Although these pictures of Yellowstone are pretty, they don't give a very clear feeling of the amount of geothermal activity in the area. One really gets the feeling that you are sitting on top of a major hot spot when you are there.

This water fall was incredible, just the massive size of it and the balloon of spray. The first picture includes the foot path down to the over hang, it kind of give an idea of the size of the falls. The whole park is just awesome! There is a lot of evidence of damage from the pine bark bores and a major fire that went through in 1988 (I think it was).
