location
Mono Lake Tufa State Reserve. Near Lee Vining (Mono County, California, US)notes Tufa is a form of limestone precipitated when carbonate-rich source waters, usually from a fresh-water spring, enter an alkaline soda lake. It is likely that the source of the ground water in this area along the south shore of Mono Lake is a system of Sierra range-front faults. These lake-bottom tufa beds were deposited horizontally and subsequently tilted by the volcanic intrusions in the Mono Craters area south of the lake during the last 5,000 years. They were exposed in wave-cut terraces as the water-level in the glacially fed lake fell since the end of the Pleistocene.keywords: deposition, erosion, glaciation, limestone, nature, rock, tufa, uplift, volcanism, petrology, Holocene, earth science
