Yellowstone In Depth Video Series

What have we discovered about Yellowstone's wildlife, geysers, and other natural features? How can we learn from the park's history to help us protect its future? In this video series, explore Yellowstone's most popular questions and important issues with park rangers, scientists, historians and park visitors. Discover more about the world's first national park: experience Yellowstone In Depth.

 

Waters of Yellowstone
People are drawn to water, and there's so much water in Yellowstone—rivers, lakes, hundreds of waterfalls, geysers, and hot springs. Water can flow very quietly and slowly. It can be loud and roaring and raging and fast. And then there is Yellowstone Lake, which is like an ocean in the middle of our continent.

 

The Northern Range

The Northern Range is the hub of wildlife in Yellowstone National Park. It is winter range for the park's largest elk herd and is the most carnivore-rich area in North America. Early management of predators caused dynamic changes to the ecosystem. The reappearance of carnivores on the landscape has had significant and sometimes unexpected impacts.

 

Predicting Old Faithful
Old Faithful was once called "Eternity's Timepiece" because of the regularity of its eruptions. However, this geyser has never erupted at exact hourly intervals as many believe. Ranger Darlene Bos explains how we predict eruptions for this popular geyser.

 

Watershed Down
Snowfall in Yellowstone melts into rivers that span the continent from the Gulf of Mexico to the Pacific Ocean. Scientists are documenting significant changes in the amount of snow that falls here as well as the intensity and timing of spring runoff. These trends could affect everything you see when you come to the park, as well as everyone and everything living downstream.

 

Bison
Yellowstone preserves the most important bison herd in the United States. Learn more about the near extinction and recovery of these remarkable animals, how they make it through harsh winters, and what their survival says about our ability to share the landscape with another species.

 

Geysers
With over half the world's geysers, Yellowstone offers tremendous opportunities to see these geologic wonders in action. Explore the mechanics of geysers, their role in the park's history and what they teach us about the world in which we live.

 

Bears - A Yellowstone Love Story
Everyone loves the bears in Yellowstone. In the park's early years, people fed them along the roadside and they learned to beg and scavenge at hotels, campgrounds, and the park's garbage dumps. But was the era of the "beggar bear" ultimately good for the people or the bears? Find out how this love affair has evolved over time.

 

Yellowstone's Restless Giant
The Yellowstone supervolcano is one of our planet's restless giants. For scientists, the question is not one of whether it will erupt again, but rather, when. Are there signs this giant is reawakening? Could it erupt in our lifetimes? Discover how geologists are monitoring the pulse of the Yellowstone volcano.
