The channel of Oberklettgau, with a base at 340 m a.s.l., contains a complex sedimentary fill (Fig. 10). The sequence starts with glaciofluvial sediments (‘Hardau-Schotter’) that reach a thickness of up to 150 m. The gravel originates from the Lake Constance-Rhine Glacier, although the presence of ice in Klettgau is not documented for the time of gravel formation (Graf 2009a). An erosional trough was later incised into the gravel down to a level of 410 m a.s.l. In addition to the erosion along the valley axis, another channel originating from the south incised at the same time. This trough was later filled by glaciofluvial gravel (‘Geisslingen-Schotter’) ...
