We who live along Montana's Yellowstone River are downstream from a simmering caldera, a geologic hot spot that has become especially active recently. Indeed, Yellowstone National Park contains the floor of a gigantic volcanic cauldron, one that rises and sinks with the forces that lie beneath — hence the picturesque geysers and steam holes. But a wave of recent earthquake activity is raising fears that have their origins 642,000 years ago, when a Yellowstone "supervolcano" exploded so violently that it created the caldera itself. Today, such an explosion — 1,000 times more powerful than the explosion of Mount St. Helens in 1980 — would not only cover most of the U.S. with ash but also throw so much dust into the atmosphere that the world's climate could change.

This is Yellowstone National Park’s first video web cam. This full-motion, live-streaming webcam is located near Old Faithful Geyser and brings online visitors views of several other geysers in the area. When geysers such as Beehive, Lion, or Giantess are erupting, the camera will be aimed at them and zoomed in for optimal viewing enjoyment. When bison, elk, coyotes, or the occasional bear wander into the camera’s view, live video images will be transmitted. We hope you enjoy your virtual park experience!
