Black Dragon's Caldron
Black Dragon Cauldron is along a short boardwalk hike near Mud Volcano. Yellowstone is in many ways the ideal environment for dragons. Black Dragon Cauldron is a boiling mud pot similar to the Mud Volcano. While Mud Volcano is now just a pool having blown away its volcano top in 1872, Black Dragon Cauldron did not exist before 1948. It exploded into existence sometime before June of 1948, knocking trees down and showering the surrounding forest with mud. The marker is in Yellowstone National Park, Wyoming in Park County and can be reached from Grand Loop Road, on the left when traveling north. The marker's location is on a walking trail in the Mud Volcano area.
