Variable responses of western US glaciers during the last deglaciation
Cosmogenic Be-10 exposure ages from moraines in the Wallowa Mountains, Oregon, identify two maximal late Pleistocene glaciations at 21.1 +/- 0.4 ka and 17.0 +/- 0.3 ka and a minor glacial event at 10.2 +/- 0.6 ka. Our new high-resolution chronology, integrated with other well-dated glacial records f...
