Yellowstone: Boiling Mud Pots

Riley particularly enjoyed a stop at some boiling mud pots. We walked along the boardwalk and saw a lot of steaming and bubbling pits of sulfur mud. She was fascinated by the "blub, blub", noises from some of them and the almost rushing, wave-like noises of others. Like all stops, she had to stay right next to us so she didn't wander into boiling mud!
