"Uncovers a centuries-long story of obsession that often included murder, gun fights, deadly accidents, overnight fortunes and even cannibalism. . . Neligh is a practiced writer whose style mixes history and modern realities seamlessly." -Colorado Country Life Gold! brings together the story of this metal’s glittering legacy in the Centennial State and the madness, murder, and mayhem that came along with it. The book examines the rich history of the miners and treasure hunters who came to face danger and hardships in the unforgiving Rocky Mountains. This story is unique in that it takes a look at the phenomenon of gold, the treasure hunters, both modern and historic, and brings them to life in a detailed and sharp narrative. Author Ian Neligh spent a year meeting with experts and enthusiasts, hearing their stories and trying to understand why it is they continue to do what they do—often in the face of extreme hardship. Modern-day gold miners profiled include Al Mosch, Bill Chapman, Ken Reid, and Chad Watkins. Gold! is the story of an unusual subculture on the rise in the mountains of Colorado fueled by a delicate balance of hope, greed, and loss. It tells the story of men mostly forgotten by the world as they go in endless pursuit of an impossible fortune. It follows miners working their small, dangerous gold claims in mines over a hundred years old, to modern-day prospectors trying to strike it rich and counterbalance the weight of a struggling economy. The book also examines if those who spend their lives in search of riches—ever actually strike it rich. This book will appeal to both history buffs as well as fans of modern-day reality shows like Gold Rush.

"This book fills an important gap with a clear and comprehensive explanation of how rivers are changed by human activity. The book also includes a generous selection of striking historical and contemporary photographs, maps, and diagrams that provide a fresh perspective on the extent to which the rivers of the Colorado Front Range have undergone change during the last two centuries."--BOOK JACKET.

A survey of the feasibility of aircraft- and satellite-based methods for revealing environmental-geological problems. Throughout, a balanced ratio between explanations on the methodological/technical side and presentations of case studies is maintained. The comparison of case studies from North America and Germany shows how the respective territorial conditions lead to distinct methodological approaches. Equally, the considerable dissimilarities in population density and in distances between waste disposal areas, settlements, and areas of protected groundwater necessitate a "diversified methods" approach.

This illustrated handbook describes a broad spectrum of methods in the fields of remote sensing, geophysics, geology, hydrogeology, geochemistry, and microbiology designed to investigate landfill, mining and industrial sites. The descriptions provide information about the principle of the methods, applications and fundamentals. This handbook also deals with the stepwise procedure for investigating sites and common problems faced in efficient implementation of field operations.

Over the past five hundred years, North Americans have increasingly turned to mining to produce many of their basic social and cultural objects. From cell phones to cars and roadways, metal pots to wall tile and even talcum powder, mineral-intensive products have become central to modern North American life. As this process has unfolded, mining has also indelibly shaped the natural world and North Americans’ relationship with it. Mountains have been honeycombed, rivers poisoned, and forests leveled. The effects of these environmental transformations have fallen unevenly across North American societies. Mining North America examines these developments. Drawing on the work of scholars from Mexico, the United States, and Canada, this book explores how mining has shaped North America over the last half millennium. It covers an array of minerals and geographies while seeking to draw mining into the core debates that animate North American environmental history generally. Taken together, the authors' contributions make a powerful case for the centrality of mining in forging North American environments and societies.
