ELI5 How did they find the exact location of the south pole in 1911. I know sailors used constellations to navigate but when they were in the south pole back then the sun never set.

Amundsens second in command was a naval navigator and the expedition spend three days taking observations of the exact possition of the sun and the moon from various possitions around the south pole to determine its exact possition. For Scott it was much easier as he could just see the big tent with the Norwegian flag marking the exact possition.
