We drove into the Grand Teton National Park on last week. There was late afternoon storm building over the Teton range. I captured a wall cloud with heavy rain and crepuscular rays over the mountain – 7-16-12 – one of my favorites of the project! About 30 minutes later, the storm moved out over the Snake River (pictured above) and towards Yellowstone. It was beautiful moving away from us. Click on the image to enlarge.
