The hidden science and power behind Yellowstone geysers

Park Geologist Hank Heasler explains that in the 1860s, mountain scenery and wildlife were common across the Rockies. The single unique feature that prompted Yellowstone's creation was its bizarre thermal features.

Why Yellowstone Really Became the First National Park

Over half the world's geysers are in Yellowstone

Yellowstone hosts over 500 of the world's roughly 900 geysers, creating the highest concentration of active hydrothermal features on the planet.

Half of the World's Geysers Exist in One Single Park

A speaker explains the mechanics of geysers acting like nature's pressure cookers, releasing trapped superheated water into steam and blasting water high into the air.

How a Geyser Operates Like a Massive Pressure Cooker

Geysers are mathematically chaotic systems

Hank Heasler details why tiny shifts in underground water supply, heat, and rock plumbing cause dramatic, unpredictable variations in geyser eruptions.

Why Geysers Are Mathematically Chaotic

The interval between Old Faithful's eruptions has stretched from 60 to 90 minutes over the last 30 years, raising questions about its natural geologic future.

Will Old Faithful Ever Stop Erupting?

A park ranger reminds us of the spiritual and emotional value of preserving raw nature while a colossal geyser erupts before an amazed crowd.
