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

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.

"Over the course of his 43-year career, James C. Knox conducted seminal research on the geomorphology of the Driftless Area of southwestern Wisconsin. His research covered wide-ranging topics such as long-term land-scape evolution in the Driftless Area; responses of floods to climate change since the last glaciation; processes and timing of floodplain sediment deposition on both small streams and on the Mississippi River; impacts of European settlement on the landscape; and responses of stream systems to land-use changes. This volume presents the state of knowledge of the physical geography and geology of this unglaciated region in the otherwise-glaciated Midwest with contributions written by Knox prior to his passing in 2012 and by a number of his former colleagues and graduate students"--

This book discusses the karst and pseudokarst of the Upper Midwest, USA, consisting of the states of Minnesota, Wisconsin, Iowa, and Illinois—the first regional synthesis in 40 years. Starting with an overview of the regional geology of what is largely glaciated fluviokarst and paleokarst developed on Paleozoic carbonates, but including other lithologies such as the St. Peter Sandstone and the Ft. Dodge Gypsum, the caves, springs, sinkholes, and karst hydrogeology of each state are described. Special attention is devoted to the region’s longest caves: Coldwater Cave, Mystery Cave, and the Minnesota Cave Preserve caves. Application of tools such as data loggers and LiDAR, with new conceptual models such as hypogenic speleogenesis, has been transformative here. Special topics include lead and zinc mining in the Driftless Area, vertebrate and invertebrate cave fauna near the Laurentide ice limit, the impact and policies of nutrient and herbicide intensive modern agriculture on karst, and paleoclimate studies. The discovery, exploration, institutional history of caving organizations, and show caves of the Upper Midwest, from the year 1700 onwards, are brought up to date. The top 10 historical paradigms of cave and karst science in the Midwest are reviewed. Perspectives on paleontology, archeology, and Native American rock art are included.
