Geysers of the World   

Geysers of Yellowstone   



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

Upper Geyser Basin
Giant Group

Catfish Geyser often erupts for short periods of time to about 10 feet. These small eruptions can occur during a Giant Hot Period but do not seem to have much significance to the Hot Period. They also occur outside of the Hot Periods. For the most part none of these eruptions are too inspiring. This can all change, though, during a Mastiff Function eruption of Giant Geyser. During some Mastiff Function eruptions, Catfish will join Mastiff and Giant in the eruption and erupt in a narrow jet for as many as 5 minutes and up to 75 feet tall.
