America's Best Known National Park
First established as a National Park in 1872, Yellowstone remains America's best-known National Park for its geothermal features, array of wildlife and stunning scenery. It covers three states--Wyoming, Idaho, and Montana--however, most of the park lies in Wyoming. The best known parts of the park are the Old Faithful Geyser and the Grand Canyon of the Yellowstone.
Geysers, Volcanoes and Geothermal Features

The largest volcanic system in North America lies in Yellowstone National Park. With constantly erupting geysers, bubbling hot springs, and a "supervolcano" system historically erupting every 600,000 years or so, Yellowstone is a huge attraction drawing nearly 3 million visitors per year.

The Super Volcano
Yellowstone National Park is under great scrutiny from geologists for its geothermal activity. Most of the park is actually a giant caldera, or volcano hole, with a giant magma chamber 4 miles beneath the park's surface. This magma chamber is what powers the parks geysers, pools, and of course, Old Faithful. The giant caldera is referred to as a "supervolcano" because of its catastrophic history. Scientists have confirmed that there is no reason to believe there is an eruption in the near future, nor that we are "overdue."
Sulfur pools
Old Faithful...you've heard of it many times, and probably have seen it on TV. Old Faithful is just one of hundreds of geysers in Yellowstone. It erupts every 74 minutes at a height between 100-180 feet for up to 5 minutes straight. The water temperature has been measured at 204 degrees, while the steam is a scorching 350 degrees!
You'll notice in the picture above the azure blue color of the pools. This is created from black bacteria dying off when the pool heats up from thermal activity.

More About Volcanoes...
- Volcanoes Are Hot Stuff
- Volcanoes are some of the most terrifying and magnificent wonders of our restless planet. Scientists have learned a great deal about volcanoes in the last century or so, but when a volcano stirs, all we can do is get out of the way.

- The Mighty American Bison
- These large, intimidating creatures were once on the verge of extinction until they were reintroduced into Yellowstone National Park and on Elk Island in Alberta, Canada. Bison are commonly called "buffalo" by many, however, they are technically bison.
- Grizzly Bears
- The brown bear (known as the grizzly in the Lower 48 states) is a large predator distinguished from black bears by a distinctive hump on the shoulders, a dished profile to the face, and long claws about the length of a human finger.
- Gray Wolves are being taken off the Endangered Species List
- Wolves were once abundant over much of North America and Eurasia but now inhabits a very small portion of its former range because of widespread destruction of its habitat, human encroachment of its habitat, and the resulting human-wolf encounters that sparked attempts of total extermination.
- The Magnificent Moose
- A lens all about moose, featuring moose merchandise and more.
Grand Tetons National Park
Nearby to Yellowstone and included in the Greater Yellowstone area is the Grand Tetons National Park. Its high peaks contrast with the comparatively low-lying valleys, lakes and meadows below offer some of the best photography, hiking, and camping of any of the National Parks. What makes the Grand Tetons unique are its lack of foothills leading up to the glacier-topped mountains.

Yellowstone is unbelievable, but I haven't been in the winter. I'd love to do that someday, and take a trip to the Tetons during that time of year while I'm at it. Posted September 29, 2008 |

Had to re-visit you since I came back from Wyoming. Yellowstone is indeed fabulous. I found it a bit surreal. I visited in May when it was still snowing, and steam was rising from the lakes and ground. It's just weird to see mud boiling! Posted September 27, 2008 |
