Doublet Pool, Hot spring in Yellowstone National Park, US.
Located in the Upper Geyser Basin at 7,356 feet elevation, Doublet Pool features a scalloped edge composed of geyserite and reaches temperatures of 194.4°F.
The geothermal formations at Doublet Pool developed over thousands of years through continuous mineral deposits and underground volcanic activity in Yellowstone National Park.
Native American tribes of the region have long recognized the spiritual and medicinal properties of the thermal waters in the Yellowstone area.
Visitors must stay on designated boardwalks and maintain a safe distance from the pool due to the extremely high water temperature and unstable ground.
The pool produces distinct vibrations, surface wave motions, and thumping sounds caused by collapsing gas and steam bubbles deep underground.
