Thanks to Mike from PBS Idea Channel and Jamin from PBS Game/Show for hanging out at the Grand Canyon with me!    / pbsideachannel      / pbsgameshow   Special thanks to Raymond Schillinger for great camera work! I was in Arizona recently for Phoenix Comic-Con, and had the amazing pleasure of seeing one of Earth's greatest natural wonders… the Grand Canyon. More than a mile deep, and several miles across, it just defies belief. But I couldn't help but think, the Colorado River down at the bottom isn't that big. How did it cut a canyon so massive? How old is the Grand Canyon? Here's its story http://www.nps.gov/grca/learn/nature/... Have an idea for an episode or an amazing science question you want answered?
