boiling spring
Scalding natural pool
A boiling spring is a natural spring where water emerges at or near boiling temperature, typically heated by geothermal activity.
The term also applies to springs that appear to boil due to vigorous bubbling from gas escaping through the water, even when the water itself is cool: The boiling spring churned with sulfurous fumes.
