1. Black Dragon’s Caldron Marker
This mudpot roared into existence in 1948, blowing trees out by roots and forever changing this once quiet forested hillside. A park interpreter named the new feature for its resemblance to a darkly colored “demon of the backwoods.” For several decades, it erupted in explosive 10 – 20 foot bursts of black mud. Over the years, it has moved 200’ to the southeast and become relatively quiet. However as change is constant in Yellowstone, the black dragon may one day roar back to life.
