Yellowstone National Park features a great variety of land forms and beauty.  The geysers get your attention, then, as they flow into rivers, the rivers take your eye.  Follow the view of the river, and look up. You'll probably see either a  mountain or one of the many park animals, bison, bear, elk, or moose.  Oops, I forgot the waterfalls, and don't forget Yellowstone Lake.  It is beautiful, serene, and fishable.  This national park may make your eyes tired from looking at all the amazing sights.
