Description
Tufa is essentially common limestone. What is uncommon about this limestone is the way it forms. Typically, underwater springs rich in calcium mix with lake water rich in carbonates. As the calcium encounters carbonates in the lake, a chemical reaction occurs resulting in calcium carbonate---limestone. The calcium carbonate precipitates around the spring, and over the course of decades to centuries, a tufa tower will grow.
A solitary Tufa tower stands guard over the chlorides, carbonates, and sulfates lake. It is alkaline, with a pH of 10, and almost three times as salty as the ocean. At 6,392 feet it will be slightly more than twice as salty as the ocean.
Mono Lake sits at the entrance to the Tioga Pass into Yosemite National Park at the intersection of US 395. Supported by a local community, Lee Vining, CA; the community provides visitor accommodations and visitor information on the lake and Tufa formations.
