formed when calcium-bearing freshwater springs well up through the carbonate rich alkaline lake water. They show that the lake was much deeper in the past.

Other comments

• Mono Lake became meromictic between 1994 and 2005. (A 11 year interval of meromixis).

• It’s normal state is monomictic, where seasonal flucuations is surface density driven by temperature variations cause yearly overturning of deep water with oxygen rich surface waters.
