Serra do Roncador and The Lost City

In the middle of Mato Grosso there’s a mountain range called the Serra do Roncador, shrouded in mystery. In 1925, a British explorer by the name of Percy Fawcett went there on a spiritual journey in search of the lost city of Atlantis. He was never seen again (well, unless you count the fictionalized, reimagined version of Fawcett, better known as Indiana Jones).
