Stunning Mono Lake's located on the extreme western edge of the Great Basin, which stretches across Nevada to the Wasatch Range in Central Utah. Streams and rivers flowing into this region never reach the ocean – instead, they flow into desert valleys or into lakes such as Mono Lake that have no outlet.
Streams carry small amounts of salts and minerals into Mono Lake, where they have built up over hundreds of thousands of years (the lake is one of the oldest in North America). As a result, Mono Lake is more than twice as salty as the ocean and very alkaline.
Mono Lake’s strangely beautiful tufa towers result from calcium-rich spring water bubbling up from the bottom of the lake into the alkaline lake water.
