Grizzly Fumarole undergoes striking changes, depending on recent precipitation. It can be a large thin-watered mudpot, a series of smaller and thicker mudpots, or a fumarole (steam vent). During dry periods, it may look like an abandoned collection of mud formations with hot water hissing far below.
