Kepler Cascades, Waterfall on Firehole River, Yellowstone National Park, United States.
Kepler Cascades is a waterfall system on the Firehole River in Yellowstone National Park that drops through multiple stages over rocky terrain. The water descends approximately 150 feet (45 meters) through a series of flowing sections and pools.
The falls were documented by an early exploration expedition in 1870 and later named to honor a historical figure. This naming made them a recognized location on the park's first official records and maps.
The falls have been part of the park's public identity since early tourism, appearing in photographs and visitor accounts that shaped how people understood this landscape. Today, travelers still gather at the viewing areas to experience the river's dynamic water displays.
The location is easily accessible right along the park's main road with a nearby parking area and short walk to viewing points. The access is straightforward and works well for visitors passing through on their way to other park destinations.
The river receives inflows from thermal springs in the area, warming the water and creating unusual temperature conditions downstream. This mixing of cold and hot water produces special conditions that affect what lives in and around the falls.
