The Dragon's Mouth Spring is one of my favorites in the park. It really does sound like a dragon breathing and seems like something out of an amusement park.
Grizzly Fumarole was pretty tame when we were there.
This buck didn't have a care in the world. I guess he didn't know the bison were fighting just over the hill.
Remember that I said we were there during the bison rut. That morning on our way to the corral we were stopped behind another Jeep and ended up in the middle of a buffalo fight. Two were fighting in the road and the winner ran in front of our Jeep, clipping it with his hip as he ran by. The only damage was a long scratch on the front driver's side fender, but he really shook the Jeep when he hit it! That was exciting, but I didn't have my camera ready in time. That evening as we did this hike in the Mud Volcano area, there were several buffalo right by the trail and there were quite a few people standing around trying to decide if we should continue the trail or not.
