Strandplains of shore-parallel beach ridges bordering the Great Lakes are valuable for reconstructing histories of climate-related lake-level fluctuations. The resolution and imprecision of radiocarbon chronologies can be improved with AMS C 14 dates of roots and rhizomes of plant species associated with the formation and growth of the sand -dune caps of beach ridges. An AMS radiocarbon chronology of beach-ridge formation in northern Lake Michigan shows that information about variation in the frequency of ridge formation is important for paleoclimatic interpretation
