Earlier this week there was a huge amount of fog that rolled into The Grand Canyon, called an inversion. It’s where the fog/clouds completely fill the Grand Canyon below the rim: inverted from normal! It’s an effect when a high pressure system settled into the region and rapid cooling of the ground allowed a temperature inversion to form. The inversion trapped the enhanced moisture in the canyon which caused fog to warm overnight (moist cool air).
I’ve never seen this myself, but I have been up to the canyon in all kinds of bad weather. If you have a chance, I highly recommend a winter visit to The Grand Canyon! It’s so peaceful and you avoid the huge summertime crowds. Not only can you pick nearly any parking spot you want, but hotels are a lot less per-night and the views are spectacular with snow and clear skies.
