The spring emits a roaring sound reminiscent of a dragon's breath, caused by steam and gas explosions within the cave-like opening.
The constant churning of the water is due to the continuous release of carbon dioxide and steam from underground.
It is located in the Mud Volcano area, which is known for its acidic hot springs and mud pots.
The water temperature can reach up to 170°F (77°C), making it too hot for any form of life to survive.
The geothermal activity can alter the landscape, causing features to grow, shrink, or even disappear over time.
The spring emits a strong sulfur odor, often compared to the smell of rotten eggs, due to hydrogen sulfide gas.
Bison and other animals are often seen near the spring, attracted by the warmth during colder months.
