The Fossil Falls is a unique geological feature, located in the Coso Range of California in the United States. Volcanic activity in the mountain range, along with meltwater from glaciers in the nearby Sierra Nevada, played a role in the creation of the falls. They are located near Little Lake, Inyo County, California, 1.0 mi (1.6 km) off US 395 (at a red cinder cone called "Red Hill") on Cinder Road to Red Hill, with signs to Fossil Falls.[4]
