I want to know the answer to the following question:
What happened to the Alpine orogenic belt that gave it the steep vertical peak?
All the background I'm provided with is that "Peaks such as Mont Blanc, the Matterhorn, and high peaks in the Pennine Alps, the Briançonnais, and Hohe Tauern consist of layers of rock from the various orogenies including exposures of basement rock.". Is that enough to answer the question?
Answer: no
