Fog filled the Grand Canyon in a rare temperature inversion — when warm air acts as a lid and traps cool air and fog below it — on Friday, November 29th. Park ranger Erin Whittaker told The Daily Mail that inversions happen once or twice a year, but ones that affect the entire Grand Canyon only happen about every ten years. The Grand Canyon National Park has shared a number of breathtaking photos of the rare event on its Facebook page, and you can watch video footage captured by Steve Reeder on YouTube.
