Sulphur Spring, Thermal spring in Hayden Valley, Wyoming
Sulphur Spring consists of a steaming pool with a central vent reaching temperatures of 89 degrees Celsius in the Crater Hills area.
The spring emerged through geological processes that formed Yellowstone's thermal features during the development of the North American continental plate.
Native American tribes incorporated the spring's mineral-rich waters into their traditional practices before the establishment of Yellowstone National Park.
Visitors must maintain a distance of at least 25 feet from the spring's edge due to the extreme water temperatures and unstable ground.
The spring contains specialized thermophilic bacteria that thrive in temperatures exceeding 80 degrees Celsius, creating distinct mineral formations.
