This paper is about deglaciation history in two areas of southern Norway. By dating rock surfaces we can estimate a minimum ice sheet thickness of 1476 m a.s.l. and a timing of deglaciation around 13 000 years ago in the western study area. In the eastern study area the deglaciation history is complex as the bedrock age most likely has inheritance from earlier ice-free periods. Comparing both study areas demonstrates the complex dynamics of the deglaciation in different areas in southern Norway.

Deposits related to the last advance of Reuss Glacier are dated using a luminescence methodology. An age of 25 ka for sediment directly overlying the lodgement till corresponds with existing age constraints for the last maximal position of glaciers. Luminescence dating further implies an earlier advance of Reuss Glacier into the lowlands during Marine Isotope Stage 4. The data are discussed regarding potential changes in the source of precipitation during the Late Pleistocene.
