Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Geology s Significant Sites and their Contributions to Geoheritage written by R. M. Clary and published by Geological Society of London. This book was released on 2024-07-23 with total page 471 pages. Available in PDF, EPUB and Kindle. Book excerpt: The contributions in this book explore several geologically significant sites and, in doing so, acknowledge and explore not just the geological exposures themselves, but also the people and issues that are fundamentally intertwined with the history of our science and its impact on our society. Through selective examples of outcrops and locales integral to the history of geology, we explore the evolution of modern geology, as well as the geodiversity and geoheritage of our planet. While the volume is far from comprehensive, the chapters contained herein detail a range for geoheritage value, scale of geoheritage sites and potential for geoheritage opportunities that will promote a broader, richer understanding of the complexity of the geoheritage of Earth. Importantly, many chapters offer a cautionary tale of sites almost lost to posterity and submit their take-away lessons for community mobilization towards geoheritage site protection.

Download or read book The Guide to Iowa s State Preserves written by Ruth Herzberg and published by University of Iowa Press. This book was released on 2001-12 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Iowa state preserves system was created in 1965; a decade later, thirty preserves had been dedicated, including “six native prairies, a native White Pine stand, the state's only Sphagnum bog, a Balsam Fir stand, some of the oldest exposed rock outcrops in the world, an ancient fort, a fen, several Indian mound groups and a historical cemetery.” This new guide to all ninety Iowa state preserves—biological, geological, archaeological, historical, and scenic—describes the state's most treasured prairies and forests, quartzite outcrops and ice caves, and Indian mounds and wetlands as well as such historic sites as Fort Atkinson and Montauk. Each entry includes two-color, progressively scaled maps giving the location of the preserve within the state, within its county, relative to a nearby town (with a recommended driving route), and on the local landscape (using USGS 7.5-minute topo maps). Also included are written directions (using 911 street names and signs); a description of the preserve's size, features, and history; a list of nearby or similar preserves, parks, natural areas, and other attractions; recommended readings; and contact information. (There are a few exceptions for privately owned or fragile preserves.) For travelers, a map in the introduction numbers all the preserves both geographically and alphabetically by name. Although the preserves system emphasizes preservation rather than recreation, some preserves do have formal trails; some allow hunting, horseback riding, and canoeing; a few have museums or nature centers. This comprehensive guide allows visitors to plan active and informative visits to sites that highlight Iowa's natural and cultural heritage.
