Doublet Pool is a hot spring in the Upper Geyser Basin of Yellowstone National Park, Wyoming.
Doublet Pool is 8feet deep and its temperature is approximately 194.4°F.[1] Its scalloped edge is made of geyserite. Eruptions can occur in Doublet Pool, but only last up to 8 minutes. The pool on the right pulses over the vents about every two hours.[2] Occasionally there will be vibrations, surface wave motion, and thumping; these effects are caused by collapsing gas and steam bubbles deep underground.[3]
