Explain how a superimposed stream cutting through a mountain range forms
In the geologic past, the mountain or ridge, typically partially eroded, became buried beneath more recent rocks. The stream developed its course on the younger strata independent of the characteristics of the buried structure. As the younger rocks were eventually stripped away by erosion, the stream, still following its original course, was set down (superimposed) onto the rocks of the older, lower structure.
