Cosmogenic 10 Be dating of the Salpausselkä I Moraine in southwestern Finland
We determined in situ cosmogenic Be-10 ages for nine boulders sampled on the Salpausselka I (Ss I) Moraine. Previous dating of this moraine indicated that it formed during the Younger Dryas Stadial along the southern margin of the Scandinavian Ice Sheet in southern Finland. Our new exposure ages ran...

We determined in situ cosmogenic Be-10 ages for nine boulders sampled on the Salpausselka I (Ss I) Moraine. Previous dating of this moraine indicated that it formed during the Younger Dryas Stadial along the southern margin of the Scandinavian Ice Sheet in southern Finland. Our new exposure ages range from 10.9 +/- 1.0 to 13.5 +/- 1.2 Be-10 ka, with an error-weighted mean age of 12.4 +/- 0.7 Be-10 ka. Our results confirm four previous Be-10 ages obtained 40 km northeast of our sample location. The combined data (n = 13) indicate that retreat from the Ss I Moraine occurred at 12.5 +/- 0.7 Be-10 ka, in excellent agreement with an age of 12.1 ka for retreat from the Ss I Moraine based on varve chronologies.
