Jet Geyser

Jet Geyser is a thermal spring in Yellowstone National Park's Norris Basin with multiple vents that shoot water and steam in different directions. Eruptions typically reach heights of about 20 feet and occur at unpredictable intervals.

The geyser formed through volcanic activity that began thousands of years ago in Yellowstone and continuously shaped thermal features in the region. Its behavior and structure reflect the complex geological history of this geothermal area.

Scientists and researchers study Jet Geyser's unpredictable eruption patterns to understand the complex hydrothermal systems beneath Yellowstone's surface.

Visitors can watch eruptions from designated wooden boardwalks while maintaining a safe distance since the expelled water reaches very high temperatures. The best viewing conditions typically occur during early morning hours or in clear weather.

Eruptions follow no fixed pattern and change their frequency and intensity over time, which constantly surprises scientists monitoring the site. This unpredictable behavior means every visit offers a new experience since nobody can precisely predict when or how forcefully the next eruption will occur.
