Steamboat Geyser, the world's tallest active geyser, has been mostly inactive in 2025. After several years of frequent but unpredictable eruptions, the geyser in Yellowstone National Park's Norris Geyser Basin has only erupted twice this year.

Steamboat Geyser could erupt tomorrow, next week or next year. It might also not erupt again for decades, as has happened in the past.

There's still steam rising from Steamboat, but everything indicates that the world’s tallest geyser has, somehow, lost its steam. It's always kept its own schedule, so nobody can be certain when it'll go again.

Breaking Its Own Pattern

The last major eruption of Steamboat Geyser, which sent water 300 feet into the air, occurred on April 14 .

It's been more than 230 days since the previous eruption.
