Yellowstone National Park's Steamboat geyser is breaking records with 34 eruptions so far this year as of early September.

The famous attraction is the world's tallest active geyser and has broken its own record for the most eruptions set last year at 32, according to the National Park Service, and there's still months to go before the end of the year.

Steamboat's eruptions are unpredictable, the Park Service said, and over the years have been sporadic, with active years in 1982 - 1983 after being dormant for 50 years, quiet years throughout the 1990s and 2000s, and other years of dormancy marked by a single eruption.

"One thing is known, Steamboat Geyser's future eruptions will continue to be unpredictable, officials said on the Park Service's website.
