Sampling and measurement was done in 2013. Snow corrected ages are shown for comparison. Erosion corrected ages are used in the discussion
^aShielding correction includes the topographic shielding due to surrounding landscape and the dip of the sampled surface. Additionally for the bedrock samples a snow shielding correction factor of 0.8313 was multiplied with the shielding correction (see text)
^b AMS measurement errors are at the 1σ level
^c Bedrock samples. All others are from boulders
