Prehistoric Copper Mining in Michigan
Author: John R. HalseyPublisher: U OF M MUSEUM ANTHRO ARCHAEOLOGY
ISBN: 0915703890
Category : Social Science
Languages : en
Pages : 351
Book Description
Isle Royale and the counties that line the northwest coast of Michigan's Upper Peninsula are called Copper Country because of the rich deposits of native copper there. In the nineteenth century, explorers and miners discovered evidence of prehistoric copper mining in this region. They used those "ancient diggings" as a guide to establishing their own, much larger mines, and in the process, destroyed the archaeological record left by the prehistoric miners. Using mining reports, newspaper accounts, personal letters, and other sources, this book reconstructs what these nineteenth-century discoverers found, how they interpreted the material remains of prehistoric activity, and what they did with the stone, wood, and copper tools they found at the prehistoric sites. "This volume represents an exhaustive compilation of the early written and published accounts of mines and mining in Michigan's Upper Peninsula. It will prove a valuable resource to current and future scholars. Through these early historic accounts of prospectors and miners, Halsey provides a vivid picture of what once could be seen." —John M. O'Shea, curator of Great Lakes Archaeology, University of Michigan Museum of Anthropological Archaeology
Minerals, Critical Minerals, and the U.S. Economy

Book Description
Minerals are part of virtually every product we use. Common examples include copper used in electrical wiring and titanium used to make airplane frames and paint pigments. The Information Age has ushered in a number of new mineral uses in a number of products including cell phones (e.g., tantalum) and liquid crystal displays (e.g., indium). For some minerals, such as the platinum group metals used to make cataytic converters in cars, there is no substitute. If the supply of any given mineral were to become restricted, consumers and sectors of the U.S. economy could be significantly affected. Risks to minerals supplies can include a sudden increase in demand or the possibility that natural ores can be exhausted or become too difficult to extract. Minerals are more vulnerable to supply restrictions if they come from a limited number of mines, mining companies, or nations. Baseline information on minerals is currently collected at the federal level, but no established methodology has existed to identify potentially critical minerals. This book develops such a methodology and suggests an enhanced federal initiative to collect and analyze the additional data needed to support this type of tool.
