Klippe

For the style of coin, see Klippe (coin).

Schematic overview of a thrust system. The shaded material is called a nappe. The erosional hole is called a window or fenster. The klippe is the isolated block of the nappe overlying autochthonous material.

A klippe (German for cliff or crag) 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 autochthonous strata. Examples of klippes include:

• Chief Mountain, Montana
• Mount Yamnuska, Alberta
• The Rock of Gibraltar
