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

As the importance and dependence of specific mineral commodities increase, so does concern about their supply. The United States is currently 100 percent reliant on foreign sources for 20 mineral commodities and imports the majority of its supply of more than 50 mineral commodities. Mineral commodities that have important uses and face potential supply disruption are critical to American economic and national security. However, a mineral commodity's importance and the nature of its supply chain can change with time; a mineral commodity that may not have been considered critical 25 years ago may be critical today, and one considered critical today may not be so in the future. The U.S. Geological Survey has produced this volume to describe a select group of mineral commodities currently critical to our economy and security. For each mineral commodity covered, the authors provide a comprehensive look at (1) the commodity's use; (2) the geology and global distribution of the mineral deposit types that account for the present and possible future supply of the commodity; (3) the current status of production, reserves, and resources in the United States and globally; and (4) environmental considerations related to the commodity's production from different types of mineral deposits. The volume describes U.S. critical mineral resources in a global context, for no country can be self-sufficient for all its mineral commodity needs, and the United States will always rely on global mineral commodity supply chains. This volume provides the scientific understanding of critical mineral resources required for informed decisionmaking by those responsible for ensuring that the United States has a secure and sustainable supply of mineral commodities.

A comprehensive & illuminating history of this little-understood, but surprisingly significant scientific activity. Quite rigorous & systematic in its methodology, the book explores the development of the radar astronomy specialty in the larger community of scientists. More than just discussing the development of this field, however, the author uses planetary radar astronomy as a vehicle for understanding larger issues relative to the planning & execution of "big science" by the Fed. government. Sources, interviews, technical essay, abbreviations, & index.
