Book Description
Iowa's rock record is the product of more than three billion years of geological processes. The state endured multiple episodes of continental glaciation during the Pleistocene Ice Age, and the last glacier retreated from Iowa a mere (geologically speaking) twelve thousand years ago. Prior to that, dozens of seas came and went, leaving behind limestone beds with rich fossil records. Lush coal swamps, salty lagoons, briny basins, enormous alluvial plains, ancient rifts, and rugged Precambrian mountain belts all left their mark. In "Iowa's Geological Past, " Wayne Anderson gives us an up-to-date and well-informed account of the state's vast geological history from the Precambrian through the end of the Great Ice Age. Anderson takes us on a journey backward into time to explore Iowa's rock-and-sediment record. In the distant past, prehistoric Iowa was covered with shallow seas; coniferous forests flourished in areas beyond the continental glaciers; and a wide variety of animals existed, including mastodon, mammoth, musk ox, giant beaver, camel, and giant sloth. The presence of humans can be traced back to the Paleo-Indian interval, 9,500 to 7,500 years ago. Iowa in Paleozoic time experienced numerous coastal plain and shallow marine environments. Early in the Precambrian, Iowa was part of ancient mountain belts in which granite and other rocks were formed well below the earth's surface. The hills and valleys of the Hawkeye State are not everlasting when viewed from the perspective of geologic time. Overall, Iowa's geologic column records an extraordinary transformation over more than three billion years. Wayne Anderson's profusely illustrated volume provides a comprehensive and accessible survey of the state's remarkable geological past.

Book Description
Archaeologists across the Midwest have pooled their data and perspectives to produce this indispensable volume on the Native cultures of the Late Woodland period (approximately A.D. 300?1000). Sandwiched between the well-known Hopewellian and Mississippian eras of monumental mound construction, theøLate Woodland period has received insufficient attention from archaeologists, who have frequently characterized it as consisting of relatively drab artifact assemblages. The close connections between this period and subsequent Mississippian and Fort Ancient societies, however, make it especially valuable for cross-cultural researchers. Understanding the cultural processes at work during the Late Woodland period will yield important clues about the long-term forces that stimulate and enhance social inequality. Late Woodland Societies is notable for its comprehensive geographic coverage; exhaustive presentation and discussion of sites, artifacts, and prehistoric cultural practices; and critical summaries of interpretive perspectives and trends in scholarship. The vast amount of information and theory brought together, examined, and synthesized by the contributors produces a detailed, coherent, and systematic picture of Late Woodland lifestyles across the Midwest. The Late Woodland can now be seen as a dynamic time in its own right and instrumental to the emergence of complex late prehistoric cultures across the Midwest and Southeast.
