p.70: The Penninic domain in central and eastern Switzerland extends in several areas. One is located in an external position and comprises Lower Penninic flysch nappes and some klippen of Middle Penninic units overlain by rare remnants of Upper Penninic and Austroalpine units (from west to east: Giswilerstock, Stanserhorn, Buochserhorn, Mythen and Iberg klippen). However, most of the Penninic units of this region are located in a more internal position. They are confined to Graubünden and continue slightly south into the Italian valleys of San Giacomo and Malenco. External and internal units are also present east of the Rhine in the Vorarlberg (Austria) and converge eastward in the Allgäu (Germany) at the eastern end of the Helvetic domain.
