An enthralling and extraordinary adventure vividly charting the mysteries of the deep Earth, the history of our planet, and the latest discoveries about its inner core. The journey to the center of the earth is a voyage like no other we can imagine. Over 3000 km below the earth's surface, an extraordinary inner world the size of Mars awaits us. Dive through the molten iron of the outer core and eventually you will reach a solid sphere —an iron-clad world held within a metal sea and unattached to anything above. At the earth's core is the history of our planet written in temperature and pressure, crystals and minerals ... Our planet appears tranquil from outer space. And yet the arcs of volcanoes, the earthquake zones, and the auroral glow rippling above our heads are testimony to the remarkable happenings within the earth’s core. For thousands of years these phenomena were explained in legend and myth. Only in recent times has the brave new science of seismology emerged. One hundred and fifty years after the extraordinary, imaginative feat of Jules Verne's Journey to the Center of the Earth, David Whitehouse embarks on a voyage of scientific discovery into the heart of our world. Seismologists today reveal a planet astonishingly buried within a planet. We watch as supercomputers convert signals from the ground into three-dimensional scans of subterranean continents. We will visit laboratories where scientists attempt to reproduce the intense conditions at the center of the Earth, travel down the throat of a volcano, look into the deepest hole ever drilled, and imagine a voyage through enormous crystals of iron...all at the center of our incredible Earth.

Survival narrative meets scientific, natural, and social history in the riveting story of a volcanic disaster. For months in early 1980, scientists, journalists, sightseers, and nearby residents listened anxiously to rumblings in Mount St. Helens, part of the chain of western volcanoes fueled by the 700-mile-long Cascadia fault. Still, no one was prepared when an immense eruption took the top off of the mountain and laid waste to hundreds of square miles of verdant forests in southwestern Washington State. The eruption was one of the largest in human history, deposited ash in eleven U.S. states and five Canadian provinces, and caused more than one billion dollars in damage. It killed fifty-seven people, some as far as thirteen miles away from the volcano’s summit. Shedding new light on the cataclysm, author Steve Olson interweaves the history and science behind this event with page-turning accounts of what happened to those who lived and those who died. Powerful economic and historical forces influenced the fates of those around the volcano that sunny Sunday morning, including the construction of the nation’s railroads, the harvest of a continent’s vast forests, and the protection of America’s treasured public lands. The eruption of Mount St. Helens revealed how the past is constantly present in the lives of us all. At the same time, it transformed volcanic science, the study of environmental resilience, and, ultimately, our perceptions of what it will take to survive on an increasingly dangerous planet. Rich with vivid personal stories of lumber tycoons, loggers, volcanologists, and conservationists, Eruption delivers a spellbinding narrative built from the testimonies of those closest to the disaster, and an epic tale of our fraught relationship with the natural world.

Our most compelling resource just might be the ground beneath our feet. When a teaspoon of soil contains millions of species, and when we pave over the earth on a daily basis, what does that mean for our future? What is the risk to our food supply, the planet's wildlife, the soil on which every life-form depends? How much undeveloped, untrodden ground do we even have left? Paul Bogard set out to answer these questions in The Ground Beneath Us, and what he discovered is astounding. From New York (where more than 118,000,000 tons of human development rest on top of Manhattan Island) to Mexico City (which sinks inches each year into the Aztec ruins beneath it), Bogard shows us the weight of our cities' footprints. And as we see hallowed ground coughing up bullets at a Civil War battlefield; long-hidden remains emerging from below the sites of concentration camps; the dangerous, alluring power of fracking; the fragility of the giant redwoods, our planet's oldest living things; the surprises hidden under a Major League ballpark's grass; and the sublime beauty of our few remaining wildest places, one truth becomes blazingly clear: The ground is the easiest resource to forget, and the last we should. Bogard's The Ground Beneath Us is deeply transporting reading that introduces farmers, geologists, ecologists, cartographers, and others in a quest to understand the importance of something too many of us take for granted: dirt. From growth and life to death and loss, and from the subsurface technologies that run our cities to the dwindling number of idyllic Edens that remain, this is the fascinating story of the ground beneath our feet.

There once may have been 250,000 miles of stone walls in America's Northeast, stretching farther than the distance to the moon. They took three billion man-hours to build. And even though most are crumbling today, they contain a magnificent scientific and cultural story-about the geothermal forces that formed their stones, the tectonic movements that brought them to the surface, the glacial tide that broke them apart, the earth that held them for so long, and about the humans who built them. Stone walls layer time like Russian dolls, their smallest elements reflecting the longest spans, and Thorson urges us to study them, for each stone has its own story. Linking geological history to the early American experience, Stone by Stone presents a fascinating picture of the land the Pilgrims settled, allowing us to see and understand it with new eyes.
