Glaciers left complex sedimentary successions in the Rhine trough and the southerly channel, comprising till, lake deposits and gravel (‘Engiwald-Formation’ and ‘Schmerlet-Formation’), was not eroded during ice meltdown. Partial erosion in Oberklettgau was caused by meltwater flowing through a small valley (Engi). Later, meltwater discharge shifted to the south, causing initial incision of the present course of the River Rhine.
