Lake Natron is on the border of Tanzania and Kenya. It is formed by hot springs rich in minerals such as sodium, alkaline and magnesium. High levels of evaporation in the dry season cause the alkalinity of the lake to reach a pH as high as 9 to 10.5 and the water to become as shallow as tens of centimeters, thus revealing the colorful patterns at the bottom of the lake, like an uncanny workmanship of nature. The lake is the paradise for the flamingos, which often fly over the lake in groups. In September 2019, I was lucky enough to be at the right place and right time to capture those photos.
