Generalised map of the Bündnerschiefer and Flysch formations of the current mapping campaign on the Schesaplana, Sulzfluh, Schiers and Serneus sheets of the Swiss Geological Atlas. The map by Nänny (1948) was a useful basis, but had to be modified in several places. Some elements of the results of Steinmann (1994) and Weh and Froitzhein (2001) are integrated. Note the mapped unconformity (in green) between Cretaceous Bündnerschiefer and Cenozoic flysch formations and the variable order of thrusts along the eastern margin of the window
