Lake Turkana
Lake Turkana stretches through the arid northern reaches of the East African Rift. The Omo River enters at its northern end, while the Turkwel and Kerio flow toward it from the west. With no outlet to the sea, the lake loses water through evaporation, leaving its waters alkaline. Volcanic islands rise from the broad lake, whose shores and islands provide breeding grounds for Nile crocodiles and refuge for many waterbirds.
