This unique geological feature, called Trona Pinnacles, are located about 10 miles south of the mining community of Trona, in California’s desert. Rising out of the dried up bed of Searles Lake, the pinnacles are composed primarily of calcium carbonate, also known as tufa, and are very similarly to those found in Mono Lake.

The pinnacles vary in size and shape from short and squat to tall and thin. Some of the taller ones are as high as 40 meters.
