The Mud Volcano Area, Yellowstone National Park

"Listen to the sounds, notice the smell, and observe the colors of the Mud Volcano area. Much of what you sense comes from sulfur. It is present in many forms: hydrogen sulfide creates the area’s infamous aroma, microbes convert the hydrogen sulfide into an acid that dissolves rocks and soil, and sulfur minerals paint the features in hues of yellow and shades of gray."
