There’s a lake in Camargue, France that has turned blood-red as a result of high salt concentration. Blood-red! It’s shocking to my senses just in a photograph, so I can’t imagine what it would be like to see in person. My reaction fluctuates between fascinated and awe-struck and a little creeped out, to be honest! Would you dive into a red lake?

I love it when nature throws us a curve ball. Tell me: What’s the strangest natural phenomenon you’ve ever seen?
