p.286: Iberig

The deposits at Iberig, a hill in the lower Aare Valley near Würenlingen, are situated at an elevation between 440–470 m a.s.l. (Fig. 1). Topographically this level is significantly lower than the one at Irchel, and therefore the deposits are considered to be part of ‘Tiefere Deckenschotter’. Several drill holes revealed the presence of three glaciofluvial and two glacial units at this site (Fig. 4). (...)

This channel system is cut into older deposits and indicates that ‘Tiefere Deckenschotter’ reflect at least four phases of glaciofluvial deposition, for two of which the presence of glaciers in the Swiss lowlands is clearly documented by the presence of till.
