This is the only book to clearly illustrate and systematically guide readers through glacier anatomy, equipment, route finding, and rescue techniques and, just like our other books that are illustrated by Mike Clelland, it is guaranteed to entertain the whole way through.

    Belknap's Waterproof Grand Canyon River Guide (All New Color Edition)

    Legendary geologist J Harlen Bretz was the first to explore the area, starting in the 1920s. This dramatic book tells the story of this scientific maverick — how he came to study the region, his radical theory that a flood of biblical proportions created it, and how a campaign by the mainstream geologic community tried to derail him for pursuing an idea that satellite photos would confirm decades later.

    Only five survived.Journalist Andy Hall, son of the park superintendent at the time, investigates the tragedy. He spent years tracking down survivors, lost documents, and recordings of radio communications. In Denali’s Howl, Hall reveals the full story of an expedition facing conditions conclusively established here for the first time: At an elevation of nearly 20,000 feet, these young men endured an “arctic super blizzard,” with howling winds of up to 300 miles an hour and wind chill that freezes flesh solid in minutes. All this without the high-tech gear and equipment climbers use today.As well as the story of the men caught inside the storm, Denali’s Howl is the story of those caught outside it trying to save them—Hall’s father among them. The book gives readers a detailed look at the culture of climbing then and now and raises uncomfortable questions about each player in this tragedy. Was enough done to rescue the climbers, or were their fates sealed when they ascended into the path of this unprecedented storm?

    Chris O’Brien presents the case for beer as both the cause of and solution to all of the world’s problems. Beer has contributed to the best qualities of civilization, but it is also helping to destroy them.The global beer industry relies heavily on fossil-fuels and chemical agriculture, rapidly destroying nature and contributing to climate change.Corporate beer is centralized and hierarchical, which is good for a few elites, but displaces local brewing traditions and exacerbates the growing wealth gap.But the craft brewing renaissance relies on cooperation, emphasizes local production, protects and celebrates nature, and nurtures the growth of strong and equitable communities.Fermenting Revolution traces the path of brewing from a women-led, home-based craft to corporate industry, and describes how modern craft breweries and home-brewers are forging stronger communities. O’Brien explains how corporate mega-breweries are also taking steps to pioneer industrial ecology, and profiles the most inspiring and radical breweries, brewers, and beer drinkers that are making the world a better place to live.In the last two decades, Americans have returned to to beer as a way of life rather than as a commodity. Casting off its industrial chains, beer is again communal, convivial, democratic, healthful, and natural. The contemporary American brewing scene champions ecologically sustainable production and is helping to create thriving community places. After reading Fermenting Revolution, mere beer drinkers will become "beer activists," ready to fight corporate rule by simply meeting their neighbors for a pint at the local brewpub-saving the world one beer at a time.

    One follows geological research that challenged the scientific paradigm of the early 20th century, and the other chronicles the result of that research: the discovery of powerful prehistoric floods that shaped the Pacific Northwest. The cataclysms at the end of the last Ice Age left a scabland of buttes, dry falls, and rocky gorges, but it took the detective work of geologist J Harlen Bretz to prove it to the world. His lifetime of research and unshakeable belief changed geology forever.

    In 1969 we even walked on the moon. And yet as late as 2000, the earth’s deepest cave—the supercave—remained undiscovered. This is the story of the men and women who risked everything to find it, earning their place in history beside the likes of Peary, Amundsen, Hillary, and Armstrong. In 2004, two great scientist-explorers are attempting to find the bottom of the world. Bold, heroic American Bill Stone is committed to the vast Cheve Cave, located in southern Mexico and deadly even by supercave standards. On the other side of the globe, legendary Ukrainian explorer Alexander Klimchouk—Stone’s polar opposite in temperament and style, but every bit his equal in scientific expertise, physical bravery, and sheer determination—has targeted Krubera, a freezing nightmare of a supercave in the Republic of Georgia, where underground dangers are compounded by the horrors of separatist war in this former Soviet republic.

    Sometimes grizzlies kill people, and in exceptionally rare cases they even eat them. Those incidents are the focus of this book because that's what makes bears so interesting, such a huge part of our culture and our collective imagination.

