Star Trails over Trona Pinnacles ... explored
The Trona Pinnacles are an unusual geological feature in the California Desert National Conservation Area. The unusual landscape consists of more than 500 tufa spires, some as high as 140 feet (43 m), rising from the bed of the Searles Lake (dry) basin. The pinnacles vary in size and shape from short and squat to tall and thin, and are composed primarily of calcium carbonate (tufa). During the Pleistocene, massive runoff spilled from the Sierra Nevada into a chain of inland seas. The system of interconnected lakes stretched from Mono Lake to Death Valley and included Searles Lake.
Deep beneath Searles Lake, calcium-rich groundwater and alkaline lake water combined to grow tufa formations. Similar (modern) formations can be found today at Mono Lake to the north.
Known as tufa pinnacles, these strange shapes formed underwater 10,000 to 100,000 years ago. (Wikipedia)
