p.64: Escher (1988) grouped the Ruitor and Upper Stalden nappes with a “Pontis Slice” (south of Sierre, comprising mainly Triassic limestones) under the name of “Pontis Nappe”. It turns out that this “Pontis Slice” belongs to the Zone Houillère, so the term “Pontis Nappe” has to be abandoned (Sartori et al. 2006).
