Abstract
Radiocarbon dates of organic matter collected from ablation till or from the base of peat bogs in dead-ice deposits may postdate retreat of an active glacier terminus by hundreds or even thousands of years, and therefore provide only minimum estimates for the time of glacial maximum and the beginning of ice recession. Logs incorporated in Vashon till close to the drift border postdate recession of the Puget Lobe of the Cordilleran Ice Sheet by some 1400 years, and probably were buried when drift-mantled stagnant ice melted away, causing collapse of a superglacial forest.Keywords
