ID: somewhere under the rainbow

From the National Geographic, this rare Idaho "rainbow":


Sean got to see this live and in person. I suppose that you could be all prosaic about this being just a circumhorizontal arc caused by light passing through wispy, high-altitude cirrus clouds, which occurs only when the sun is very high in the sky and the hexagonal ice crystals that make up the cirrus clouds are shaped like thick plates with their faces parallel to the ground.

Or, you could take it as a celestial high-five to the folks back home fighting Idaho's latest anti-gay ballot measure.
