"The Mono Lake Tufa State Reserve is located near Yosemite National Park within Mono County, in eastern California. It was established in 1981 by the California State Legislature, to preserve the natural limestone ""tufa tower"" formations at Mono Lake calcium-carbonate spires and knobs formed by interaction of freshwater springs and alkaline lake water. It also protects the lake surface itself as well as the wetlands and other sensitive habitat for the 1 to 2 million birds that feed and rest at Mono Lake each year."
