TitleTufa at Mono Lake, California, USA
DescriptionThese tufa towers formed when freshwater springs interacted with Mono Lake water, leading to the precipitation of calcium carbonate (calcite). Mono Lake levels go up and down, depending in large part on the rate water is withdrawn to supply Los Angeles.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 visible as they once were. 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.
