Tufa is a calcium carbonate (CaCO3) deposit that forms by chemical precipitation from bodies of water with a high dissolved calcium content. Tufa is common in many parts of the world. There are some prominent towers of tufa at Mono Lake and Trona Pinnacles in California, USA, formed by precipitation from calcium-bearing spring water flowing into an alkaline lake (wiki 2009)
