#EdgeOfTheUnknown premieres TONIGHT at 9:30/8:30c on National Geographic Channel! 🧗 I think it’s appropriate that @alexhonnold opens the series. In his episode we take a look at the story behind the story of Free Solo and one of the massive big wall free solos he climbed in Morocco in preparation for El Capitan. Hope you enjoy it! The series lands on @disneyplus on Sept 7th.
