Arizona (Ringbolt) Hot Springs
Arizona (Ringbolt) Hot Springs, also known as simply Ringbolt Hot Springs or Arizona Hot Springs, is a group of three geothermal springs located near Hoover Dam, Arizona. They are located on the Lake Mead National Recreation Area. The hot mineral water emerges from the spring in the upper canyon at 110 °F. The water then flows over a 25-foot waterfall where it is cooled to 95 °F and collects in a gravel-bottomed rock soaking pool accessible by a ladder.