    Helens in southwestern Washington State. Still, no one was prepared when a cataclysmic eruption blew the top off of the mountain, laying waste to hundreds of square miles of land and killing fifty-seven people. Steve Olson interweaves vivid personal stories with the history, science, and economic forces that influenced the fates and futures of those around the volcano. Eruption delivers a spellbinding narrative of an event that changed the course of volcanic science, and an epic tale of our fraught relationship with the natural world.

    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.

    It was to last five years and transform him from an amiable and somewhat aimless young man into a scientific celebrity. Even more vitally, it was to set in motion the intellectual currents that culminated in the arrival of The Origin of Species in Victorian drawing-rooms in 1859. His journal, reprinted here in a shortened version, is vivid and immediate, showing us a naturalist making patient observations, above all in geology. As well as a profusion of natural history detail, it records many other things that caught Darwin’s eye, from civil war in Argentina to the new colonial settlements of Australia. The editors have provided an excellent introduction and notes for this Penguin Classics edition, which also contains maps and appendices, including an essay on scientific geology and the Bible by Robert FitzRoy, Darwin’s friend and captain of the Beagle.

    But they are under threat as never before, and their problems are spreading across the continent. The Death and Life of the Great Lakes is prize-winning reporter Dan Egan’s compulsively readable portrait of an ecological catastrophe happening right before our eyes, blending the epic story of the lakes with an examination of the perils they face and the ways we can restore and preserve them for generations to come.

    Rachel Carson's rare ability to combine scientific insight with moving, poetic prose catapulted her book to first place on The New York Times best-seller list, where it enjoyed wide attention for thirty-one consecutive weeks. It remained on the list for more than a year and a half and ultimately sold well over a million copies, has been translated into 28 languages, inspired an Academy Award-winning documentary, and won both the 1952 National Book Award and the John Burroughs Medal.This classic work remains as fresh today as when it first appeared. Carson's writing teems with stunning, memorable images--the newly formed Earth cooling beneath an endlessly overcast sky; the centuries of nonstop rain that created the oceans; giant squids battling sperm whales hundreds of fathoms below the surface; and incredibly powerful tides moving 100 billion tons of water daily in the Bay of Fundy. Quite simply, she captures the mystery and allure of the ocean with a compelling blend of imagination and expertise.Reintroducing a classic work to a whole new generation of readers, this Special Edition features a new chapter written by Jeffrey Levinton, a leading expert in marine ecology, that brings the scientific side of The Sea Around Us completely up to date. Levinton incorporates the most recent thinking on continental drift, coral reefs, the spread of the ocean floor, the deterioration of the oceans, mass extinction of sea life, and many other topics. In addition, acclaimed nature writer Ann Zwinger has contributed a brief foreword.Today, with the oceans endangered by the dumping of medical waste and ecological disasters such as the Exxon oil spill in Alaska, this illuminating volume provides a timely reminder of both the fragility and the importance of the ocean and the life that abounds within it. Anyone who loves the sea, or who is concerned about our natural environment, will want to read this classic work.

    But in the full history of life, ancient animals, even the trilobites, form only the half-billion-year tip of a nearly four-billion-year iceberg. Andrew Knoll explores the deep history of life from its origins on a young planet to the incredible Cambrian explosion, presenting a compelling new explanation for the emergence of biological novelty. The very latest discoveries in paleontology--many of them made by the author and his students--are integrated with emerging insights from molecular biology and earth system science to forge a broad understanding of how the biological diversity that surrounds us came to be. Moving from Siberia to Namibia to the Bahamas, Knoll shows how life and environment have evolved together through Earth's history. Innovations in biology have helped shape our air and oceans, and, just as surely, environmental change has influenced the course of evolution, repeatedly closing off opportunities for some species while opening avenues for others. Readers go into the field to confront fossils, enter the lab to discern the inner workings of cells, and alight on Mars to ask how our terrestrial experience can guide exploration for life beyond our planet. Along the way, Knoll brings us up-to-date on some of science's hottest questions, from the oldest fossils and claims of life beyond the Earth to the hypothesis of global glaciation and Knoll's own unifying concept of ''permissive ecology.'' In laying bare Earth's deepest biological roots, Life on a Young Planet helps us understand our own place in the universe--and our responsibility as stewards of a world four billion years in the making.In a new preface, Knoll describes how the field has broadened and deepened in the decade since the book's original publication.
