This single pool holds an astounding 84,600 cubic feet of water, making it not only the largest in Wyoming but also a contender for one of the biggest globally [2]. Thanks to the Sacajawea Well’s output, the entire pool is completely refilled every 11 hours, ensuring unparalleled freshness.

When considering what truly qualifies these sites as the largest hot springs in Wyoming, several compelling factors come to the forefront, distinguishing them from other geothermal areas.

This massive, continuous influx of water is the fundamental reason for their immense size.
