I want to know the answer to the following question:
Where did the mountains undergo serve erosion?
All the background I'm provided with is that "In the Miocene Epoch the mountains underwent severe erosion because of glaciation, which was noted in the mid-19th century by naturalist Louis Agassiz who presented a paper proclaiming the Alps were covered in ice at various intervals—a theory he formed when studying rocks near his Neuchâtel home which he believed originated to the west in the Bernese Oberland.". Is that enough to answer the question?
Answer: yes
