“A wigwam or wickiup is a domed room dwelling used by many different Native American cultures. The curved surfaces make it an ideal shelter for all kinds of conditions. These structures are formed with a frame of arched poles, most often wooden, which are covered with some sort of roofing material. Details of construction vary with the culture and local availability of materials. Some of the roofing materials used include grass, brush, bark, rushes, mats, reeds, hides or cloth.”
