“In anatomy, heterochromia refers to a difference in coloration, usually of the iris (but also of hair or skin).

“Lofoten Glow”. I was desperately searching a good sunrise spot this particular morning. Normally Storvatnet Lake is completely covered in snow, so you can only imagine my surprise when I saw these crazy ice formations almost being shot out of the frozen lake.
