The Sahara Desert is located in the northern part of Africa. It stretches from the Atlantic Ocean to the red sea, covering one fourth of the continent. It you wanted to hide the entire continental United states, you could bury it under Sahara. Only a small part of the Florida Peninsula or the southern tip of Taxas would stick out. Should you decide to walk the length of the Sahara at a rate of eight kilometers a day, it would take you almost two and a half years!
