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.
