The Trona Pinnacles is one of the most unusual geological features in the California Desert Conservation Area. The unusual landscape consists of more than 500 tufa spires, some as high as 140 feet, rising from the bed of the Searles Lake. The pinnacles vary in size and shape from short and squat to tall and thin, and are composed primarily of calcium carbonate (tufa) that formed underwater. They now sit isolated and slowly crumbling away near the south end of the valley, surrounded by many square miles of flat, dried mud and with stark mountain ranges at either side.
