| The colors are fascinating and beautiful. |
| Some of the pools are so clear that it seems you can see all the way to the core of the earth. |
| When you get close to these guys, they are so big. In fact, males can grow to weigh as much as 2,000 pounds. |

| Although the bison are wild and dangerous, for the most part, they are not affected by human presence. |
