This picture shows how Steamboat Geyser’s runoff looks during a minor eruption. According to Geysertimes.org, it’s been six days since the last major eruption of Steamboat Geyser, so it’s well within the expected window for its next one. So that is annoying to geyser gazers, but of course this is one of the last possible weeks to do any construction before the winter snows come.
The photo of Steamboat Geyser’s prodigious runoff channel, Norris Geyser Basin, was taken by Beth Chapple on June 28, 2019.
