Mono Lake is a unique, ancient saline lake located in Eastern California near the Sierra Nevada. Over a million years old, it’s one of the oldest lakes in North America. The lake is known for its striking tufa towers—otherworldly limestone formations created by the interaction of freshwater springs and alkaline lake water. Despite its high salinity, Mono Lake supports a rich ecosystem, including brine shrimp and migratory birds. Its eerie beauty and ecological importance make it a fascinating natural wonder.
