p.187: Conglomerate or breccia with partly coarse-grained sandy matrix composed of marlstone (Stad Formation). Pebbles of the Cretaceous (predominantly Betlis Limestone, occasionally Helvetischer Kieselkalk) and Middle Eocene strata (Klimsenhorn Formation) originate from the Axen nappe of the Jochpass region near Engelberg (Canton Obwalden) (Schumacher 1948).
