With all the colors pulled out in post processing this image could well be entitled " The Asgardian Rainbow Bridge Bifrost ".

The green airglow is very prevalent in the southwest deserts. The yellow cast on the right and left are both light pollution from distance cities.

The right portion of the image is due South with the left being North North East. I have no idea what the red glow on the left is. I didn't see it during the exposure and feel I was too far south for any Aurora to be seen during the recent solar activities. The light in the center was a vehicle of some sort driving around on the lake bed.
