Synopsis Iowa's Geological Past by : Wayne I. Anderson
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.

Synopsis Iowa's Archaeological Past by : Lynn M. Alex
Iowa has more than eighteen thousand archaeological sites, and research in the past few decades has transformed our knowledge of the state's human past. Drawing on the discoveries of many avocational and professional scientists, Lynn Alex describes Iowa's unique archaeological record as well as the challenges faced by today's researchers, armed with innovative techniques for the discovery and recovery of archaeological remains and increasingly refined frameworks for interpretation. The core of this book--which includes many historic photographs and maps as well as numerous new maps and drawings and a generous selection of color photos--explores in detail what archaeologists have learned from studying the state's material remains and their contexts. Examining the projectile points, potsherds, and patterns that make up the archaeological record, Alex describes the nature of the earliest settlements in Iowa, the development of farming cultures, the role of the environment and environmental change, geomorphology and the burial of sites, interaction among native societies, tribal affiliation of early historic groups, and the arrival and impact of Euro-Americans. In a final chapter, she examines the question of stewardship and the protection of Iowa's many archaeological resources.

Synopsis Iowa's Minerals by : Paul Garvin
In his carefully written text, geologist Paul Garvin has combined scientific facts about minerals with an appreciation of their history and beauty to produce a book that will appeal to scholars, collectors, and the general public. Garvin begins with a brief treatment of the origins of Iowa's minerals, moving from the oldest - with ages well in excess of a billion years - to those most recently formed. He describes the state's major mineral occurrences, providing detailed information for both specialists and amateurs, including how to obtain access to collecting sites. A history of Iowa's mineral industries complements Garvin's more technical information; this history is supplemented with stories about the Cardiff Giant (who now has his own web page), Ottumwa's Coal Palace, and the meteor falls of the late nineteenth century.

Synopsis The Emerald Horizon by : Cornelia F. Mutel
In The Emerald Horizon, Cornelia Mutel combines lyrical writing with meticulous scientific research to portray the environmental past, present, and future of Iowa. In doing so, she ties all of Iowa's natural features into one comprehensive whole. Since so much of the tallgrass state has been transformed into an agricultural landscape, Mutel focuses on understanding today’s natural environment by understanding yesterday’s changes. After summarizing the geological, archaeological, and ecological features that shaped Iowa’s modern landscape, she recreates the once-wild native communities that existed prior to Euroamerican settlement. Next she examines the dramatic changes that overtook native plant and animal communities as Iowa’s prairies, woodlands, and wetlands were transformed. Finally she presents realistic techniques for restoring native species and ecological processes as well as a broad variety of ways in which Iowans can reconnect with the natural world. Throughout, in addition to the many illustrations commissioned for this book, she offers careful scientific exposition, a strong sense of respect for the land, and encouragement to protect the future by learning from the past. The “emerald prairie” that “gleamed and shone to the horizon’s edge,” as botanist Thomas Macbride described it in 1895, has vanished. Cornelia Mutel’s passionate dedication to restoring this damaged landscape—and by extension the transformed landscape of the entire Corn Belt—invigorates her blend of natural history and human history. Believing that citizens who are knowledgeable about native species, communities, and ecological processes will better care for them, she gives us hope—and sound suggestions—for the future.

Synopsis How the Mountains Grew by : John Dvorak
The incredible story of the creation of a continent—our continent— from the acclaimed author of The Last Volcano and Mask of the Sun. The immense scale of geologic time is difficult to comprehend. Our lives—and the entirety of human history—are mere nanoseconds on this timescale. Yet we hugely influenced by the land we live on. From shales and fossil fuels, from lake beds to soil composition, from elevation to fault lines, what could be more relevant that the history of the ground beneath our feet? For most of modern history, geologists could say little more about why mountains grew than the obvious: there were forces acting inside the Earth that caused mountains to rise. But what were those forces? And why did they act in some places of the planet and not at others? When the theory of plate tectonics was proposed, our concept of how the Earth worked experienced a momentous shift. As the Andes continue to rise, the Atlantic Ocean steadily widens, and Honolulu creeps ever closer to Tokyo, this seemingly imperceptible creep of the Earth is revealed in the landscape all around us. But tectonics cannot—and do not—explain everything about the wonders of the North American landscape. What about the Black Hills? Or the walls of chalk that stand amongst the rolling hills of west Kansas? Or the fact that the states of Washington and Oregon are slowly rotating clockwise, and there a diamond mine in Arizona? It all points to the geologic secrets hidden inside the 2-billion-year-old-continental masses. A whopping ten times older than the rocky floors of the ocean, continents hold the clues to the long history of our planet. With a sprightly narrative that vividly brings this science to life, John Dvorak's How the Mountains Grew will fill readers with a newfound appreciation for the wonders of the land we live on.
