Summary

Description Boiling lake in Yellowstone National Park.Once Churning Caldron was a cool spring covered with colorful mats of microorganisms. This all has changed after earthquakes in 1978-79 superheated the water and killed the microbes. This once cool pool now averages 164°F and in 1996, it began throwing water 3-5 feet.
