The Trona Pinnacles are one of the most unique geological wonders in the California Desert. The unusual landscape consists of more than 500 tufa spires, some as high as 140 feet, rising from the bed of the Searles Dry Lake basin. The pinnacles, which vary in size and shape from short and squat to tall and thin, are composed primarily of calcium carbonate (tufa). The Trona Pinnacles have been featured in many commercials, still-photo shoots, and films such as Star Trek and Planet of the Apes to represent an alien planet. Need more time to take in this otherworldly landscape? Dispersed camping is allowed (see Bureau of Land Management website for restrictions). Want to see more tufa formations? Head north to Mono Lake.
