The hill we climb - geomorphology of the planned route

I am a bit of an amateur geoscientist, which means landscapes talk to me, geology, geomorphology, ecology, agriculture and architecture interrupting each other all the time. I remember once sitting on a train to Denmark with a Terry Pratchett book that I was unable to read because the moraine landscape was so exciting. So here comes a short summary of the geomorphology along our route, which I am checking in preparation now.
Much of Denmark is composed of moraines, and Copenhagen is no exception. The trip starts on the island of Zealand, moving over hills left by the receding ice sheet, then over the island of Falster, passing south along the Guldborgsund, probably an ancient sub-glacial river valley) again to Lolland. Lolland will also be bumpy, with terrain dominated by wind-blown dunes of Baltic sand deposited in a long spit by the sea currents, ending at the harbour of Gedser.
After crossing the sea to Rostock, the landscape will be quite similar, we enter the Warnemünde estuary between the shore sand deposits, pass through the coastal dune zone, and leave the ferry slightly inland.
Here we continue south gradually uphill through the Mecklenburg Lake District, a landscape also formed by the ice sheet. Rivers under ice flowed in closed channels, like pipes, so they could also flow uphill. This means they carved the land into a valley system with many local low points, unlike classical river networks which have a continuous slope and thus do not support the formation of lakes. Here again, moraine deposits and drumlins will ensure plenty of up and down, winding our way through the Brandenburg Lakes and arriving in Berlin. Berlin is situated in an “Urstromtal”, a valley of an ancient glacial or sub-glacial river – clearly to be seen since the relatively small river Spree would not have formed such a wide valley.
South of Berlin we have a brief flat area, the outwash plain of the former ice sheet, then it goes uphill again through southern Brandenburg. Here some glacially-scoured rock formations are still to be found, but in general, the moraines continue, albeit from an earlier age. For us, this means river valleys are more prominent (more time for erosion to act) and therefore less climbing, but still lots of pretty lakes to see.
