From Kråkenes Lake in western Norway there exist 118 accelerator mass spectrometry 14 C dates for the time interval 12 000–8000 14 C a BP that we earlier calibrated using the IntCal09 data set. These yielded the most accurate and precise ages available for the Younger Dryas boundaries and the Vedde and Saksunarvatn ashes. Here we present a new calibration using the recently published IntCal13 data set. All differences between the two sets of calibrated ages are within the ± 1σ error of the original IntCal09 results. The most significant differences are that the error for the Allerød/Younger Dryas boundary decreased, that this boundary became slightly older and that the length of the Younger Dryas increased slightly.
