description Mud Caldron Overview
Mud Caldron is a large, active mudpot located in the Mud Volcano thermal area of Yellowstone National Park in Wyoming. It consists of a highly acidic hot spring where microorganisms consume sulfur and produce hydrogen sulfide gas, resulting in a muddy, bubbling consistency. The feature has been historically described as being roughly 40 by 60 feet across, though its size and activity can fluctuate with geothermal changes. Visitors to the park's lower loop can observe the Caldron from designated boardwalks.
