Ten-story-high sand dunes, eye-tricking mirages, unlucky explorers – it’s all here and more in this newest Where Is? book. From the #1 New York Times Best-Selling Who Was? series comes Where Is?, a series that tells the stories of world-famous landmarks and natural wonders and features a fold-out map! Imagine over three million square miles of sand dunes that are as tall as a ten-story building. That place is real -- it's the Sahara Desert! Vast, yes! And home to fascinating creatures such as ostriches and fennec foxes as well as amazing plant life. The shallow roots of the mesquite tree can grow almost 200 feet across to absorb water. Readers will also learn about the famous trade routes of the past with caravans of up to 10,000 camels, European explorers to the region (some very unlucky ones), and [local] populations like the [Amizigh] and Tuareg, the faces of the men are blue from the dye in the veils they always wear.
