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.

Available in PDF, EPUB and Kindle. Book excerpt: The rapid evolution of terrestrial ecosystems in the Devonian Period combined with climate change and many global events had a pronounced influence on sedimentation and biodiversity in various terrestrial and marine settings. This volume presents a number of case studies which cover the following topics land-sea transitional settings, the role of ecological-evolutionary subunits, the diversity and palaeoecology of reef building organisms and microfloras with respect to sedimentary processes and global events.

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.
