It's time to say "The End~"

Hints:

Peary

Emerson and Scott 

Over the decades Peary was given the benefit of the doubt, but critics persisted in raising questions about his navigation and the distances he claimed to have covered. So the Navigation Foundation spent an additional 12 months of exhaustive examination of documents relating to Peary's polar expedition. The documents supported Peary's claims about the distances he covered. After also conducting an extensive computer analysis of photos taken by Peary at the pole, they concluded that Pierre and his companions did in fact reach the near vicinity of the North Pole on April 6th 1909. OK, today we're going to talk about exploration of the opposite end of the world, I assume you all read chapter three in our text and are now familiar with the names: Emerson and Scott.
