TitleTufa at Mono Lake, California, USA
DescriptionThe tufa towers in the background formed when freshwater springs interacted with Mono Lake water, leading to the precipitation of calcium carbonate (calcite). Salt deposits can also be seen on the bushes in the foreground. Salt, alkalis, and other minerals have washed into Mono Lake for many years and, because the lake continuously evaporates, the concentration of the disolved material increases. Mono Lake is today much more salty and alkaline than the ocean. Mono Lake levels go up and down, depending in large part on the rate water is withdrawn to supply Los Angeles. Today the lake level is rising, so the towers are not as large as they once were.
