![]() While the environment is too harsh for most common types of life, there are some species that take advantage of it. ![]() The mixture moves through the ground via a system of faults and wells up in more than 20 hot springs that ultimately empty into the lake. Volcanoes, such as Ol Doinyo Lengai (about 20 kilometers to the south), produce molten mixtures of sodium carbonate and calcium carbonate salts. Evaporation usually exceeds that amount, so the lake relies on other sources-such as the Ewaso Ng’iro River at the north end-to maintain a supply of water through the dry season.īut it’s the region’s volcanism that leads to the lake’s unusual chemistry. In a non-El Niño year, the lake receives less than 500 millimeters (20 inches) of rain. In these images, you can see the deepest water along the perimeter of the lake bed, the location of lower-elevation lagoons. They show the lake on March 6, 2017, very early in the rainy season that runs from March to May. The Operational Land Imager (OLI) on Landsat 8 captured these natural-color images of Lake Natron and its surroundings. The lake is mostly inhospitable to life, except for a few species adapted to its warm, salty, and alkaline water.īut you don’t need to visit the lake in person to see its stunning, seasonal color. Not many people venture near the shores of Lake Natron in northern Tanzania.
