Living at the furthest corners of the hot and dry Sahara Desert, the very margins of where elephants can survive, hundreds of these great creatures make a dangerous but necessary journey as their main source of food and water dries up and they must go in search of more. Battling 120-degree heat, sandstorms, and fierce thunderstorms, these amazing animals travel 35 miles a day in a race against time in search of the bare essentials of life.
