Several temporal and event classifications are used for the Quaternary glacial and interglacial record in the Great Lakes region of North America. Although based on contrasting principles, the classifications, as practiced, are similar to one another in most respects and they differ little from the classification proposed by Chamberlin a century ago. All are based on stratigraphic units having time-transgressive...
Despite the importance of dating glacial sequences, little evidence has been available to highlight the stratigraphic issues associated with the interpretation of age analysis. A compilation of radiocarbon data from the Miami sublobe of the Laurentide ice sheet, provides a large enough data set (more than 133 dates) to identify at least two sources of error: sample and unit variability, and transportation...
