Why Does the Grand Canyon Fill With Fog?

Video from Vox on YouTube.

On Thursday the 11th December 2014 the Grand Canyon entirely filled with fog. This rare spectacle only occurs a few times in a decade but to see such a huge space as the Grand Canyon filled with fog is an incredible sight and not one to be missed!

It is caused by a ‘temperature inversion’,   a natural phenomenon that will only happen when warm air gets trapped between two layers of cold air from the ground and the sky, the warm air holds the fog in place, or in the canyon.

As the fog is being held down it continues to form and spread until the entire body of this huge canyon is filled with nothing but fog. How grand is that?
