Steamboat Geyser

A crowd gathers to watch Steamboat Geyser on Sept. 17 in Yellowstone National Park. Steamboat erupted again on Saturday, setting a new record of 30 eruptions in 2018. Before this spring, the geyser hadn't erupted since 2014.

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.

Steamboat Geyser

Steamboat Geyser erupts Sept. 17 in Yellowstone National Park. It is the tallest geyser in the world and extremely unpredictable, with the time between eruptions ranging from four days to 50 years. 

The geyser erupted March 15 for the first time since 2014. That event not seen in person, but a June 4 eruption witnessed by scientists shot water at least 200 feet into the air.

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.
