Lacustrine sediments, 13 m thick, have been discovered under a Late Valdaian (Late Weichselian) moraine complex in a palaeokarst depression at Biržai, northern Lithuania. Wood fragments from silty layers in the basal part of the section were 14 C dated at 34,440 ± 1500 (Vs‐412) and 33,460 ± 1060 BP (LU‐1633). Pollen analytical results suggest that taiga landscapes similar to the present‐day environments in the Pechora Basin and eastern Urals occurred on the southern cryogenic grounds. Evidently, the ice sheet did not penetrate into the eastern Baltic region during the Middle Valdaian interval.
