p.40: The Wildhorn Nappe Complex consists of three superposed nappes: the Diablerets Nappe, present only in the southwest, at the base of the complex, is linked by a tight syncline to the Mont Gond Nappe, which is also outcropping mainly in the southwestern part of the complex. The highest Sublage Nappe forms the main body of the complex; it overlies the thin Jägerchrüz Nappe north of Sierre and the Gellihorn Nappe further northeast (see § 4.1.3).
