After years of silence, the world’s tallest active geyser set a new record over the weekend when it erupted for the 30th time in 2018.
Steamboat Geyser erupted in the early morning hours Saturday in Yellowstone National Park, according to a news release. The previous record of 29 documented eruptions was set in 1964.
The size and timing of eruptions depend on how much pressure has built in the reservoir of boiling water that feeds the geyser.
A major eruption of Steamboat may reach 300 feet. But the geyser is extremely unpredictable — the time between eruptions historically has ranged from days to years, including a 50-year dry spell from 1911 to 1961.
Steamboat Geyser is one of more than 10,000 thermal features in Yellowstone. It’s located in the Norris Basin, considered one of the most dynamic places in the park.
Most park roads are currently closed for the season. Weather permitting, roads are scheduled to open to snowmobiles and snowcoaches on Saturday.
