The yellow Sahara is the postcard image of a desert. A waving sea of sand. Passing dunes. Date palms oases breaking up the onerous journey. A Fata Morgana mirage appears in the distance. Like no other desert, the Sahara embodies the romantic ideal and lost dream of the infinite. The uniform rhythm of the camel's gait lends the slow trip a certain monotony. Not so the landscape: The old caravan road surprises with unexpected limestone formations, mountains and endless sand.
