Journey to one of Earth's few landforms visible from space, a World Heritage site and one of America's most popular National Parks - with over 5 million visitors a year. For scientists it is a place of baffling mysteries. National Geographic joins a rare scientific odyssey down the Grand Canyon's entire 277-mile length - through some of the most treacherous rapids on the planet - to try to unlock the mysteries of this great unknown. From the river still cutting through two-billion-year-old stone to the creatures roaming its incomparable back-country, the Grand Canyon still has secrets to tell.
