Erg Chigaga or Erg Chegaga is the largest and still untouched of the major ergs in Morocco. A caravan is a group of people traveling together, often on a trade expedition. Caravans were used mainly in desert areas and throughout the Silk Road, where traveling in groups aided in defense against bandits as well as helping to improve economies of scale in trade. In historical times, caravans connecting East Asia and Europe often carried luxurious and lucrative goods, such as silks or jewelry. Present-day caravans in less-developed areas of the world often still transport important goods through badly passable areas, such as seeds required for agriculture in arid regions. The Tuareg people also spelt Twareg or Touareg are a large Berber ethnic confederation. The Tuaregs have been called the `blue people` for the indigo dye coloured clothes they traditionally wear and which stains their skin. An erg also sand sea or dune sea, or sand sheet if it lacks dunes is a broad, flat area of desert covered with wind-swept sand with little or no vegetative cover. Morocco, Sahara, Africa.
