p.62: The Rosswald Slice is present only east of the Rhône-Simplon Fault. In the Brig area (upper Valais), the Roignais-Versoyen Slice forms the reverse limb of a large anticline, whereas the Rosswald Slice forms the normal, thrusting limb. Both are present for the first 20 km east of the Rhône-Simplon Fault; only the Rosswald Slice continues further east. This slice contains only the upper formation of the “Valaisan Flysch”. It borders the Lepontic units to the north between the Visp – Brig area and the Valle Leventina. Its eastern termination is not clear. Probst (1980) splits it in several units and connects one of them with the Grava Nappe, through the large synform east of Airolo where it would have been partly eroded.
