                 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.
