Thanks Ann and Kelly. The rock-like formations are called tufa (too’-fah). Typically, underwater springs rich in calcium mix with lakewater rich in carbonates. As the calcium comes in contact with carbonates in the lake, a chemical reaction occurs resulting in calcium carbonate—limestone. The calcium carbonate precipitates around the spring, and over the course of decades to centuries, a tufa tower will grow. Tufa towers grow exclusively underwater, and some grow to heights of over 30 feet. The reason visitors see so much tufa around Mono Lake today is because the lake level fell dramatically after water diversions began in 1941. - Larry
Betcha this is Mono Lake tufa. This is just wonderful Larry. Love the complementary colors - the orange light and purple toned tufa. And the quality of light is wonderful. Lovely! Ann C
