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

The writer has been engaged for several years on an investigation of the Pleistocene geology of North America and of the Vertebrata which have been discovered in the deposits of this epoch. At the outset the writer was convinced that, before just conclusions could be reached, it was necessary to know what fossil materials had been collected and under what geological and geographical conditions. He therefore made as thorough a search as possible of the literature for reports of discoveries of fossil vertebrates. In order to show the geographical distribution of the most important species that occur in considerable numbers, a series of maps has been prepared. Where the map of a State has become too crowded with numerals, a special map of that State for that species or genus has been prepared. There are maps of the edentates in Florida; mastodons of Indiana, of New York, of Ohio, of Michigan, of Florida; Elephas columbi in Florida; Elephas imperator in Florida; horses in Florida.
