Geysers of the World   

Geysers of Yellowstone   



  Lioness Geyser
Feature Type: Geyser
Geyser/Spring Type: Cone geyser

Upper Geyser Basin
Geyser Hill

Most everything that was said about Big Cub Geyser also applies here: spectacular (reaching heights of 30 feet in the case of Lioness) and visible from the whole Upper Geyser Basin, Visitor Center, etc., when it erupts, but it almost never erupts. The last known eruption of Lioness appears to be as far back in time as 1971 (1952 according to some sources). Its cone still spits and sputs frequently, making it look as if an eruption is imminent, but the eruption never comes.

It has been found, or at least speculated (hard to be sure with a geyser as rarely active as this one), that there is an exchange of function between Lion Geyser on the one hand, and Big Cub and Lioness on the other; certainly it has been observed that the latter two erupt more frequently when Lion is dormant. However, since Lion is active most of the time (indeed, continuously for over fifty years), eruptions of Lioness are almost nonexistent, and presumably will remain so until Lion rests again.

What to look for:
If you observe an eruption of this geyser, please report it to the Old Faithful Visitor Center. However, make sure that it really is Lioness that you're seeing. Lioness erupts from the "center rear" cone on the Lion platform. Little Cub Geyser, to its left, is highly active, and its small (10-foot) eruptions don't need to be reported but are easily confused with possible Lioness events. (Big Cub, to the right, is also extremely rare, and its eruptions should also be reported.)
