Steamboat Geyser in Yellowstone National Park has erupted for the third time this year.
According to a Yellowstone press release, a park visitor reported seeing Steamboat erupt to park staff.
Comparing this report with seismic data, park geologists believe the eruption started around 6:30 a.m.
We previously reported Steamboat had erupted March 15, 2018. This was the first eruption for Steamboat since September 3, 2014. The geyser erupted again April 19, 2018.
According to the Geyser Observation and Study Association, this is the shortest interval between eruptions for Steamboat since 1982.
At this time, most of Norris Geyser Basin is still covered in snow and ice.
