A total cloud inversion on Thursday obscured visitors' view of the Grand Canyon. It's a phenomenon that happens every few years when warm air traps a layer of cold air below the canyon walls. It could take a few days before the canyon clears. The view above is from Mather Point on the south rim. Grand Canyon National Park posted a one-minute time lapse of the clouds flowing like tides on Facebook.
