This trough was later filled by glaciofluvial gravel (‘Geisslingen-Schotter’), with deposition in the eastern part originating from the Lake Constance-Rhine glacier, and in the southern channel from the Walensee branch of the Rhine glacier. The maximum ice extent during this phase (Hagenholz advance) was about 25 km SE of Klettgau, close to the present airport of Zurich (Graf 2009a).
