Geysers of Yellowstone   



  Big Cub Geyser
Feature Type: Geyser
Geyser/Spring Type: Cone geyser

Upper Geyser Basin
Geyser Hill

Big Cub is a member of the Lion group of geysers, and as such, its eruptions should be visible from all over Geyser Hill, the Old Faithful Visitor Center, and so on. The problem is that Big Cub almost never erupts. The last known eruption was in 1998, and "intervals" lasting decades are by no means uncommon. When it does erupt, it's spectacular, reaching heights up to 50 feet and lasting 4 minutes or so. It and Lioness, which also erupts exceedingly rarely, do splash and sputter from time to time, but alas, these sputs generally don't lead to eruptions.

What to look for:
If you are fortunate enough to see an eruption of Big Cub, by all means report it to the Old Faithful Visitor Center. Make sure, however, that Big Cub is really the geyser that you saw. It erupts from the "right rear" cone on the platform as seen from the boardwalk and bench in front of Lion. Similarly reluctant (and reportable) Lioness is beside it, and Little Cub to the left of both. Be particularly sure you haven't witnessed an eruption of Little Cub, which is active and frequent.
