Klippe
. The erosional hole is called a window or fenster. The klippe is the isolated block of the nappe overlying autochthonous material.
A klippe is a geological feature of thrust fault terrains. The klippe is the remnant portion of a nappe after erosion has removed connecting portions of the nappe. This process results in an outlier of exotic, often nearly horizontally translated strata overlying strata. Examples of klippes include:
Klippes may also be found in the Pre-Alps of Switzerland and some of the isolated mountains in Assynt, Sutherland, in NW Scotland.
