    There are a variety of fairly unique geothermal features accessible from the Mud Volcano Trail and boardwalk. Bison use the area for bug repellent and are a common sighting.

      The Mud Volcano Area is one of the most intense and curious thermal areas in Yellowstone National Park. It differs from other basins in its predominantly acidic mud pots and strong sulfur odor.
      The uniqueness of the Mud Volcano lies in the formation of its mud forms.
      Certain microorganisms use this gas as an energy source, converting it into sulfuric acid.
      This acid dissolves the surrounding rock into clay and wet mud. The rising gas causes the mud to simmer, bubble, and splash. The consistency and activity of the mud pots changes depending on the season and rainfall.
      The pungent smell of rotten eggs is due to the escaping hydrogen sulfide gas.
