description About

Where would you find the biggest dinosaur ever? The oldest glass in the world? A cave so precious it changed history? In the same place where you can fly forever, ski at 58 degrees Celsius (136 degrees Fahrenheit) and drink million-year-old water. The Sahara Desert provides unique challenges. Rock climbing in the extreme heat with geologist Matt Genge, Will Gadd discovers the ancient history of a lost superdesert. While Matt Genge and palaeontologist Matt Lamanna explore the eastern side of the Sahara, Gadd's journey takes him south, deep into the western side. Between them, they discover a world of deserts, savannas and oceans, and Gadd uses the extreme heat to try and reach the Holy Grail of paragliding — never-ending lift. He finds a new way to cross the oceans of sand and discovers what happened to the lost waters that once made this ultradry world a lush, beautiful land. The program offers an exclusive view of 12,000-year-old cave paintings previously seen by only handful of people in the world. We uncover previously unseen evidence of a massive meteorite strike. It is now estimated that the rock that slammed into the Sahara was half a mile wide.
