The youngest gravel unit is topped by basal till (‘Rotachewald-Grundmoräne), correlated with the Last Glaciation of the area (Schlüchter 1989a, b). The weathered gravel above the basin deposits are, based on the petrography, interpreted to result from a glacier advance beyond the margin of the Alps. The age of this advance has to be younger than Eemian but must be significantly older than the last advance, as it shows intense weathering. Luminescence dating of sandy sediments on top of the interglacial deposits implies that the weathered gravel unit was probably deposited during an early phase of the last glacial cycle (Preusser & Schlüchter 2004).
