Originally published in 1848 as the first major work in the nascent discipline as well as the first publication of the newly established Smithsonian Institution, Ancient Monuments of the Mississippi Valley remains today not only a key document in the history of American archaeology but also the primary source of information on hundreds of mounds and earthworks in the eastern United States, most of which have now vanished. Despite adhering to the popular assumption that the moundbuilders could not have been the ancestors of the supposedly savage Native American groups still living in the region, the authors set high standards for their time. Their work provides insight into some of the conceptual, methodological, and substantive issues that archaeologists still confront. Long out of print, this 150th anniversary edition includes David J. Meltzer's lively introduction, which describes the controversies surrounding the book’s original publication, from a bitter, decades-long feud between Squier and Davis to widespread debates about the links between race, religion, and human origins. Complete with a new index and bibliography, and illustrated with the original maps, plates, and engravings, Ancient Monuments of the Mississippi Valley provides a new generation with a first-hand view of this pioneer era in American 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.
