The prairie wagon is a classic image of the American West, but it's known by a variety of names depending on where you are. In some areas, it's called the covered wagon, because of the canvas or leather covering that provided shelter from the elements. Other synonyms include the conestoga wagon, named after the type of wood used to make the wagon's distinctive curved sides, and the chuck wagon, which was a mobile kitchen used by cowboys on cattle drives. Some people also refer to the prairie wagon as a stagecoach, though this term usually refers to a vehicle used to transport passengers rather than settlers moving westward.
