The Hot Water Cascade is a natural thermal display at Hot Springs National Park in Arkansas where geothermal spring water at around 62°C flows freely down a moss-covered rock face alongside the park's Grand Promenade. The cascade has been a landmark since the development of Bathhouse Row in the 19th century. The thermal water creates distinctive mineral deposits on the rock face and supports heat-tolerant algae and microorganisms that color the cascade in shades of orange and green. It is one of the most visible and accessible of Hot Springs' natural geothermal displays.
