Clouds Fill Grand Canyon in Rare Weather

A cloud inversion could be seen at Mather Point on the South Rim of the Grand Canyon. In some ways it looks like ocean tides coming in and going out. As word spread, rangers rushed to catch a glimpse during the 15 minutes of splendor. Inversions occur because cool, moist air is trapped under a warm, dry air, creating a layer of clouds that billow out of the Canyon.
