Mono Lake – California
download (2)
Mono Lake is a large, shallow lake with no outlet to the ocean. The lack of an outlet causes high levels of salt to accumulate. Although its high alkalinity is not livable for fish, it still has an unusually productive ecosystem. The brine shrimp which thrive in its waters provides food for two million migratory birds which nest there annually.
