At the construction sites of the A4-highway tunnel through Uetliberg near Zurich, more than 140 buried subfossil pine stumps have been excavated. The trees were buried during their lifetime by loamy alluvia washed down from the upper part of the slopes. The stumps have remained well preserved for more than 13,000 years BP. The wood samples (cross sections of the trunks) were analyzed dendrochronologically. The radiocarbon method was used to determine their age. Three new floating chronologies were built and they were linked with chronologies from Daettnau produced by Kaiser (1993), termed DAEALCH_1 and DAEALCH_2. The newly built chronologies cover the main parts of the Allerød (ALLCH_A and ALLCH_D) and also a part of the Younger Dryas (YD_A). Student’s t-values, percentages of parallel variation ('Gleichlaeufigkeit') and radiocarbon wiggle matching (¹⁴C age determinations on a decadal scale) support the validity of the resulting chronology.
