    In the winter of 1983, the largest El Niño event on record—a chain of “superstorms” that swept in from the Pacific Ocean—battered the entire West. That spring, a massive snowmelt sent runoff racing down the Colorado River toward the Glen Canyon Dam, a 710-foot-high wall of concrete that sat at the head of the most iconic landscape feature in America, the Grand Canyon. As the water clawed toward the parapet of the dam, worried federal officials desperately scrambled to avoid a worst-case scenario: one of the most dramatic dam failures in history. In the midst of this crisis, beneath the light of a full moon, a trio of river guides secretly launched a small, hand-built wooden boat, a dory named the Emerald Mile, into the Colorado just below the dam’s base and rocketed toward the dark chasm downstream, where the torrents of water released by the dam engineers had created a rock-walled maelstrom so powerful it shifted giant boulders and created bizarre hydraulic features never previously seen. The river was already choked with the wreckage of commercial rafting trips: injured passengers clung to the remnants of three-ton motorboats that had been turned upside down and torn to pieces. The chaos had claimed its first fatality, further launches were forbidden, and rangers were conducting the largest helicopter evacuation in the history of Grand Canyon National Park. An insurgent river run under such conditions seemed to border on the suicidal, but Kenton Grua, the captain of that dory, was on an unusual mission: a gesture of defiance unlike anything the river world had ever seen. His aim was to use the flood as a hydraulic slingshot that would hurl him and two companions through 277 miles of some of the most ferocious white water in North America and, if everything went as planned, catapult the Emerald Mile into legend as the fastest boat ever propelled—by oar, by motor, or by the grace of God—through the heart of the Grand Canyon. Grua himself was already something of a mythic figure, a fearless boatman obsessed with the mysteries of the canyon. His quest embraced not only the trials of the speed run itself but also the larger story of his predecessors: the men who had first discovered the canyon and pioneered its exploration, as well as those who waged a landmark battle to prevent it from being hog-tied by a series of massive hydroelectric dams—a conflict that continues to this day. A writer who has worked as a river guide himself and is intimately familiar with the canyon’s many secrets, Kevin Fedarko is the ideal narrator for this American epic. The saga of The Emerald Mile is a thrilling adventure, as well as a magisterial portrait of the hidden kingdom of white water at the bottom of the greatest river canyon on earth. This book announces Fedarko as a major writing talent and at last sets forth the full story of an American legend—the legend of The Emerald Mile.

    Its geology, its unique flora and fauna, and its striking role in human history intersect in surprising and dynamic ways. This book is the most wide-ranging and beautifully illustrated book available on the famous islands. Not since Darwin’s Naturalist’s Voyage has a book combined so much scientific and historic information with firsthand accounts that bring the Galápagos to life.Galápagos: The Islands That Changed the World describes how tragedy and murderous pirates curtailed settlement of the islands and how the islands’ pristine nature, spectacular geology, and defining isolation inspired Darwin’s ideas about evolution. The book explores the diverse land and marine habitats that shelter Galápagos species and considers the islands’ importance today as a frontier for science and a refuge for true wilderness. The book’s extensive gazetteer provides details about endemic plants and animals as well as travel advice about visitors’ sites, diving, photography, when to go, and what to take. Vividly illustrated throughout, this guide is an indispensable reference for natural history enthusiasts, armchair travelers, and island visitors alike.

    These torchlight adventures have since inspired a generation of scientists, and his research is still considered useful today. In The Secret Life of Wombats, James Woodford pursues Nicholson's story and embarks on his own journey to uncover the true nature of our most intriguing marsupial."Woodford has done the research, he has read widely, spoken with the major wombat pundits and with the lay observers. He has travelled to gain direct experience of all species...I know more about wombats than I did, and retain some stark images which I hope never to lose." - Sunday 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.

    Someone [the murderer?] had covered him with a small strip of carpet.Nearby, in a ditch,lay Mrs Chandler - her face and torso bafflingly blanketed in beer cartons.The discovery made international headlines. It swiftly emerged that Dr Bogle, a brilliant specialist in solid state physics, had recently accepted a research post in Washington – and had been preparing to fly there, with his wife and children. Mrs Chandler, who’d worked as a nurse before her marriage, had been at the same New Year’s party with Gilbert Bogle the evening before. They had left separately.Scientists found that the pair had died of acute heart failure – but they could suggest no cause. There were no signs of violence: no smothering or strangulation; no hypodermic marks; no evidence, in the body tissues, of poisons, or radioactive substances of any kind.From the morning the bodies were found, the Bogle-Chandler conundrum would perplex the law’s keenest forensic minds...

    Learning all the tongue twisting names, picking favorites based on ferocity, armor, or sheer size. For many kids this love of ‘terrible lizards’ fizzles out at some point between starting and leaving primary school. All those fancy names slowly forgotten, no longer any need for a favorite.For all those child dino fanatics who didn’t grow up to become paleontologists, dinosaurs seem like something out of mythology. They are dragons, pictures in books, abstract, other, extinct.They are at the same time familiar and mysterious. And yet we’re in an age of rapid discovery—new dinosaur species and genera are being discovered at an accelerating rate, we’re learning more about what they looked like, how they lived, how they evolved and where they all went.This series isn’t just a top trumps list of dino facts—we’re interested in the why and the how and like all areas of science there is plenty of controversy and debate.

    Gillet, at the age of 36 an accomplished sailor and paddler, navigated by sextant and always knew his position within a few miles. Still, Gillet underestimated the abuse his body would take from the relentless, pounding, swells of the Pacific, and early into his voyage he was covered with salt water sores and found that he could find no comfortable position for sitting or sleeping. Along the way he endured a broken rudder, among other calamities, but at last reached Maui on his 63rd day at sea, four days after his food had run out. Dave Shively brings Gillet's remarkable story to life in this gripping narrative, based on exclusive access to Gillet's logs as well as interviews with the legendary paddler himself.

    The son of an abolitionist preacher, a Civil War hero (who lost an arm at Shiloh), and a passionate naturalist and geologist, in 1869 Powell tackled the vast and dangerous gorge carved by the Colorado River and known today (thanks to Powell) as the Grand Canyon.With The Promise of the Grand Canyon, John Ross recreates Powell's expedition in all its glory and terror, but his second (unheralded) career as a scientist, bureaucrat, and land-management pioneer concerns us today. Powell was the first to ask: how should the development of the west be shaped? How much could the land support? What was the role of the government and private industry in all of this? He began a national conversation about sustainable development when most everyone else still looked upon land as an inexhaustible resource. Though he supported irrigation and dams, his prescient warnings forecast the 1930s dustbowl and the growing water scarcities of today. Practical, yet visionary, Powell didn't have all the answers, but was first to ask the right questions.
