A few weeks ago, we drove over to Mono Lake, a massive salty lake on the eastern border of Yosemite. I had seen the lake from afar before, and I knew it would be pretty, but I was still surprised by the beauty of this place. Around sunset, the sky was a bright hazy glow and the water had become a milky white. It was a stunning sight paired with the distant mountains and the dramatic tufa towers on the shores of the lake.
According to the Mono Lake Committee website:
Tufa is essentially common limestone. What is uncommon about this limestone is the way it forms. Typically, underwater springs rich in calcium (the stuff in your bones) mix with lakewater rich in carbonates (the stuff in baking soda). As the calcium comes in contact with carbonates in the lake, a chemical reaction occurs resulting in calcium carbonate–limestone. The calcium carbonate precipitates (settles out of solution as a solid) 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.
Interesting!

Looks “other worldly”. Cool!
Thanks so much!!!
