I want to know the answer to the following question:
When were the last of the six great north faces of the Alps climbed?
All the background I'm provided with is that "Edward Whymper reached the top of the Matterhorn in 1865 (after seven attempts), and in 1938 the last of the six great north faces of the Alps was climbed with the first ascent of the Eiger Nordwand (north face of the Eiger).". Is that enough to answer the question?
Answer: yes
