See how blue that water is?

It's because that water is so fucking hot, that nothing can survive in it. Absolutely nothing. The water is so pure, that the color comes from the water-only-reflects-blue-light property.

WARNING, GRIM STORY AHEAD.

There are stories about people jumping into pools like this one for varying reasons. There was one story about a guy who had his dog without a leash, which is completely against the rules at Yellowstone. So he had it off the leash and the dog, for a reason no one but it knew, it ran into a pool just like this one. Now, this water is just below boiling. You know, 212F or 100C. So the dog jumps in and instantly starts to suffer. Its owner goes in after it. And within twenty seconds, he's no longer trying to save the dog but himself. He was in the water for less than five minutes, and had 3rd degree burns all over his body. 100% coverage. His buddy got 2nd and 3rd degree burns all over his hands and arms just trying to save the guy. His last words before being carted off to the hospital was "I can't believe I did that. That was so stupid." He died the next day.

Moral of the story: If the water's blue, and you're not by the equator, DON'T GO IN UNLESS YOU WANNA DIE A PAINFUL, PAINFUL, SKIN-SLUFFING DEATH.

That is all. It is pretty water, isn't it?
