Mount Roraima, Brazil/Guyana/Venezuela!

Mount Roraima is an amazing geologic wonder located primarily in Venezuela . Roraima is a spectacular example of a tepui, a flat tabletop like mountain made of Precambrian quartz arenite (pure quartz) sandstone that rises 9,000 ft into the air. This juxtaposition of low-lying rainforests and the elevated tepui produces the world’s tallest waterfall, Angel Falls. Underlain by the ancient Guiana Shield, Mount Roraima is one of the oldest geological formations on earth, estimated to be approximately 2 billion years old.
