America's first national park located in the states of Wyoming, Montana, and Idaho.

The human history of the Yellowstone region goes back more than 11,000 years. From about 11,000 years ago to the very recent past, many groups of Native Americans used the park as their homes, hunting grounds, and transportation routes.

Things to Do

Hiking, camping, fishing, enjoying exhibits and films, and attending Ranger-led programs are among the many ways you can enjoy Yellowstone National Park.

Climate

Yellowstone's climate is one of cold winters and moderate summers. Most of the park is above 7,500 feet and the weather is unpredictable. Be prepared for changing temperatures, storms and emergencies.

There were no wolves in Yellowstone in 1994. The wolves that were reintroduced in 1995 and 1996 thrived and there are now over 300 of their descendents living in the Greater Yellowstone Area

The 1988 fires affected 793,880 acres or 36 percent of the park. Five fires burned into the park that year from adjacent public lands. The largest, the North Fork Fire, started from a discarded cigarette. It burned more than 410,000 acres.
