Another important stratigraphical record of the Aare Valley is the scientific drill hole near Meikirch, north of Bern (Fig. 1). Here, fine-grained lake sediments are found below ca. 40 m of coarse-grained melt water deposits (Fig. 8). The lake sediments (ca. 70 m) are situated on top of glacial deposits (till). Detailed pollen analyses revealed evidence for three warm periods within the lake deposits, separated by two cold phases (Welten 1982, 1988). Based on luminescence dating and re-interpreting the original palynostratigraphy, Preusser et al. (2005) correlate these three warm phases, each of which represents interglacial environmental conditions, with Marine Isotope Stage (MIS) 7 (242–186 ka).
