Mono Lake formed at least 760,000 years ago as a terminal lake in a endorheic basin is a saline soda lake located in Mono County, California's Eastern Sierra. The lack of an outlet causes high levels of salts to accumulate. these salts also make the lake alkaline. Mono Lake is an oasis in the dry Great Basin and a vital habitat for millions of migratory and nesting birds.
