It looks other-worldly, but I can assure you, this is a real place. And this place is near the summit of Switzerland's Grimsel Pass. The green/gray tint to the water is from a suspension of teeny, tiny rocks and minerals that the glacial meltwater picked up on its way down the Alps. This cloudy water is sometimes called rock flour or glacial milk.
