Yellowstone: 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 unique underground volcano system of Yellowstone


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.

Castle Rock Geyser
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.

- 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.

- This past summer several friends in my scout troop and I hiked through there for 2 weeks and it was the best trip of my lives. ANIMALS EVERYWHERE. We saw about 2 dozen bears throughout the trip. It was almost like being in Jurassic park because at times we felt like we were no longer at the top of the food chain.
If you don't go hiking or backpacking down the trails then you haven't really seen Yellowstone. You have to spend a night out where you listen to the wolves howl and watch the eagles soar above you

Yellowstone Books & Guides
Yellowstone is a very large area. Large enough that you could miss some of the hidden gems located in the park! It's so large that bison hid out here in the 1800's (unintentionally?) to avoid being totally decemated as a species and managed to be virtually undetected. An area this large needs a good guide book! Read up on Yellowstone with this top rated guides on Amazon. All have excellent reviews.
An Interesting Take on Yellowstone
This is very different, morbid take on Yellowstone. The author airs on the side of caution, telling the tales of the unfortunate people that have perished in Yellowstone National Park. Some 250 people have died from incidents natural and man made...some could have been prevented, some not. There are many perils in the parks that you may not know about! From landslides, avalanches, hot geyser blasts, car accidents, bison goaring (!), bear attacks and plane crashes, anything can happen here.
