Fig. 8

Palaeogeographic sketch maps of northern Switzerland at time slices of decreasing age (age period indicated at lower left corner) with a drainage pattern lasting for some time, in million years (Ma). Dotted areas indicate potential deposition areas, red hatched lines represent drainage divides, thin red lines represent active faults, and black lines show major rivers. Blue areas in d–f show the potential maximum extension of piedmont glaciers during HDS and TDS deposition time (margins speculative)
