Beehive Geyser in action.

The Beehive Geyser in Yellowstone National Park is known for its towering eruptions, but also its irregularity in terms of when these eruptions occur.

But as the Yellowstone Safari Company explained Tuesday via social media, there's a "little indicator" that signals an impending eruption.

The accompanying footage shows the indicator becoming active before the main event.

The company explained: “If you see that little spout start spitting water, that means that any time within the next 20 minutes, you will be treated to a geyser eruption that is both longer and taller than Old Faithful!”

According to the park, Beehive Geyser is a “favorite performer” in the Upper Geyser Basin, but only erupts once or twice per day at unknown times.

Eruptions typically last 4-5 minutes, and water columns can shoot 150-200 feet, so it’s quite a show.
