9Yellowstone National Park, the first national park in the country, contains many different types of ecosystems and many animals call the park home. Yellowstone Lake, in the middle of the park, sits on top of the Yellowstone Caldera, North America's largest supervolcano. As an area of active volcanism, it is of extreme interest to geologists.

In this young reader's book, the author lays out the history of Yellowstone in its many facets. He includes geological and volcanic history, ecological history, human history, and its history as a park.

By weaving these all together, the author allows the reader to better understand the oldest US National Park.

What else is Yellowstone hiding? Hot springs, geysers, and volcanic rock show there might be more going on underneath the surface. What happened to the petrified trees? What's happening to the bison and other animals? Who lived in the area long before it became a park? These questions and more are answered in All About Yellowstone.
