New pollen‐analytical investigations and two 14 C series indicate that, at the Bedrina on Mount Piottino (Tessin, Switzerland), the post‐Allerød NAP phase (Piottino oscillation) represents the well‐marked Younger Dryas at least for the most part. The late‐glacial part of the profile is re‐classified, and the term Piottino oscillation is rejected, as it is largely identical with the Younger Dryas. Individual 14 C dates from the transition between the Younger Dryas and the Preboreal should be considered critically. Considerable fluctuations in the 14 C level are supposed for this period.
