Public interest in the first lunar landing transcended political, economic and social borders – the world was briefly united by the courage of the crew, and the wonder of the accomplishment. Prompted by the rivalry of the Cold War, Apollo 11 and the five missions that subsequently landed on the Moon were arguably the finest feats of exploration in human history.

But these were more than exercises in ‘flags and footprints’, because the missions involved the crews making geological field trips on a low gravity site while wearing pressure suits, carrying life-support systems on their backs and working against an unforgiving time line. The missions delivered not only samples of moonrock, but also hard-learned lessons for how to work on the surface of another planet, and this experience will be crucial to planning the resumption of the human exploration of the Moon and going on to Mars.

Whenever a volcano threatens to erupt, scientists and adventurers from around the world flock to the site in response to the irresistible allure of one of nature''s most dangerous and unpredictable phenomena. In a unique book probing the science and mystery of these fiery features, the authors chronicle not only their geologic behavior but also their profound effect on human life. From Mount Vesuvius to Mount St. Helens, the book covers the surprisingly large variety of volcanoes, the subtle to conspicuous signs preceding their eruptions, and their far-reaching atmospheric consequences. Here scientific facts take on a very human dimension, as the authors draw upon actual encounters with volcanoes, often through firsthand accounts of those who have witnessed eruptions and miraculously survived the aftermath. The book begins with a description of the lethal May 1980 eruption of Mount St. Helens--complete with an explanation of how safety officials and scientists tried to predict events, and how unsuspecting campers and loggers miles away struggled against terrifying blasts of ash, stone, and heat. The story moves quickly to the ways volcanoes have enhanced our lives, creating mineral-rich land, clean thermal energy, and haunting landscapes that in turn benefit agriculture, recreation, mining, and commerce. Religion and psychology embroider the account, as the authors explore the impact of volcanoes on the human psyche through tales of the capricious volcano gods and attempts to appease them, ranging from simple homage to horrific ritual sacrifice. Volcanoes concludes by assisting readers in experiencing these geological phenomena for themselves. An unprecedented "tourist guide to volcanoes" outlines over forty sites throughout the world. Not only will travelers find information on where to go and how to get there, they will also learn what precautions to take at each volcano. Tourists, amateur naturalists, and armchair travelers alike will find their scientific curiosity whetted by this informative and entertaining book.

From humble beginnings, Rome became perhaps the greatest intercontinental power in the world. Why did this historic city become so much more influential than its neighbor, nearby Latium, which was peopled by more or less the same stock? Over the years, historians, political analysts, and sociologists have discussed this question ad infinitum, without considering one underlying factor that led to the rise of Rome--the geology now hidden by the modern city. This book demonstrates the important link between the history of Rome and its geologic setting in a lively, fact-filled narrative sure to interest geology and history buffs and travelers alike. The authors point out that Rome possessed many geographic advantages over surrounding areas: proximity to a major river with access to the sea, plateaus for protection, nearby sources of building materials, and most significantly, clean drinking water from springs in the Apennines. Even the resiliency of Rome''s architecture and the stability of life on its hills are underscored by the city''s geologic framework. If carried along with a good city map, this book will expand the understanding of travelers who explore the eternal city''s streets. Chapters are arranged geographically, based on each of the seven hills, the Tiber floodplain, ancient creeks that dissected the plateau, and ridges that rise above the right bank. As an added bonus, the last chapter consists of three field trips around the center of Rome, which can be enjoyed on foot or by using public transportation.
