Mono Lake, California, USA
One of the oldest lakes in the western hemisphere, Mono Lake is hauntingly beautiful, reflecting the snow-capped Sierra Nevada in its shimmering blue waters. An immense inland sea, the lake fills a natural basin, 695 square miles in size.
The most distinctive feature at Mono Lake is its eerie tufa towers-mineral structures created when fresh-water springs bubble up through the alkaline waters of the lake. The lake's salty water not only makes you float like a cork, but sustains trillions of brine shrimp, attracting millions of migratory birds to feast on them.
