Ethiopia and Kenya - January 4th, 2012

Lake Turkana, formerly known as Lake Rudolf, is a lake in the Kenyan Rift Valley, with its far northern end crossing into Ethiopia. It is the world’s largest permanent desert lake and the world’s largest alkaline lake. By volume it is the world’s third-largest salt lake, after the Caspian Sea and Issyk-Kul (passing the shrinking South Aral Sea), and among all lakes it ranks twenty-fourth.

The rocks of the surrounding area are predominantly volcanic. Central Island is an active volcano, emitting vapors. Outcrops and rocky shores are found on the East and South shores of the lake, while dunes, spits and flats are on the West and North, at a lower elevation. Three rivers (the Omo, Turkwel and Kerio) flow into the lake, but lacking outflow its only water loss is by evaporation. Here, brown sediments can be seen entering the northern part of the lake, while the rest appears green from algal growth and minerals in the water.
