Taking advantage of new technological advances in Quaternary geology and geomorphology, this volume showcases new developments in glacial geology. Honoring the legacy of Frank Leverett and F.B. Taylor's 1915 USGS monograph of the region, this book includes 12 chapters that cover diverse topics ranging from hydrogeology, near-surface geophysics, geotectonics, and vertebrate paleontology to glacial geomorphology and glacial history. Several papers make use of detailed but nuanced shaded relief maps of digital elevation models of LiDAR data; these advances are brought into historical perspective by visiting the history of geologic mapping of Michigan. Looking forward, interpretations of the shaded relief maps evoke novel processes, such as regional evolution of subglacial and supraglacial drainage systems of receding glacial margins. The volume also includes assessment of chronological issues in light of greater accuracy and precision of radiocarbon dating of plant fossils using accelerator mass spectrometry versus older techniques.

The book presents an up-to-date, detailed overview of the Quaternary glaciations all over the world, not only with regard to stratigraphy but also with regard to major glacial landforms and the extent of the respective ice sheets. The locations of key sites are included. The information is presented in digital, uniformly prepared maps which can be used in a Geographical Information System (GIS) such as ArcView or ArcGIS. The accompanying text supplies the information on how the data were obtained (geomorphology, geological mapping, air photograph evaluation, satellite imagery), how the features were dated (14C, TL, relative stratigraphy) and how reliable they are supposed to be. All references to the underlying basic publications are included. Where controversial interpretations are possible e.g. in Siberia or Tibet, this is pointed out. As a result, the information on Quaternary glaciations worldwide will be much improved and supplied in a uniform digital format. The information on the glacial limits is compiled in digital form by the coordinators of the project, and is available for download at: http://booksite.elsevier.com/9780444534477/ Completely updated detailed coverage of worldwide Quaternary glaciations Information in digital, uniformly prepared maps which can be used in a GIS such as ArcView or ArcGis Step-by-step guideline how to open and use ArcGis files Possibility to convert the shapefiles into GoogleEarth kmz-files Availability of chronological controls

Corn State. Prairie State. Garden of the West. Each of these nicknames for the State of Illinois has a truth to tell. But not the whole truth. The world-class lens of Willard Clay reveals secrets about his home state that justify another nickname: the State of Hidden Delights. For Wild & Scenic Illinois, Willard Clay has crisscrossed the state's byways and trails in his search for the rare, the beautiful, the seldom-seen jewels of the Illinois landscape. Wild & Scenic Illinois is the most discerning and the most rhapsodic portrait of the natural face of Illinois ever published. Clay has gleaned images from every province in Illinois, ranging across all seasons, times, and natural subjects. His photographs are systematically grouped into Illinois's various landscape provinces, explored in an informative introduction and extended captions by naturalist Robert Hutchinson. In the photographer's introduction, Willard Clay shares his tips for tackling the technical challenges of shooting the landscape of Illinois.
