YELLOWSTONE | DRAGON’S MOUTH SPRINGS
Warning: watch where you park. The steam vents were coming up through the parking lot. Quite funny. Also, possibly quite dangerous.
Dragon’s Mouth Spring is a small pool backed up against a hillside where a water and steam spew out of a cave, producing a roaring sound. A sign at Dragon’s Mouth Spring reads:
“An unknown park visitor named this feature around 1912, perhaps due to the water that frequently surges from the cave like the lashing of a dragon’s tongue. Until 1994, this dramatic wave-like action often splashed water as far as the boardwalk. The rumbling sounds are caused by steam and other gasses exploding through the water, causing it to crash against the walls of the hidden caverns.”
