Trona Towers
The Trona Pinnacles are near the mining town of Trona, California, southwest of Death Valley National Park. These unusual towers are deposits of tufa (calcium carbonate) that formed where calcium- rich springs discharged into a large, alkaline lake that filled Searles Valley during the ice ages of the Quaternary (Smith, 2009). Tufa towers like these near Trona are still forming in Mono Lake today.
