Steamboat Geyser eruption in 2019 (IMAGE) University of California - Berkeley Caption A 2019 eruption of Steamboat Geyser in the Norris Geyser Basin of Yellowstone National Park. The geyser's first documented activity was in 1878, and it has turned off and on sporadically since, once going for 50 years without erupting. In 2018 it reactivated after a three-and-a-half-year hiatus, for reasons that are still unclear.
