How hot is the blue water in Yellowstone National Park?

Its temperature is near boiling, ranging in different spots from 63 to 87 degrees Celsius (145.4 to 188.6 degrees Fahrenheit). The dramatic colors are an interplay of physics, chemistry and biology. The blue color is an optical effect and the orange and brown colors are bacteria that live at temperatures near boiling.

Hot-spring water is usually fairly safe from the standpoint of carrying disease-causing organisms, but some is not (see below under Stay healthy), and the surface water that cools a scalding spring to usable temperatures will be prone to the same bugs and pathogens as any other surface water.
