That's incredible!

I’ve seen these in the big mountains too. There are a few different types of these refraction phenomenon’s; Parhelia or sun dogs, 22 degree halo, 46 degree halo, circumzenithal arc, parry arc, upper tangent arc and sun pillar. You can also get the same effect by squeegeeing your third eye. I have no idea what this refraction is called. Here is a photo of one that I saw at Hatcher Pass, AK in the winter.

"Diffraction of sunlight by minute cloud droplets is responsible for the lovely pastel hues. Because the droplets are so tiny (1/10 to 1/1000 the size of raindrops), light waves that interact with them aren't refracted nearly as much as they're deflected -- in all directions. Iridescence or irisation is generally observed in clouds that have formed relatively recently since then their droplets are more likely to be quite small and of more uniform size. Iridescent clouds are found within about 20 degrees of the Sun, so make sure to protect your eyes whenever looking for them."

Obviously, with the extreme altitude, the diffraction is probably due to an alignment of hexagonal ice crystals. Same effect.

Here is a really neat video on a related note
