Lydia--what I learned

I learned many things. I had no clue that there was a major fire that cleared out all of the sick and old trees. I didn't know that Yellowstone is home to 2/3 of the world's geysers or that the whole park is on top of an active underground volcano. Also I knew there were a lot of animals that lived there but didn't realize how many NEED to live there. There are many animal reserves and reintroductions.

Everything I learned about Yellowstone makes it an important place. The fact that people can learn, listen, and watch history and facts about this great place makes me want to keep it forever.
