Short summary
Moraine is an awe-inspiring landscape in alpine areas and stores information on past climate. We measured the timing of moraine formation on the Ih Bogd Massif, southern Mongolia. Here, glaciers move synchronously as a response to changing climate; however, our glacier on the northern slope reached its maximum extent 3 millennia after the southern one. We ran a 2D ice surface model and found that the diachronous behavior of glaciers was real. Aspect also controls the mass of alpine glaciers.
