Improved dating methods have increased our ability to more precisely determine the timing and durations of glaciations. Utilizing glacial and loess deposits, we have compared glaciations that occurred in North and South America in order to determine if events are synchronous or not, to explore forcing mechanisms, and to compare glaciations with cold periods of the Marine Oxygen Isotope stages and the loess/paleosol records of China. Stratigraphic sections containing a variety of glacial deposits, some with interbedded volcanics, as well as loess deposits, were used in reconstructing the glacial history. The Late Pleistocene (Brunhes Chron) Last Glacial Maximum is recognized in  mountain and continental areas of North America but only in the mountains of South America. Commonly our comparisons indicate roughly synchronous glaciations on the two continents, whereas other glaciations are more elusive and difficult to compare. Although our comparisons are at low resolutions, the results suggest that Milankovitch forcing is most likely the dominant trigger for hemispheric glaciation modified by local factors.
Nat Rutter's research centers on paleoclimates and climate change during the Quaternary period. Special emphasis has been placed on loess-paleosol sequences in North Central China, Siberia and the Russian Plain. A major effort by his students has been on the Quaternary stratigraphy and environments of western and northern Canada. Other...

Editorial Reviews

From the reviews:"The authors succeeded in presenting an up-to-date state-of-the-art summary of the (extra-tropical) glaciations of South and North America. . The text is clear and easy to understand, the figures explain the basic items. . For all who are involved in Quaternary research in the Americas (in extra-tropical regions) it presents a state-of-the-art report, new research results, and emerging topics of hemispheric glacial correlations, since during the recent years improved dating methods have increased the ability to more precisely determine the timing and durations of glaciations." (Klaus Heine, Zeitschrift für Geomorphologie, Vol. 57 (4), 2013)
