Dear Jane!
Yellowstone National Park is a unique park in that there is a huge volcano under it, and if it starts to erupt, the whole sky will be covered with ash clouds for 10 years. And this is enough for everyone to die on Earth. But scientists doubt that there is a volcano. And yes, I sat down this reserve! It was pretty cool there! Yellowstone National Park on the map is located in several states: Montana, Wyoming and Idaho.
Надеюсь поможет!
