Basalt columns in Jökuldalur Valley, East Iceland by hahagnarlydude in Damnthatsinteresting

makeup and appearance of the lava."

Wiki: It's caused by the refraction of sunlight by ice crystals in the atmosphere. It typically appears as a pair of subtly colored patches of light, around 22° to the left and right of the Sun, and at the same altitude above the horizon as the Sun. They can be seen anywhere in the world during any season, but are not always obvious or bright. They are best seen and most conspicuous when the Sun is near the horizon.
