This exciting reader follows the story of the longest and the most demanding elephant migration on the planet. 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.National Geographic supports K-12 educators with ELA Common Core Resources.Visit www.natgeoed.org/commoncore for more information.
