How about Yellowstone’s own Grand Canyon? It has two big waterfalls and high cliffs of yellow, red, and orange rock There’s a forest of stone trees in Yellowstone that is millions of years old The trees were once buried by ash from a volcano and were gradually turned to stone There are also beautiful lakes, rivers, and mountains to see and enjoy Yellowstone is rich with wildlife Hundreds of kinds of birds live in the park, including bald eagles, blue herons, and white pelicans Yellowstone is home to many large animals Visitors may see black bears, grizzly bears, moose, bighorn sheep, deer, cougars, herds of elk, and bison (buffalo) Protecting animals in the wild is one of the most important tasks of the park In fact, the creation of Yellowstone helped save bison from being hunted to extinction in the late 1800s G Yellowstone was once home to thousands of gray wolves But people thought they were dangerous and killed them off The last wolf in the park was killed in the 1930s In 1995 and 1996, biologists brought about 30 wolves from Canada and released them inside Yellowstone Wolf packs soon formed New pups are born in the park every year There are now more than 200 wolves in and around the park! Today, seeing a wolf is one of Yellowstone’s big attractions
