This otherworldly sunrise at California’s Mono Lake comes courtesy of Copeg’s photostream. Mono Lake is a geologic anomaly, a salt lake on the dry side of the Sierras that’s the oldest in the US. The jagged, tooth-like formations sticking up from the water are called “tufa”, they’re calcium carbonate towers that have grown out of the water over the centuries, as in-flowing spring water reacted with the highly alkaline body of the lake.
