Yesterday morning as we were heading south from our northern California visit, we saw this amazing cloud at the top of Mount Shasta. The sun was rising behind the mountain and the "cloud" was likely snow or ice crystals being whipped about the summit by strong winds. The swirling winds give the "cloud" a somewhat biomorphic appearance. The angle of the sun relative to the cloud created a rainbow effect. I didn't push saturation or vibrance in the image but I did expose for the cloud which made the mountain a little darker than it was in person. The cloud and rainbow effect was short lived but I've never seen anything quite like it and felt fortunate to be at the right place at the right time with the camera. It's not so much a great photograph as a very interesting phenomenon - had to share it.
