    This story of a fascinating landscape is told in an engaging style that nonscientists will find inviting. The story’s end, however, remains a mystery yet to be solved.

    It also contains one of the world's largest supplies of natural gas, a resource that has been dismissed as inaccessible until recently. Technological developments that combine horizontal drilling with hydraulic fracturing ("fracking") have removed physical and economic barriers to extracting hundreds of trillions of cubic feet of gas from bedrock deep below the Appalachian basin. Beginning in 2006, the first successful Marcellus gas wells by Range Resources, combined with a spike in the value of natural gas, spurred a modern-day gold rush a "gas rush" with profound ramifications for environmental policy, energy markets, political dynamics, and the lives of the people living in the Marcellus region. Under the Surface is the first book-length journalistic overview of shale gas development and the controversies surrounding it.Control over drilling rights is at stake in the heart of Marcellus country northeast Pennsylvania and central New York. The decisions by landowners to work with or against the companies and the resulting environmental and economic consequences are scrutinized by neighbors faced with similar decisions, by residents of cities whose water supply originates in the exploration area, and by those living across state lines with differing attitudes and policies concerning extraction industries. Wilber's evenhanded treatment gives a voice to all constituencies, including farmers and landowners tempted by the prospects of wealth but wary of the consequences, policymakers struggling with divisive issues, and activists coordinating campaigns based on their respective visions of economic salvation and environmental ruin. Wilber describes a landscape in which the battle over the Marcellus ranges from the very local yard signs proclaiming landowners' allegiances for or against shale gas development to often conflicting municipal, state, and federal legislation intended to accelerate, delay, or discourage exploration.For millions of people with a direct stake in shale gas exploration in the Marcellus or any number of other emerging shale resources in the United States and worldwide, or for those concerned about the global energy outlook, Under the Surface offers a worthwhile and engaging look at the issues.

    As Williams tried to escape the blast, he was pelted with white-hot projectiles traveling faster than bullets. Within seconds he was cut down, his skull fractured, his right leg almost severed, his backpack aflame. Williams lay helpless and near death on Galeras's flank until two brave women -- friends and fellow volcanologists -- mounted an astonishing rescue effort to carry him safely off the mountain.The tale of how Williams survived Galeras is the framework for a groundbreaking book about volcanoes, their physical and cultural impact, and the tiny cadre of scientists who risk their own lives to gain knowledge that might one day save many others' lives.--BOOK JACKET

    Alvarez had the first glimmer of that amazing insight when he noticed something odd in a rock outcrop in central Italy. Alvarez now returns to that rich terrain, this time to take the reader on an excavation of the Earth's distant past. We encounter the volcanoes that formed the Seven Hills of Rome; the majestic limestone Apennine mountains that started to develop millions of years ago under water; the evidence that the Mediterranean Sea completely evaporated to a sunken desert, perhaps several times; and the proof that continental plates once overran one another to form the Alps. In Alvarez's telling, all major geologic episodes are as dramatic as the great impact that killed the dinosaurs, even when they happen over eons and without huge creatures to witness them.

    Solid anchors and proper rope techniques can prevent a fall from turning into a catastrophe, while bad anchors are an accident waiting to happen," says certified guide Craig Luebben, who invented his own type of climbing protection, the Big Bro. Since then, he taught rock climbing to hundreds of clients and has conducted self-rescue clinics across the United States. He distills more than twenty-five years of experience into Rock Climbing Anchors.This entry in the Mountaineers Outdoor Expert Series, for intermediate-to-advanced climbers, presents modern anchoring ideas and techniques for top-roping, rappelling, sport climbing, traditional rock climbing, and mountaineering-all in one comprehensive guide. Luebben covers the finer points of all types of commonly used anchors: removable anchors including hexes, wired nuts, tri-cams, expanding wedges, expandable tubes, and cams; natural anchors such as trees and boulders; and fixed anchors like bolts and pitons. Photos show a variety of gear placements, accompanied by discussion of the pros and cons of each.

    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.

    The only ones who can find and stop him are the forensic geologists, and they are up against more than pure human malice. The unstable atom--in the hands of an unstable man--is governed by Murphy's Law. Whatever can go wrong, will go wrong.VOLCANO WATCHThe volcano beneath the geologists' home town is seething, and the mayor is found murdered with a note saying NO WAY OUT. The fate of the town now rests in the hands of an emergency planner with his own twisted agenda. As the volcano moves toward red alert, the geologists race to prevent 'no way out' from becoming a prophecy.

    But to a geologist, stones are richly illustrated narratives, telling gothic tales of cataclysm and reincarnation. For more than four billion years, in beach sand, granite, and garnet schists, the planet has kept a rich and idiosyncratic journal of its past. Fulbright Scholar Marcia Bjornerud takes the reader along on an eye-opening tour of Deep Time, explaining in elegant prose what we see and feel beneath our feet. Both scientist and storyteller, Bjornerud uses anecdotes and metaphors to remind us that our home is a living thing with lessons to teach. She shows how our planet has long maintained a delicate balance, and how the global give-and-take has sustained life on Earth through numerous upheavals. But with the rapidly escalating effects of human beings on their home planet, that cosmic balance is being threatened -- and the consequences may be catastrophic. Containing a glossary and detailed timescale, as well as vivid descriptions and historic accounts, Reading the Rocks is literally a history of the world, for all friends of the Earth.

    The result is The Backbone of the World, an arresting exploration of America’s longest wilderness corridor, a harsh and unforgiving region inhabited by men and women whose way of life is as imperiled as the neighboring wildlife. With the brutal beauty and stark cadences of a Cormac McCarthy novel, The Backbone of the World tells the story of the last remnants of the Old West, America’s mythic landscape, where past and present are barely discernible from one another and where people’s lives are still intrinsically linked to their natural surroundings. Clifford vividly captures the challenges of life along the Divide today through portraits of memorable characters: a ranching family whose isolated New Mexico homestead has become a mecca for illegal immigrants and drug smugglers; a sheep herder struggling to make a living tending his flock in the mountains above Vail, Colorado: an old mule packer who has spent years scouring the mountains of northwest Wyoming for the downed plane of his son; a Yellowstone Park ranger on a lone crusade to protect elk and grizzly bears from illegal hunters; and a group of Blackfeet Indians in northern Montana who are fearful that a wilderness sanctuary will be lost to oil and gas development. In each of their stories, the tide of change is looming as environmental, economic, social, and political forces threaten this uniquely unfettered population. Clifford’s participatory approach offers a haunting and immediate evocation of character and geography and an unsentimental eulogy to the people whose disappearance will sever a link with the defining American pioneer spirit. Set in a world of isolated ranches, trail camps, mountain bivouacs, and forgotten hamlets, The Backbone of the World highlights the frontier values that have both ennobled and degraded us, values that symbolize the last breath of our founding character.From the Hardcover edition.
