The Los Angeles Times has listed it among the one hundred most influential books published in the last quarter century, Outside Magazine has included it in a survey of books that changed our world, and it has been called the Book of Genesis for environmentalists. Now a fourth edition of this highly regarded work is available, with a new preface and epilogue in which Nash explores the future of wilderness and reflects on its ethical and biocentric relevance.

    Cahill stumbles from glacier to geyser, encounters wildlife, muses on the microbiology of thermal pools, and sees moonbows arcing across waterfalls at midnight.

    His thrilling narrative takes us into the bear's habitat, where we observe directly this majestic animal's behavior, from hunting strategies, mating patterns, and denning habits to social hierarchy and methods of communication. As Peacock tracks the bears, his story turns into a thrilling narrative about the breaking down of suspicion between man and beast in the wild.

    Vesuvius, whose eruption in Roman times helped spark the science of geology, and ending in a lab in the West of England where mathematical models and lab experiments replace direct observation, Richard Fortey tells us what the present says about ancient geologic processes. He shows how plate tectonics came to rule the geophysical landscape and how the evidence is written in the hills and in the stones. And in the process, he takes us on a wonderful journey around the globe to visit some of the most fascinating and intriguing spots on the planet.

    Spending nearly half the year in a 7' x 7' tower, 10,000 feet above sea level in remote New Mexico, his tasks were simple: keep watch over one of the most fire-prone forests in the country and sound the alarm at the first sign of smoke.Fire Season is Connors's remarkable reflection on work, our place in the wild, and the charms of solitude. The landscape over which he keeps watch is rugged and roadless — it was the first region in the world to be officially placed off limits to industrial machines — and it typically gets hit by lightning more than 30,000 times per year. Connors recounts his days and nights in this forbidding land, untethered from the comforts of modern life: the eerie pleasure of being alone in his glass-walled perch with only his dog Alice for company; occasional visits from smokejumpers and long-distance hikers; the strange dance of communion and wariness with bears, elk, and other wild creatures; trips to visit the hidden graves of buffalo soldiers slain during the Apache wars of the nineteenth century; and always the majesty and might of lightning storms and untamed fire.Written with narrative verve and startling beauty, and filled with reflections on his literary forebears who also served as lookouts — among them Edward Abbey, Jack Kerouac, Norman Maclean, and Gary Snyder — Fire Season is a book to stand the test of time.

    Naturalist Ellen Meloy tracks a band of these majestic creatures through backcountry hikes, downriver floats, and travels across the Southwest. Alone in the wilderness, Meloy chronicles her communion with the bighorns and laments the growing severance of man from nature, a severance that she feels has left us spiritually hungry. Wry, quirky and perceptive, Eating Stone is a brillant and wholly original tribute to the natural world.

    Houston’s ranch becomes her sanctuary, a place where she discovers how the natural world has mothered and healed her after a childhood of parental abuse and neglect.In a work as lucid and invigorating as mountain air, Deep Creek delivers Houston’s most profound meditations yet on how “to live simultaneously inside the wonder and the grief . . . to love the damaged world and do what I can to help it thrive.”

    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.

    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.

    Written by a passionate and professional geologist who has spent countless hours in the field exploring and photographing the state, In Search of Ancient Oregon is a book for all those interested in Oregon's landscapes and environments. It presents fine-art-quality color photographs of well-known features such as Mount Hood, Crater Lake, Smith Rock, Steens Mountain, the Columbia River Gorge, and Cannon Beach, and scenic, not so well known places such as Jordan Craters, Leslie Gulch, Abert Rim, Hells Canyon, Elkhorn Mountains, and Three Fingered Jack. Each of the more than 220 stunning photographs is accompanied by readable text, presenting the story of how Oregon's diverse landscapes evolved — and what we may expect in the future. Until now, no book has presented this dynamic story in a way that everyone interested in Oregon's natural history can easily understand. The combination of extraordinary photographs and the author's lucid explanations make this book both unique and essential for those curious about our own contemporary landscape.

    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.

    This is a radiant and deeply moving account of a "true pilgrimage, a journey of the heart."

    It presents the important traditional content of mineralogy including crystallography, chemical bonding, controls on mineral structure, mineral stability, and crystal growth to provide a foundation that enables students to understand the nature and occurrence of minerals. Physical, optical, and X-ray powder diffraction techniques of mineral study are described in detail, and common chemical analytical methods are outlined as well. Detailed descriptions of over 100 common minerals are provided, and the geologic context within which these minerals occur is emphasized. Appendices provide tables and diagrams to help students with mineral identification, using both physical and optical properties. Numerous line drawings, photographs, and photomicrographs help make complex concepts understandable. Introduction to Mineralogy not only provides specific knowledge about minerals but also helps students develop the intellectual tools essential for a solid, scientific education. This comprehensive text is useful for undergraduate students in a wide range of mineralogy courses.

    The prairies are the heartland of the continent, a vast, windswept plain that flows from Alberta south to Texas and from the Rockies east to the Mississippi River. This is big sky country, and until recently, one of the richest and most magnificent natural grasslands in the world. Today, however, the North American prairies are among the most altered environments on Earth. Thorough, detailed, and scientifically up-to-date, Prairie: A Natural History provides a comprehensive, nontechnical guide to the biology and ecology of this fabled environment, offering a view of the past, a vision for the future, and a clear focus on the present. Sidebars throughout highlight various grasslands species, tell fascinating natural history and conservation stories, and present the traditional Native American view of the prairie and its inhabitants.

    Harlen Bretz walked the dry scabland channels of eastern Washington in the 1920s, it dawned on him that he was viewing a landscape sculpted by water. Lots of water. A flood of catastrophic proportions. Glacial Lake Missoula and Its Humongous Floods tells the gripping tale of a huge Ice Age lake that drained suddenly--not just once but repeatedly--and reshaped the landscape of the Northwest. The narrative follows the path of the floodwaters as they raged from western Montana across the Idaho Panhandle, then scoured through eastern Washington and down the Columbia Gorge to the Pacific Ocean. This is also the story of geologists grappling with scientific controversy--"of how personalities, pride, and prejudice sometimes superseded scientific evidence."
