Does anyone know an online source to illustrate glacial extent variability during last ice age, ca 120ky pb to 10ky pb? Most sources seem to concentrate only on the maximum, but apparently, there was quite a lot of variability. I'm mostly interested in Europe.

Thanks for any hints.

  • $\begingroup$ It is about the Scandinavian and Alpine glaciers during isotope stages 5, 4, 3 and 2, or from the Eemian warm phase to the begin of the Holocene. The alpine part is named the Würm glaciation, it's northern counterpart Weichselian. There were individual glacier retreats and spreads during this time, a lot is published. Alpine and Scandinavian glaciers aren't allways in time and correlating. $\endgroup$ – a_donda May 1 at 16:20

There's nothing I can find that gives figures. If you're interested in the extent of ice cover in particular areas it should be possible to create estimates based on temperature proxy data. The extent of ice cover is estimated using the equilibrium line altitude, altered for lower temperatures per the proxy estimates for the area. In this way it can also be possible to identify glacial morphology in now ice-free environments. This is the use of the technique I'm most familiar with, estimating the extent of historic glaciation in mountain ranges so that morphological features can be placed/studied in context.
