Mono Lake, on the Eastern side of the California Sierra Nevada Mountains, is one of the most unique lakes in all of North America. Made up of chlorides, carbonates and sulfates, the lake itself is alkaline, with a pH of 10 and contains almost 3 times the amount of salt as the ocean. With an estimated age of 1-3 million years, it is one of the oldest if not the oldest lake on the continent.

According to www.monolake.org, “In 1931, the Los Angeles Department of Water and Power began diverting Mono Lake’s tributary streams 350 miles south to meet the growing water demands of Los Angeles. Deprived of is freshwater sources, the volume of Mono Lake halved and the salinity doubled. Unable to adapt to these changing conditions within such a short period of time, the ecosystem began to collapse.”


In 1978 David Gaines founded the Mono Lake Committee and began to lobby to anyone that would listen about the importance of Mono Lake. Through his leadership, the Mono Lake Committee grew to over 20,000 members and fought and won legal and legislative recognition for Mono Lake.



Today, Mono Lake embraces 14 different ecological zones, over 1000 plant species and roughly 400 recorded vertebrate species within its watershed. Mono Lake and its surrounding are encompasses one of California’s richest natural areas. If you ever get a chance to explore the region, I highly recommend it for Mono Lake is a sight to see.
