Paleo-channel and Beringen maximum extent modified after Graf (2009)

Schematic illustration of the inferred ice-margin position during the Beringen Glaciation (~ MIS6) with emphasis on evidence for a Late Beringen re-advance (frontal position IV) in the Glatt valley and surrounding areas at the end of MIS6 (~ 150–130 ka). Together with the most extensive Beringen Glaciation advances (frontal positions II and III) and a potential early advance into the Middle Glatt valley (frontal positions I, Hagenholz advance) a total of up to four glaciation phases can be distinguished.
