Mud Volcano

Yellowstone National Park

A fairly subdued geothermal area near Fishing Bridge, Mud Volcano still delights with the huffing, steaming maw of Dragon's Mouth Spring and the spectacle of the former forest of Cooking Hillside, where in 1978 the ground temperature reached 200°F (93°C), searing roots and toppling trees.
