Schematic section from upstream to downstream showing the modern surface topography as black dashed line, the thalweg of the modern Aare River (pale blue), the base of storeys 1 and 2, and the age of the Quaternary fill at the Brunnenbohrung drillsite (see Fig. 1 for location of drilling). The figure also shows the bedrock ridge beneath the city of Bern (grey area) and the inferred thalweg at some time before the MIS 8. The black rectangles indicate the uncertainty associated with the assignment of the corresponding depth. This uncertainty is derived from modelling
