Here’s another picture of one of the hot springs in Yellowstone. The water is this beautiful turquoise color where it’s deep. You can judge the temperature of the water by the color of the bacteria living in it. The bacteria are called extremophiles because they can live in conditions that nothing else can survive in, in this case extreme heat.
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.
