prairie schooner

Prairie Schooner, a wagon used for long-distance travel and freight transport in the nineteenth century. The wagon was made with six or seven arching wooden bows supporting a canvas cover. Seen from a distance, the vehicle so resembled a ship at sea as to suggest the name. Mormons, California gold-seekers, emigrants to Oregon, freighters operating on the Great Plains, and settlers seeking homesteads all used the schooner after it was brought into common use in the Santa Fe trade soon after 1821. It was not only the chief means for the transportation of goods, but it also provided a home for pioneer families as they journeyed west in search of land.
