Abstract

Outcrops of buried soils on lake-plains and glacial headlands along Lake Michigan's eastern shore suggest that periodic dune-building has occurred there after relatively long (>100 yr) periods of low sand supply. The AA. located, described, and radiocarbon dated 75 such buried soils that crop out in 32 coastal dune fields beside the lake. They assume that peaks in probability distributions of calibrated C 14 ages obtained from wood, charcoal, and other organic matter from buried A horizons approximate the time of soil burial by dunes. The modern dune landscape of the eastern shore is dominated by perched dunes formed during 150-yr lake highstands over the past 1500 yr
