In search of terrestrial limits man has tried to tread on all the “finisterres”: the sea beds, the extreme coasts, the poles, the heart of jungles and deserts, the Moon and outer space. Also mountain summits, even –sometimes with more fervor– the apparently unaccessable and, naturally, the highest. But prior to this, all of them had to be documented and the altitude of their peaks reliably measured. The first exploration in search of the highest mountain was thus strictly geographic and its location moved from mountain range to mountain range until very belatedly settling on Mount Everest, in the Himalaya. This was followed by Alpine exploration to find the route to the top. This is a beautiful story of landscapes, science, perserverance and braveness.
