We present a new regional calibration of the 10 Be production rate from two well‐dated surfaces in southern Norway: a rock avalanche with 14 C‐dated wood and a precisely dated Younger Dryas moraine. Calculated 10 Be production rates are 4.26 ± 0.13 and 4.65 ± 0.14 at g −1 a −1 for the Lal/Stone and Lifton scaling models, respectively. Our regional production rate for southern Norway is 5% lower than the canonical global 10 Be production rate with lower uncertainties. Our 10 Be production rate agrees with regional 10 Be production rates from north‐eastern North America and New Zealand. The 10 Be production rate estimate presented here can be used to improve the precision and accuracy of exposure‐dated ice‐marginal features, as well as other surfaces, in northern Europe.
