The Channeled Scablands of the Pacific Northwest hide an astonishing secret. Evidence of a massive flood that shaped the entire region lies just beneath its landscape. But it can only be seen with cutting edge LIDAR technology. Join Joe as he learns how scientists are using lasers to reveal details that may help us predict the paths of potential megafloods of the future.

Hosted by Joe Hanson from Be Smart, Overview uses stunning 4k drone footage to reveal the natural and human made marvels shaping our planet–from a 10,000-foot view–literally.
