p.285: Early Pleistocene (‘Deckenschotter glaciations’) The oldest Pleistocene deposits of northern Switzerland, usually referred to as ‘Deckenschotter’, mainly consist of (glaciofluvial) gravel, with some intercalated glacial sediments (till) and overbank deposits. The present distribution of these deposits is between the easternmost part of the Jura Mountains (‘Lägern‘), the River Aare, the River Rhine, and Lake Constance (Graf 1993). Lesser remnants of these strata are found to the east of Lake Constance (Graf 2009b) as well as in some parts of northern Central Switzerland (Fig. 2). The remains of ‘Deckenschotter’ are typically found forming the top of table mountains. The term ‘Deckenschotter’ was originally introduced by Penck & Brückner (1901/09) for deposits from Bavaria, and refers to past gravel accumulation on a broad-spread plain at the front of Alpine lowland glaciation. The ‘Deckenschotter’ of northern Switzerland, however, do not represent sheet-like gravel plain deposition on top of Molasse bedrock, but are the fills of several broad channels that are representing the past major drainage network of the northern Swiss Midlands (Graf 1993). ‘Deckenschotter’ deposits are found at two distinct topographic levels, and are therefore subdivided into a higher (‘Höhere Deckenschotter’) and a lower (‘Tiefere Deckenschotter’) unit. Both units represent depositional complexes. The channels of the lower (younger) unit have the same major drainage direction as the higher (older) unit, but are more deeply incised into Jurassic limestone and Molasse bedrock.
