Oxygen-isotope and pollen analyses were carried out on late- and postglacial (Late Weichselian and Holo-cene) sediment samples of the raised bog. The 18O/16O-ratio results provide the first unequivocal proof for the Eastern Alps of the climatic deterioration of the Younger Dryas period. High NAP-values in the pollen diagram and a strong negative deviation in the oxygen-isotope curve characterize this period. The earlier Gerzensee fluctuation is also indicated by small changes in the oxygen-isotope curve. During the postglacial the Frosnitz climatic deterioration (6,000–6,500 B.P.) is evidenced as a fluctuation in the lake-level. The oxygen-isotope values indicate that the air temperature conditions remained unchanged at that time.
