Lake Afrera is a hypersaline lake located in the Danakil Depression in northern Ethiopia. Rock salt has been mined at the lake for centuries. More recently, some companies used to produce salt by pumping brine into artificial ponds for evaporation and subsequent precipitation. Following the 2011 eruption of nearby Nabro volcano, the lake is contaminated with sulfuric acid, making the salt inedible. The single island in the lake, Franchetti Island, is considered the lowest-lying island in the world. The image covers an area of 20 by 33 km, was acquired April 25, 2014, and is located at 13.3 degrees north, 40.9 degrees east.
