A Hot Spring
 
At times, fierce, boiling waters within a hot spring (such as Crested Pool) can explode, shooting water into the air, acting much like a geyser. It is believed, however, that in the case of Crested Pool, no constrictions block the flow of water to the surface. The spring's wide mouth and 42-foot depth provide a natural conduit for superheated water to circulate continuously to the surface.
