Weekly Photo Challenge: Danger! 

This is one of the hot springs at Yellowstone National Park. The water is superheated, it will cook your hand to the bone if you’re foolish enough to put your hand in it. You can see the bones of some small animal that fell in and died. 

The water is so hot, a bison fell into one of the springs a few winters ago and it was cooked to death before it could get out.
