The timing of glacier advances in the northern European Alps based on surface exposure dating with cosmogenic 10Be, 26Al, 36Cl, and 21Ne
Exposure dating of boulder and bedrock surfaces with 10Be, 21Ne, 26Al, and 36Cl allows us to constrain periods of glacier expansion in the European Alps. The age of 155 ka from a boulder of Alpine lithology located in the Jura Mountains (Switzerland) provides a minimum age for pre-LGM (Last Glacial Maximum), more extensive Alpine glaciations. During the LGM, glaciers expanded onto the foreland after 30 ka. By 21.1 ± 0.9 ka deglaciation had begun, and the Rhône Glacier abandoned the E-mail: ivy@phys.ethz.ch.
