Rhône-Simplon line
The Rhone-Simplon line is a large geologic faultzone in the Swiss Alps.
The line runs from the Ossola valley over the Simplon Pass and then follows the Rhône valley in an east-west direction. Somewhere south of Sion it goes over smoothly into the Penninic thrustfront.
Geologically speaking, the line serves as a huge dextral strike-slip fault. The northeastern block is moving up as well. Geologists see the line as an expression of the continued NNW movement of the Apulian plate into the European plate.
