to vivid life. Alongside their globe-spanning tales of adventure, he recounts some of the most dramatic shifts in the history of human thought. At the start, everyone accepted that the Earth had been created for our benefit. We weren't sure where vegetable ended and animal began, we couldn't classify species, and we didn't understand the causes of disease. But all that changed as the species seekers introduced us to the pantheon of life on Earth—and our place within it.

    An ancient curse. A stunning medical mystery. And a pioneering journey into the unknown heart of the world's densest jungle.Since the days of conquistador Hernán Cortés, rumors have circulated about a lost city of immense wealth hidden somewhere in the Honduran interior, called the White City or the Lost City of the Monkey God. Indigenous tribes speak of ancestors who fled there to escape the Spanish invaders, and they warn that anyone who enters this sacred city will fall ill and die. In 1940, swashbuckling journalist Theodore Morde returned from the rainforest with hundreds of artifacts and an electrifying story of having found the Lost City of the Monkey God-but then committed suicide without revealing its location.Three quarters of a century later, author Doug Preston joined a team of scientists on a groundbreaking new quest. In 2012 he climbed aboard a rickety, single-engine plane carrying the machine that would change everything: lidar, a highly advanced, classified technology that could map the terrain under the densest rainforest canopy. In an unexplored valley ringed by steep mountains, that flight revealed the unmistakable image of a sprawling metropolis, tantalizing evidence of not just an undiscovered city but an enigmatic, lost civilization.Venturing into this raw, treacherous, but breathtakingly beautiful wilderness to confirm the discovery, Preston and the team battled torrential rains, quickmud, disease-carrying insects, jaguars, and deadly snakes. But it wasn't until they returned that tragedy struck: Preston and others found they had contracted in the ruins a horrifying, sometimes lethal-and incurable-disease.

    Thus began the legendary ordeal of Shackleton and his crew of twenty-seven men. When their ship was finally crushed between two ice floes, they attempted a near-impossible journey over 850 miles of the South Atlantic's heaviest seas to the closest outpost of civilization.In Endurance, the definitive account of Ernest Shackleton's fateful trip, Alfred Lansing brilliantly narrates the harrowing and miraculous voyage that has defined heroism for the modern age.

    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.
