I want to know the answer to the following question:
What did the ascent of the Matterhorn mark?
All the background I'm provided with is that "While Mont Blanc was first climbed in 1786, most of the Alpine four-thousanders were climbed during the first half of the 19th century; the ascent of the Matterhorn in 1865 marked the end of the golden age of alpinism.". Is that enough to answer the question?
Answer: yes
