Trona in San Bernardino County, California — The American West (Pacific Coastal)
Welcome to the Trona Pinnacles
... a National Natural Landmark
The Pinnacles were formed between 10,000 and 100,000 years ago when Searles Lake formed a link in a chain of interconnected lakes flowing from the Owens Valley to Death Valley. At one point during the Pleistocene, the spot where you are standing now was under 640 feet of water.
The Trona Pinnacles were designated as a National Natural Landmark by the U.S. Department of the Interior in 1968 to preserve one of North America's most outstanding examples of tufa tower formation.
Erected 2000 by U.S. Department of the Interior.
