The Roggenstock-Mördergruebi Nappe consists of a pair of isolated klippes forming the highest unit of the Iberg Klippen in central Switzerland. It is in direct tectonic contact with the underlying Arosa Zone that in turn overthrusts Middle Penninic units and is therefore a testimony that Austroalpine cover nappes must have formerly extended as continuous thrust sheets westwards to the meridian of the Vierwaldstättersee. These klippes only expose Late Triassic to Early Jurassic sediments, which are correlated with the nappes of the Northern Calcareous Alps.
