The land around geysers and hot springs is generally unstable, so the park service builds boardwalks so that people don't accidentally break through and fall into boiling water. The boardwalk around Old Faithful was constructed of recycled plastics, so for a buffalo it's like trying to walk on ice. Watching this herd slip, trip, and slide across the boardwalk is something I won't forget for a very long time.
