Pink sky at Trona Pinnacles in the California desert.
This unique landscape consists of more than 500 tufa (calcium carbonate) pinnacles rising from the bed of the Searles Dry Lake basin. These tufa spires, some as high as 140 feet, were formed underwater 10,000 to 100,000 years ago when Searles Lake formed a link in an interconnected chain of Pleistocene lakes stretching from Mono Lake to Death Valley.
The Trona Pinnacles were designated by the Department of the Interior as a National Natural Landmark in 1968 to protect one of the nation's best examples of tufa formation.
