Originally I planned to go to Red Rock Crossing at Sedona to take
picture of Cathedral Rock. But it was rainy and cloudy, and
therefore I decided to leave. On my way back I stopped by an
overlook and saw this rainbow. If you look at the rainbow closely,
you can see that here are some diagonal gray lines in front of the
rainbow, meaning that it was still raining at that moment. A
minute later the rainbow disappeared.
