Doublet Pool is a hot spring in the Upper Geyser Basin of Yellowstone National Park, Wyoming.

Doublet Pool is 8 feet (2.4 m) deep and its temperature is approximately 194.4 °F (90.2 °C).[3] Its scalloped edge is made of geyserite. Eruptions can occur in Doublet Pool, but only last up 8 minutes. The pool on the right pulses over the vents about every two hours.[4] Occasionally there will be vibrations, surface wave motion, and thumping; these effects are caused by collapsing gas and steam bubbles deep underground.[5]
