I want to know the answer to the following question:
What is often regarded as the most famous mountain in Switzerland?
All the background I'm provided with is that "In the southeast the long Engadin Valley, encompassing the St. Moritz area in canton of Graubünden, is also well known; the highest peak in the neighbouring Bernina Alps is Piz Bernina (4,049 m or 13,284 ft).". Is that enough to answer the question?
