Pumpkin Spring
United States
Pumpkin Spring is a geothermal heated mineral water hot spring located in the Grand Canyon in Arizona. The spring gets its name due to the bright orange mineral and organic deposits that have accumulated on the flowstone, giving it the appearance of a huge pumpkin. At the surface, the spring morphology is a mineralized carbonate mound-form. The spring water flows from within the pool which is surrounded by a travertine that has formed around the source. The water flows over the left bank lip of the mound down to the river at the upstream end of pool into the downstream side of the river.
