A pollen diagram of a calcareous travertine bed near Kirf (West Germany) shows a tripartition of the Allerød chronozone. In northwestern and central‐European diagrams this is not an uncommon phenom‐enon. Arguments supporting a deduced climatic oscillation may also be derived from the average ice recession in southern Sweden, the Coleoptera assemblages in northwestern England, the isotope 18 0/ 16 O curve from the Gerzensee in Switzerland, and the Camp Century Ice Core in Greenland. The included sandy Laachcr See ash may suggest explosive volcanism again to be somehow related to inferred climatic changes.
